In this series, we look at the changes in management that farmers and growers are taking in response to a changing climate. We’re looking at the tips, techniques and approaches that are borne out of the lived experience of farmers and growers, in response to a changing climate driven by global heating.
FCT exists to help food and farming businesses to reduce their carbon footprint, but increasingly every farming business also is having to adapt to the climate that we now have. It’s therefore vital that food and farming does both climate mitigation and adaptation at the same time.
Over recent years they have noticed a change in weather patterns, which has affected their farm in significant ways. Adam comments:
“The increasing frequency and intensity of high rainfall events coming with our changing climate are causing challenges in crop planning, and significant impacts on our soil. Soil erosion and water infiltration can be made much worse by heavy rainfall, especially in short amounts of time, as we’ve been experiencing.”
Indeed, research by EJP Soils shows that changes in rainfall patterns across Europe will be responsible for up to 23% more soil erosion by 2050. This could have very significant impacts on soil health, water quality and could lead to significant losses of soil carbon – the one major asset that farmers have to sequester carbon on their farmland.
The UK Met Office predict that rainfall will get more intense in both summer and winter over coming years and decades, in particular with very local variations; in other words, hard to predict and plan for.
Protecting the soil
Whilst we can’t influence the weather, we can respond to the weather patterns as we see them emerging. A good example is how we manage our soils, as this is so fundamental to food and farming. It is well known that leaving soil uncovered (in arable and horticultural systems) can lead to soil erosion, a decrease in soil organic matter, a loss of soil biodiversity, and other negative impacts on soil health and structure.
In turn, bare soil can have significant short and long term impacts on crop health, quality and yields. Water courses can end up being clogged up with soil and full of the nutrients that should be in our fields. Carbon can be oxidised and lost to the atmosphere, so that soils emit rather than sequester carbon.
Working out ways to change farming systems to be more resilient to these changes in climate will be critical for all farmers and growers. There are range of ways to build a more resilient soil, as Adam discusses:
“Over the last few years, we have changed our soil management practices. We’re working towards improving and maintaining soil health through regenerative principles. We’ve reduced tillage significantly, ploughing just one year in four now, and using pig tail tines as primary cultivation, with a power harrow. We’re also rotating some land with livestock and we’re very keen on keeping living roots in the soil as much as possible.
An example of standing water in tractor wheelings and a bed of carrots just harvested, with bare soil visible
Importantly we’ve really increased plant diversity and soil coverage. We’re constantly undersowing crops, so 80-90% of all fields have a green manure of some sort. This reduces exposure of soil to the weather, builds fertility and increases biodiversity.
There are three rotations across the market garden. Fertility building leys make up about 20-25% of land in any given year. Here we’re using 10-15 different varieties, including clovers, and annuals or biannuals – no long term grasses, we prefer cereals like rye oats and barley, plus winter wheat. We’re aiming to put in more deeper rooted species such as plantain, buckthorn, chicory, yarrow.
Deep rooting species can help improve soil structure and water infiltration
We also add manures (from our landlord’s organic farm), the amount being crop dependent. But with Soil Organic Matter levels at over 7%, we don’t need to add too much manure, and increasingly the green manures are performing that fertility building role.”
The impacts
Seeing is believing, and farmers and growers tend to learn a lot from looking at each other’s farms and understanding what others do differently. Knowing when something is working can be self-evident to farmers, not necessarily needing research to back it up.
At Pitney Farm Market Garden, Adam describes the impact of the changes they’ve made:
“Water infiltration rates on the areas covered by green manures are so much better; it’s obvious just to look at. There is no standing water on the green manures, even after heavy rain, whereas in the wheelings and a few bare beds there is standing water. This is evidence enough to me that we’re doing something right.
Kale with red and crimson clover undersown
Living plants cover the soil, reducing the speed and intensity that rain hits the soil. Roots help water sink into the ground, massively increasing infiltration rates and stopping the water running off the surface and carrying soil with it.
Soil improvements through Adam and Rita’s management have led to much improved water infiltration through better soil structure and aggregation
The healthier a soil is, with better aggregation, the faster the infiltration rate will be, meaning the larger amount of rainfall that the soil can deal with. We’re seeing good aggregation now in the top four inches of soil and lots of earthworms. We’re hoping that by introducing more deeper rooting species that aggregation will improve further down the soil profile.”
Bigger picture
When it comes to managing these issues of flooding and drought on a wider scale, Adam shares some thoughts:
“I’m coming to think that undersowing crops and ensuring the soil is covered, is actually an essential practice, not a nice add on. This is because of the increasing frequency and intensity of high rainfall events coming with our changing climate.
A lot of our agricultural soils in this country are in poor health. Many soils – particularly those under maize, are in very poor condition and have very little capacity to hold water. As the climate deteriorates, more and more farmers have to work harder and harder to produce crops, and do even more to protect our most precious resource, the soil, from harsher conditions.

Is the support, both technically and financially, in place to help farmers across the board to do this? Sadly, I really don’t think it is. The government doesn’t have a handle on it, and is not taking it seriously, which is really worrying. The climate crisis terrifies me on all sorts of levels. The impacts on global food supply chains and food security could be massive. We need to manage our soils better to both mitigate and adapt to climate change, as well as recreating our food systems to build resilience in food and farming.”
Written by Becky Willson, Business Development & Technical Director
On a sunny day in September, farmers gathered at Rotmell Farm to take part in a farm walk with our Soil Farmer of the Year Winner from 2020. Thanks to funding from the AFN+ network, we have been able to revisit two farms this year to understand how their farm and management system has evolved since being awarded.
Rotmell Farm is 1000 ha, 800ha of which is unimproved pasture – encompassing heather, bracken and wet areas. The farm sits in the middle of the Tay Valley, and watching how water was moving through the landscape formed a key part of the decision to adapt the management of the farm to focus on soil health and water holding capacity. In order to achieve this the grazing management system was adapted in 2015/6 to include subdividing paddocks and starting to move stock. Since this time the farm has continued to evolve its management style until now where the primary driver for the farm is to use the stock to maximise carbon and nutrient cycling across the farm.
Alex explained:
I had thought that the moment that we started putting in fencing, subdividing, moving stock and going into taller covers and rotational grazing that we could balance saturations of key nutrients and achieve a system where no inputs were required. We’ve built organic matter and are growing pasture, but the system needs to be continuously managed and adapted to try and achieve that balance. I now regard grazing as an art form.
The event started with a session in the barn to understand the evolution of the system and the key principles that the farm uses to drive performance. A key driver over the last couple of years for Alex has been understanding total nutrition and the ability to balance nutrients to enable optimal soil and biological health. This has involved implementing in depth soil analysis to understand the balance of key nutrients within the soil and intensive observation of plant and animal performance to start to understand how they are working together. This has included a focus on calcium as the driver for improving structure, oxygen levels in the soil, grass production and carbon cycling.
The whole farm is set up for total nutrition. We are trying to get the biology working to grow high Brix grazing grass to feed to stock, to sell nutrient dense meats and other products into the local market.
The farm sells honey, eggs, and beef locally where the ability to connect the farm with the produce is valuable and helps to cement the farm as part of the local community and allowing them to identify with the produce and where it comes from.
Alex has adapted his grazing system to encourage more diversity in the leys and to graze taller residuals. He sees far greater value in the hoof impact through trampling than the grazing; when the animals are put into taller covers, they graze the plants higher up and don’t graze the base of the plant, which leads to the carbon rich material being returned to the soil, cycling that carbon to feed the biology. The intensiveness of movement of the stock helps to get the carbon back down into the soil. The tightness of grazing takes away selection of grass.
The first field that we went to see has been used as an experimental field to look at species mixes. Alex researched different grass mixes and has returned to a mix that was common in the 1880s which can be used to improve poorer land. The field had been forage rape previously with lambs grazing the aftermath. The field was then disced and the new ley was broadcast, rolled in and then left. It has just had its third grazing, having been grazed with sheep 8 weeks after sowing to encourage it to tiller in late July. It was then grazed with a mob of about 65-70 cattle to break the parasite window and then had a group of 200 ewes with twin lambs. Every time seeds are sown they are mixed with vermicast, humates and fine lime which encourages biological activity around the seeds and ensures the seed has everything it needs to get going.
Alex really sees the importance of a high seed rate which allows for a thick and vigorous sward but also helps to maximise the value of trampling. He is aiming for 285 plants per m2 and has seen this work well higher up the farm where it is increasing the density of grass and reducing coverage of moss.
The animals have adapted well to the changing system. All the stock are out all year round, there is no housing. Bales are put out for the winter, with the aim being to set up blocks to shift the cattle every two to three days on a self feed basis. The type of cow has changed as the system has evolved; the animals that cope better in this system are slightly smaller framed and carry flesh. The cows need to be at 350kg at 15 months in order to allow them to calve at 2 years old at around 450kg in the middle of April outside. Cattle are weighed and recorded regularly to monitor live weight gain and body condition and FEC tested every 90-100 days to monitor worm burdens. The sheep are also weighed regularly to provide insight into which animals and genetics are coping with the system. The sheep are supplemented with rock salt and minerals depending on the pasture and soil analysis.
It wouldn’t be a soil farmer walk without a group of farmers standing over a soil pit and looking at the impact of the management changes on the soil. Alex has seen changes in soil health, since making the early transition to rotational grazing, however over the last couple of years has been focussing on enabling the biology to thrive and optimising nutrient cycling and the interaction between the soil and the plant roots. As such, two key assessment methods have been useful to show progress which have been the penetrometer and Brix assessments.
I started to get really excited about Brix readings a few years ago, and then really clocked onto it last year. I realised that the taller the plant got the Brix reading grew and grew, we started with 3’s and 4’s, as the covers got to boot stage readings got to 9’s and 10’s which was really exciting. This year, the penetrometer has been a useful tool, the pressure readings had been 250’s and 300 PSI and now we are down to 150, and I think that once we have psi’s of 150 then we are getting oxygen into the soil. We can send soil off to the lab for analysis, but how the soil is structured is a reflection of our management.
If we find fields that are compacted, I’ll skip them and give them 120 days rest rather than 60 days. We have stopped treating the whole farm as one block and looked at what the field needs and how we can optimise root architecture and plant diversity. Its important to us that every grazing experience is positive. We want to get to the point where we don’t need to apply anything, although we aren’t there yet. I’m not totally against applying anything, we need energy in the system and if the soils are tight, then we aren’t at optimal soil function, but the aim is to get to the point where we can target nutrition based on soil and plant need
Due to the nature of the farm and that 85% of the farm is hill areas, a key challenge for Alex has been to manage these areas in a way which can control the bracken ingress. He has been managing these areas in order to build capacity higher up, so that the in bye ground can be managed in a way to provide longer recovery periods.
If I don’t keep enough stock to get on top of the bracken, I will lose the whole farm to it. We only have 8-10 weeks to influence on that plant when it is above the ground, the other part of the year it is below the ground. We have implemented a grazing system which is intensively extensive, really hard hitting when we are there – in the summertime we are moving cattle 4 times per day, but then really long recovery periods. Which allows us to knock the top cover of the plant back but not doing enough to impact the biology and chemistry of the plant – which is why we have just brought pigs onto the farm.
Where this has been implemented, the results have been remarkable. Where the bracken has been managed in this way, the pasture regrowth has been diverse – clovers, vetches and grasses alongside yarrow and red clover are now starting to emerge due to the management system. Although bracken in a challenge, Alex also sees the benefits of it when it is controlled as it is mobilising a lot of potassium around the system which can then be used to support the pasture regrowth. The management of these areas is crucial, where extensive management is leading to the development of these bracken areas,
The base geology between our unimproved and improved land is exactly the same, so the potential to increase output on that land is vast. The more I think about it, the more I think that soils don’t want to be extensively managed, they want to be intensively managed with long recovery periods. We produce a lot of disturbance and then get off it to let it recover.
The group then went to look at the pigs, the new tool in the bracken control strategy! The aim with the pigs is that their rooting activity will help to chew the roots of the bracken up and add manure to aid nutrient cycling. Following the pigs activity the area will then have seed broadcast to increase forage production. The pigs will also be moved into higher areas to help with the bracken control.
The final stop on the walk was at some slightly higher country. The field had been soil sampled and the results had shown good levels of organic matter but suppressed levels of biological activity. As such, Alex is conducting some trials looking at the efficacy of spreading fine lime as a way to improve the calcium content of the soil and enhance the biological activity. Analysis shows that there is most compaction on the farm in the in bye fields, higher up there is less compaction but lower pH’s and less biological activity; as such if we can grow more feed higher up then less forage is required. The farm is using half as much feed as they used to since transitioning to the system. The grass used to be very thatch dominated but there is now an increase in clovers and plantains starting to appear.
Alex explained his change in thinking to manage for what you want rather than what you want to control.
I was so transfixed about managing bracken, I forgot to manage the grass. So by managing the grass, I build the quality nutrition and manage the soils to get the system working, then the pastoral density comes and will deal with the bracken.
To finish the walk questions turned to what next? Alex has spent the last 6 years gathering data, digging holes and persisting to pull it all together. So for the future, he thinks that the big changes have been done, its more about being observational and tweaking the system to optimise biology.
Grass is the most undervalued crop and so we are starting to put it in through the introduction of the new leys. We aren’t carrying more livestock but we are spending a lot less money. Its taken me 10 years to understand how to manage this ground. The failures have been too high- to learn about this we have to get some of it wrong, I’ve never had a year yet where we have got everything right but that is how we learn. Now its time to deliver what we know will work and to drive that system we need nutrition. We’ve been funded to experiment and now the system has to deliver.
Our sincere thanks to the Alex and the team at Rotmell for a fascinating afternoon that gave everyone plenty to think about.
The inaugural Dung Beetle Conference took place in June 2024 at Yeo Valley Holt Farm in Bristol – a collaboration that puts this tiny beast on the farm vet agenda.
Written by Rob Howe
It would have seemed a far-fetched idea a few years ago, a two-day conference about dung beetles attended by farmers, vets, policymakers and schoolchildren. Yet in June this year, we pulled it off, with huge thanks to Dr Hannah Jones (Farm Carbon Toolkit) and Rob Howe (BCVA, COWS, Vet Sustain), together with event sponsors, First Milk, Yeo Valley, Techion, Micron Agritech and Duggan Veterinary Supplies.
Hannah and Rob share mindsets around regenerative farming topics and how dung beetles should fit into all farmer’s thoughts and practices. Researchers have previously held Dung Fauna conferences, but these have been largely academic. This re-imagining of those events held by Richard Wall, Bryony Sands, Sarah Beynon and others, aimed to focus on biodiverse farming and integrated parasite management (IPM), which has been the focus of Rob’s work both in practice, in research and in his Nuffield Scholarship.
Conference Write-Up
The conference was opened by Sarah Beynon who spoke passionately about dung beetles and of her seminal work calculating their positive £367m of beneficial financial impact every year to UK cattle farms. Darren Mann, widely considered the gospel on dung beetles, wowed the audience with his own passion and bluntly hilarious style! We then heard of the impact parasiticides have in the environment and the degradation times of dung pats, as well as new research linking their abundance and diversity to soil health parameters from Bryony Sands, video-linked from the USA.
Organisers found it rewarding to see all the decades of superb work from so many inspiring people, brought together and shared with those that need to know it most – farmers and vets.
There is an impressive body of work now that led to my own efforts in proving there is an alternative approach – Integrated Parasite Management (IPM)
Rob Howe, BCVA, COWS, Vet Sustain
Rob Howe spoke on the importance of IPM, and the vital role of the vet, along with a vision for animal health tied in with this new approach. I then had the privilege of handing over to a wide array of experts in their fields to talk on the individual subjects and strategies that make up IPM, including species diversity, farming biodiverse, breeding for resilience, the role of trees, pasture management, soils and FEC testing. It was a ram-packed day punctuated at lunch by a dung safari led brilliantly by Darren Mann.
The conference also offered an opportunity to see demonstrations of key providers of in-house FEC testing by FECPAK, Micron, and Ovacyte who all attended and sponsored the event
Day Two started in the mature agroforestry system, and a dung beetle hunt was led by Claire Whittle, with input from many others including Sally-Ann Spence and Lindsay Whistance, whose work on the value of trees for livestock, needs much more airtime.
Over the two days we got to hear from so many great speakers all linking dung beetles to wider biodiversity including birds, a fantastic project on Dartmoor and how equine and small animal vets and owners are grasping the opportunity to have similar positive impact in their respective fields.
The responsible use of parasiticides
The conference ended with a workshop supported by BCVA, COWS and Vet Sustain. The workshop opened with a short “scene setting” presentation from the VMD with an overview of the current regulatory framework for veterinary medicines in the UK. The discussion groups focused on the issues around responsible prescribing and parasiticide use and identifying workable solutions and associated actions to drive much-needed positive change to promote the responsible use of parasiticides.
BCVA has been working hard behind the scenes for some years to influence progressive policy change in this area. BCVA’s policy on parasite control was launched by Sally Wilson in 2021, following Rob Howe’s IPM workshop and introduction to the power of dung beetles at Congress. BCVA has since been involved in wider collaborative discussions with the VMD and additional stakeholder organisations and recently worked with BVA on parallel activities to make progress on this important subject.
Key asks, actions & outcomes from the workshop
Farmers, farm advisors and farm vets all fed back in the workshops, offering a range of ideas, with the following common themes:
Education
To promote IPM as a more sustainable way to approach the use of parasiticides, all groups cited novel education and training as essential – specifically, for practising vets but also in vet schools and agricultural colleges.
A strong desire for everyone to get on board with a “new narrative” on display at the conference, reaching beyond IPM, producing food good for humans, the planet and of course animals.
Peer-to-peer learning opportunities were valued highly by everyone when it came to shifting farming practices, with many on display at the conference.
Funding
It was highlighted that opportunities for IPM to be funded within the SFI-type schemes, as it is in the arable sector, would be beneficial.
A general fund for (farms’) innovative ideas rather than prescriptive lists. Excellent examples might be EID/ Handling/Weighing facilities for DLWG and helping IPM & targeted selective treatments.
A cross-industry fund created to facilitate the rollout of IPM; training and tools for delivery and recording.
Monitoring
Collecting baseline figures on top-level use for the livestock sector would enable monitoring of progress, similar to those seen with antibiotics. The VMD were present, and we hope in time will help deliver this.
The same applies to the farm level where benchmarking could help drive change. This may be more likely to come from the industry itself.
Policy & Governance
Advertising of parasiticides should not be targeted at end users (across spp)
POM-V status could ensure this, but so could a legal change in advertising rules for parasiticides.
IPM should come into landscape recovery, and eventually as standard everywhere
A desire for support for vaccines such as louping ill to be available and others developed
More robust environmental assessments (small animals particularly) and enforcements of product advisory wording across species.
Communication
The need for improved communication between the entire farm team and advisors
Improved communication between vets and SQPs would be ideal. An app to facilitate IPM may be able to help achieve this.
Landscape approaches
Commons health plans and or landscape health plans (look outside the farm gate).
Industry support, facilitation & incentives
Milk buyers are already involved in a positive way. Great examples here at the conference with First Milk and Yeo Valley sponsoring and encouraging positive changes.
Others including M&S support farms to look at parasite control through an IPM lens and Muller leading the way in starting to measure usage.
Timeline for Change
Sentiment for action was positive, with 5 years set as a target, since this movement is already happening as evidenced at the conference, and people are aware, so major change could happen quite quickly.
Get in touch and join the movement
The conference concluded with a commitment to work across the sector to progress these key actions. We would like to hear from anyone keen to help achieve these aims and or be involved in the next one. Please contact Rob_ [email protected] or [email protected].
Conference Acknowledgements
This conference built on a brilliant legacy of research, and brought together farmers, vets, soil experts, entomologists, researchers, industry and public, to celebrate the great work that is going on, but also to shape future policy and regulation. In the interest of brevity, it hasn’t been possible to acknowledge every speaker, contributor or supporter of this event, but the organisers would like to thank everyone who helped make this happen and also show appreciation to all those who have worked for some time in this important area to advance our profession’s understanding. And finally, a huge thank you to all the event sponsors – Yeo Valley, First Milk, Techion, Micron Agritech and Duggan Veterinary Supplies – without whom we could not have made this day happen.
Conference Reflections from a Vet Andy Adler – Farm Carbon Toolkit – Vet Perspectives
As a vet who has been out of clinical work for a while, I turned up to the Dung Beetle Conference 2024 due to my role in one of the sponsoring companies, Farm Carbon Toolkit. I had been aware of dung beetles and integrated parasite management (IPM), but I had little knowledge and no experience discussing IPM with farmers.
I found a place with positive energy and a diversity of farmers, vets, and industry professionals united in the need to identify how to support ecology in farming while supporting food production. The mix of sponsors from First Milk, Yeo Valley and Farm Carbon Toolkit meant that the industry was well represented and led the conversation on how to get to a farming system with a positive impact on the environment and nature.
Shifting baselines (Masashi Soga, 2018) come to mind for me. Farmers there described how dung pats would disappear within 24 hours as multiple species of dung beetles eat, bury and process the dung. I still find this expectation ‘unbelievable’; however, I accept that this is due to my shifted baseline of expectation. I also realised that as vets, we must deal with the conflict of interest between animal needs and the owner’s ability. Now, we have to deal with disputes between animal needs, nature needs and the owner’s ability to understand how best they can balance off competing demands.
I left after two days of interactive talks and an exploratory field safari, identifying dung beetles and understanding their abundance within healthy pats. My mind was opened. I now look in cow pats and understand how few beetles are on some farms.
The following questions (and more!) have sat with me since.
– How can we understand our shifted baseline and rebalance it? – How do vets deal with an additional conflict of interest? – Can IPM become a veterinary campaign similar to the Mastitis Plan or Health Feet Program?
I would highly recommend that farm vets think about dung beetles and their moral and ethical responsibilities towards the environment, animal welfare, and owners’ needs.
Now in its second year, the annual Carbon Farmer of the Year competition is organised by the Farm Carbon Toolkit and generously sponsored by HSBC Agriculture UK. The competition aims to find farmers and growers who are engaged with–and passionate about–reducing their business’s climate impact through changing management practices to reduce greenhouse gas (GHG) emissions.
Andrew Brewer was awarded the Carbon Farmer of the Year Award for 2024, presented by Steve Dunkley, our sponsor from HSBC Agriculture (seen in the picture below).
Andrew Brewer, Winner of the Carbon Farmer of the Year Award for 2024 presented by Steve Dunkley, HSBC Agriculture UK
Andrew is part of the Farm Net Zero project and low GHG farming has been a top priority for him and his farm for a number of years. He manages 500 Jersey X dairy cows across his 400 Ha farm in Fraddon, Cornwall. He stood out to the judges for his understanding and application of a range of practices to enable his pasture-based dairy farm to remove atmospheric carbon into soil, trees, and hedges, while simultaneously minimising farm GHG emissions by focusing on maximising forage intake for his dairy cows and minimising inclusion of supplementary concentrate feeds. Andrew also selectively breeds his cows to work well within his pasture-based system. There is an opportunity to tour his farm during a farm walk he is hosting on November 8th.
The other two finalists, Tom Burge and Jason Mitchell were praised for their continued efforts to mitigate greenhouse gas emissions in their businesses. The finalists awards were presented by David Cope, Head of Sustainability at the Duchy of Cornwall who was also on the panel of judges (seen below). Tom Burge, who featured in the mob grazing workshop has done fantastic work cultivating a low input grazing system which has seen vast improvements in his grass quality and sequestration potential.
Similarly, Jason Mitchell is a Director of Greenville Dairies Ltd based in Newton Stewart, Northern Ireland. He has also been recognised for his continued effort to farm in a low carbon management system. At Greenville Dairies they have reduced emissions from their 850 strong dairy herd, largely through the application of genomics leading to greater feed efficiency alongside the development of a significant Anaerobic Digestion facility which sees them now taking in food waste alongside utilisation of cow manure to produce electricity, liquid natural gas (LNG) and digestate. Electricity and LNG are sold to the grid and to Companies such as Lakeland Dairies (their customer for their milk).

Competition judges, Steve Dunkley (HSBC UK), David Cope (Head of Sustainability at Duchy of Cornwall), and Liz Bowles (CEO Farm Carbon Toolkit) were very impressed with the commitment and innovation shown by all the finalists in identifying sources of GHG emissions on their farms and developing strategies to both reduce emissions and increase the rate of carbon removal into soils and non-crop biomass.
Liz Bowles, Chief Executive Officer at Farm Carbon Toolkit, says:
Once again, the Carbon Farmer of the Year competition has identified some truly inspirational farmers. All our finalists have made great strides in reducing business reliance on fossil fuels through changes to their farming practices and careful soil management to reduce GHG emissions and sequester carbon.
It was particularly positive to see a dairy farm winning this year’s competition, given that dairy farming is often in the media spotlight for its adverse environmental impact. We are looking forward to showcasing the many effective ways that our finalists are reducing on-farm emissions and increasing carbon storage for others to see at free farm walks over the coming months. Watch this space!
Steve Dunkley, HSBC UK Agriculture, says:
HSBC UK Agriculture is pleased to support the 2024 Carbon Farmer of the Year competition. The quality of entries has been superb and hugely inspiring. As a business, we’re very keen to support the agriculture industry in transitioning towards net zero. While that will take many forms, we have the ambition to help farmers fund investment in the new practices and technologies needed to evolve.
The Carbon Farmer of the Year competition is a great way of showcasing how farmers are already achieving these changes and encouraging others to follow their lead
The FCT field day was an event to shine a light on the sustainable solutions benefiting farmers economically, socially and environmentally. The focus was on mixed agricultural systems, as well as celebrating those who are doing the most to reduce greenhouse gas emissions and sequester carbon into their soils.
On the 25th September 2024, our Annual Field Day brought together farmers from all over the country, including the winners of our past FCT Soil and Carbon Farmer of the Year competitions, to hear about the exciting developments in sustainable agriculture. In addition, we were grateful to HSBC UK Agriculture who helped sponsor the Carbon Farmer of the Year Competition and to all our supporters of the Annual Field Day – Cross Compliance Solutions, First Milk, Shearwell, Velcourt and Yeo Valley.
The event was held at Boycefield Farm in Dilwyn, courtesy of Billy Lewis, Soil Farmer of the year (2022) and the Lewis family. The day was a grey one with a few showers but did not dampen any spirits or the curiosity of the farmers that enjoyed the day!
Our delegates arrived ready for a 10am start which was officially kicked off by a welcome from FCT CEO Liz Bowles and an introduction to the farm by host Billy Lewis.
Opening comments by Billy Lewis to all the guests
Billy Lewis – Our host and 2022 Soil Farmer of the Year talking about how the farms’ approach of integrating livestock and herbal leys into a previously intensive arable system has rejuvenated soil health, drastically reduced fertiliser and feed inputs, whilst boosting profitability. Billy also mentioned the challenges his farm has been facing, with the changing climate and consistently wet weather proving to be high on the list.
We enjoyed a circuit of the farm to join workshops on subjects including adapting arable rotations to build fertility and resilience in a changing climate, mob grazing and the importance of soil testing. We heard about developments that have been made on Boycefield farm, as well as from farmers implementing similar systems across the country.
We have captured a snapshot of the workshops below:
Soil clinic – chaired by Becky Wilson (FCT)
We heard from our very own Becky Wilson and Niels Corfield, a regenerative agriculture advisor.
Becky standing in the soil pit explaining the benefits of upkeeping healthy soil to the group
Niels and Becky focussed on firstly, and most importantly, how the health of the soil is crucial to any agricultural system. Having a deeper understanding of what to look for within the soil aids farmers in assessing their own soils and tailoring their systems to increase soil health and fertility.
Becky brought us around the freshly dug soil pit to demonstrate the levels of compaction that occur at different depths. Highlighting the importance of less dense, yet stable soil in the top layer so that root growth of grasses and herbal leys are not hindered by increased soil density. It was pointed out that Billy Lewis’s mob grazing style was contributing to the meadow’s low soil density and therefore thriving grass system. As the stock is moved frequently, there is little time to compact the soil by trampling. Becky also highlighted the importance of earthworms for soil health. Earthworms are a key indicator of good soil health as they provide a multitude of benefits. Their burrowing increases spaces within the top layers of the soil which allow in water and air which promotes root growth for pastures through reduced compaction. Additionally, as Becky mentioned, their powers of nutrient cycling cannot be understated. Earthworms feed on organic matter which is excreted into plant available nutrients, speeding up pasture growth.
After Becky’s talk on soil qualities Niels took over to discuss a few practical methods (without the use of fancy gadgets) farmers can use to assess their soil health. With only the use of a spade and an inspection of what’s going on below the grass you can tell a lot about the soil. Niels encouraged the guests to go out into their fields and start to collect samples. He demonstrated the method of collecting a core sample by inserting a spade to a depth of around 30 cm on three sides and used the last side as a hinge to lever up a block of soil to inspect. Once the sample was out of the ground, he highlighted the relative ease of which the soil broke up as well as pointing out the abundance of earthworms, noting that this isn’t the case for a lot of agricultural soils.

Livestock and mob grazing – chaired by Stefan Marks (FCT)
In this talk we heard from Tom Burge, an upland beef and sheep farmer, Billy Lewis, the host farmer, as well as Dan Smith, a farm manager running a commercial, net zero livestock farm alongside being a facilitator at the Herefordshire Rural Hub. They talked about their experiences with mob grazing, grass quality and the lessons they have learned experimenting with grazing systems.

In this session, Billy, Tom, and Dan discussed the benefits as well as the challenges involved with mob grazing while drawing on their shared experience of experimenting with this type of grazing system.
Tom Burge is a 4th generation farmer, owning an upland grazing farm in North Exmoor rearing over 1,000 Romney X ewes and 500 Scottish Blackface ewes. As well as 100 Angus suckler cows. After setting aside a 150 acre field trial with the aim of reducing fertiliser application, he began experimenting with mob grazing. He found that moving stock regularly (in his case every 2-3 days) and long resting periods resulted in improved grass quality and increased grass growth. All the panellists concurred that long resting periods for the grassland is crucial for increased grass quality and plant diversity which leads to more resilient grasslands.
In terms of economics, all the panellists agreed that the switch to mob grazing resulted in higher live weights and milk yields from their cattle and sheep. However, it was interesting to hear that these yield increases were marginal compared to the reduction in costs which resulted from the change of system. Dan found that within his new system, he could keep sheep outside all year round, including during lambing. He noticed that less bacterial infections and instances of pneumonia were occurring when he made these changes. Billy also noted the lack of fly related infections on his cattle on his mob grazing system which resulted in lower veterinary costs and better welfare. Although Billy still has periods through the winter where cattle are kept inside, these periods have reduced and therefore feed costs have decreased as a result. All the panellists concluded that optimising for a low input system was of great benefit to not only their pockets but the health of the stock as well.
An insightful question came from one of the listeners of the talk, who asked; how do you measure the changes in pasture performance? All three panellists admitted that they didn’t formally measure or record grass growth or quality of. Through anecdotal evidence and multiple decades of experience growing grass and farming on their respective farms they could see the difference in the quality of their grass which has translated into the quality of their stock and produce. Dan Smith added to this, highlighting that the preferred measure of performance is through financial gains, where all three of panellists have found a financial benefit.
A second question was fielded around the time consuming nature of mob grazing after Billy mentioned his rotations may only last 6-12 hours on some of his more intensely grazed meadows. He has found that frequent livestock movement isn’t as unmanageable as one might think. He proceeded to demonstrate the ease of which he can move electric fencing hexagonal fence posts (as seen in the picture below). These structures rotate along the ground as Billy moves the end of the fence, saving time by not having to take out every fence pole and place it in a different location in the field. Through experience, Billy often decides when to move his cattle by eye and knows that a system that incorporates flexibility works best for him. This certainly helps with the weather challenges that the three panellists agreed was a main limiting factor to their system. Droughts and periods of heavy rain (which were wonderfully demonstrated throughout the day) are challenges where flexibility is a crucial mitigator. Billy with his free moving electric fence pointed out that he can avoid waterlogged areas in order to protect the soil and grassland from trampling which is even more of a danger in wet conditions.

Arable/ Herbal Leys – chaired by Tilly Kimble-Wilde
We heard from Angus Gowthorpe (mixed farmer and Soil Farmer of the Year 2018 finalist), Edward Gent (Cambridge arable farmer who has been no-till for 16 years) and FCT’s Anthony Ellis (FCT farm carbon and soil advisor and mixed farmer). The talk focussed on their experiences with diversifying arable rotations, sometimes with herbal leys as well as their different approaches to grazing these areas.

Angus Gowthorpe, who manages a mixed farm in North Yorkshire, spoke about his transition from conventional to regenerative farming and how herbal leys have played a crucial role in this shift. By integrating a mix of species into his rotation, including deep-rooting herbs such as chicory and plantain, he has seen significant improvements in soil structure and organic matter. Angus highlighted how the diversity of plant species in the herbal leys helps build resilience in the system, reducing reliance on chemical inputs. He highlighted how grazing these leys with his cattle further stimulates root growth, enhancing the biology of the soil, contributing to a more productive and resilient farm ecosystem. The sentiments of this approach were echoed by both Edward and Anthony who had implemented similar systems.
Afternoon Sessions: The economic and climate impact of ‘regen’
Following lunch, we moved into a panel discussion Chaired by James Daniel with presentations from Anthony Ellis (FCT), Angus Gowthorpe, Tom Burge & Nick Down (Velcourt Farming Ltd).
James Daniel – Founder of Precision Grazing, whose primary objective is to optimise performance from pasture, James works across the UK helping farmers to implement and manage their grazing systems alongside ensuring family quality of life for farmers.
Angus Gowthorpe – mixed farmer and Soil Farmer of the Year 2018 finalist. Angus has been at the forefront of the regenerative transition in the UK and continues to push the envelope on what defines a sustainable farming system.
Tom Burge – Upland beef and sheep farmer whose move to a regenerative, grazing-based system has helped to eliminate inputs and transform the finances on his challenging Exmoor farm
Nick Down – Nick is the Head of Sustainability for Velcourt Ltd. Velcourt directly manages 57,000 hectares and provides advice in both the arable and dairy sectors across the UK. Nick oversees the farming operation of the Yattendon Estate in West Berkshire. The estate is going through a transition to a more sustainable farming system, incorporating more space for nature and enhancing carbon sequestration under an ambitious environmental delivery program. The farm is also a LEAF demonstration farm.
First each of the panel members presented an overview of their farming system, the regenerative practices they’ve employed and the subsequent improvements this has made to their business carbon footprint, resilience and profitability.
Angus sharing with us the financial benefits of his regen system
Angus shared with us a side by side comparison of his arable operations between his previous conventional system and his current low-input regen system for winter wheat production. From this slide it is obvious to see what financial benefits arise from converting to a regen system. Firstly, his in-field operations have reduced from four operations to only using direct drilling on his fields. This saves him a total of £142 per hectare. Additionally, a reduction of his fertiliser inputs saved his business £189 per hectare. Through soil analysis he found that his past applications of P and K were superfluous to crop requirements. He has also reduced reliance on fungicides and plant growth regulators by £103/ha. The reduction in inputs has given Angus an ability to withstand a lower yield without reduction in enterprise margin. At current prices he calculated that this was equivalent to around 2.3 tonnes/ ha or around a 30% reduction in yield.
A perspective of the greenhouse gas emissions reductions and financial benefits of regenerative agriculture from livestock farming came from Tom Burge who kindly shared his numbers before and after adopting his new farming strategy.
Tom Burge’s projections on how his emissions will change while continuing on his regenerative farming journey.
From starting his journey in 2017, he has eliminated use of fertiliser on his pastures, significantly reduced reliance on external feed and fuel, as well as reduced the number of hours of manhours worked on his farm. This has all translated into a steady reduction of on-farm emissions (expressed as kgCO2e per kg live weight of his stock). Due to implementing mob grazing strategies, pasture growth has increased by 0.9 tonnes of dry matter per hectare, displacing 36 tonnes of fertiliser and 72 tonnes of feed between 2017 and 2022. On top of the 1.66kgCO2e per kg of live weight, this has saved Tom’s business financially, to a tune of £24,000 per year. By 2022, Tom realised that the increasing cost of inputs outweighed the potential added value of his outputs, making these inputs un-economical to use.
Breakout workshops on field trials, weatherproof farming and composting

Composting: Billy Lewis
Billy Lewis showed us his farm-yard manure composting process. After buying a windrow compost turner second hand, Billy is able to easily turn the compost pile to aerate it. Ensuring good air flow is key to creating compost, as aerobic microorganisms feed on the organic components and convert them into a nutrient rich soil amendment. Composts are much more stable than farm yard manures, providing a more consistent and slow release of nutrients, therefore, benefitting soil health in the longer term. This slow release enhances soil health and pasture growth by reducing the amount of leaching and volatilisation that occurs. Billy explained how he adds different components to his compost depending on what is available, such as wood chips and apple peel from a nearby orchard.
Research Trials: Hannah Jones
Hannah Jones (Senior Soil and Carbon Advisor with FCT) led an insightful discussion on effectively planning and conducting field trials in a scientifically robust yet practical way. She began by explaining the essentials of multi-year farm trials, covering aspects like choosing crop options for trial strips, combining various tests within one field, and structuring controls to minimise the effects of natural variations on trial results.
A major focus was on understanding how different factors can influence outcomes and the importance of controls. For instance, in a trial introducing beans into crop rotation, it’s crucial to have both fertilised and unfertilised areas to determine if observed benefits are due to the nitrogen contribution from beans, the fertiliser itself, or just field characteristics. In livestock research, increasing population size reduces the impact of natural variation (e.g. individual susceptibility to disease), thereby making the data more statistically reliable. Randomly assigning animals to control and trial groups is also key, as it prevents biases that could affect outcomes; for example, having the first ewes going through the hurdle enter one field and the latter half go into another could unintentionally separate the flock by skittish and lazy animals, skewing results because they have different temperaments.
Hannah also shared ideas and trials setups which some of the attending farmers were considering. The conversation highlighted the value of data sharing—each farm is unique, but insights from one trial can benefit many. By participating in groups like the Innovate funded Nitrogen Climate Smart agriculture (NCS) project, farmers can connect, share findings, and collaborate on new practices. FCT advisors are available to help with planning and can connect participants with like-minded farmers to optimise trial efforts.
Weatherproof Farming: Niels Corfield
Niels delivered a presentation which demonstrated to us the importance of improving soil health for sustainable farming. Niels Corfield is a farm advisor interested in regenerative farms and landscapes.
He shared video examples of how compacted soils, often mistakenly thought to be saturated due to standing water, were actually preventing deeper water infiltration and leaving dry soil underneath. Healthy soil, with proper porosity, was shown to allow water to penetrate, “banking” moisture for dry periods, which is crucial for crop resilience in hot summers.
Niels made a case for weatherproofing farms to both rain and drought through a mixture of practices including soil management, mechanical interventions e.g sub soiling, mineral, and biological interventions. We looked at some of these in detail. A key takeaway was that root health is central to improving soil structure, and managing grazing or cropping practices to encourage root mass and density is a fundamental part of improving soil resilience and health.
The evidence presented showed that a move away from set stocking and changes in pasture management was able to extend grazing seasons, reduce the need for winter housing, and boost grass production. Data from various drought years showed how drought severely impacted grass growth across the UK. However, farms with better-managed soil saw increased productivity due to better water retention, emphasising the benefits of improving soil structure and retaining water during wet seasons for use during dry spells.
We were left with the idea that land provides honest feedback which can be seen and acted upon: It reveals the effectiveness of farming practices through direct observation and we were encouraged to inspect the land regularly ourselves in real-time with a range of tests, rather than solely relying on lab results.
Carbon Farmer of the Year 2024
This very interesting and insightful field day concluded with the presentation of carbon farmer of the year. It is the second year of the competition and is awarded to a farmer who is engaged with and passionate about reducing their business’s climate impact. The award focuses not only on changing management practices to reduce greenhouse gas emissions but also on understanding and enhancing carbon storage in farmland. We were delighted to be joined by the three finalists. Andrew Brewer was awarded the Carbon Farmer of the Year Award for 2024, presented by Steve Dunkley, our sponsor from HSBC Agriculture (seen in the picture below). Andrew is part of the Farm Net Zero project and low GHG farming has been a top priority for him and his farm for a number of years. He manages 500 Jersey X dairy cows across his 400 Ha farm in Fraddon, Cornwall. He stood out to the judges for his understanding and application of a range of practices to enable his pasture-based dairy farm to remove atmospheric carbon into soil, trees, and hedges, while simultaneously minimising farm GHG emissions by focusing on maximising forage intake for his dairy cows and minimising inclusion of supplementary concentrate feeds. Andrew also selectively breeds his cows to work well within his pasture-based system. There is an opportunity to tour his farm during a farm walk he is hosting on November 8th.

The other two finalists, Tom Burge and Jason Mitchell were praised for their continued efforts to mitigate greenhouse gas emissions in their businesses. The finalists awards were presented by David Cope, Head of sustainability at the Duchy of Cornwall who was also on the panel of judges (seen below). Tom Burge, who featured in the mob grazing workshop has done fantastic work cultivating a low input grazing system which has seen vast improvements in his grass quality and sequestration potential.
Similarly, Jason Mitchell is a Director of Greenville Dairies Ltd based in Newton Stewart, Northern Ireland. He has also been recognised for his continued effort to farm in a low carbon management system. At Greenville Dairies they have reduced emissions from their 850 strong dairy herd, largely through the application of genomics leading to greater feed efficiency alongside the development of a significant Anaerobic Digestion facility which sees them now taking in food waste alongside utilisation of cow manure to produce electricity, liquid natural gas (LNG) and digestate. Electricity and LNG are sold to the grid and to Companies such as Lakeland Dairies (their customer for their milk).

Dairy is often in the spotlight in terms of its environmental impact. Whether it be focussed on slurry management, methane emissions from animals, or soil loss and run off from maize crops, dairy is often an easy target. However, there are numerous farmers and projects who are showcasing that this doesn’t need to be the case, and there are positive steps that can be taken.
When approaching Groundswell this year, it was one of the things that we wanted to highlight. We are very lucky to work with some really forward-thinking organisations and farmers that we wanted to highlight at this national event. So we submitted our session “Can Milk be green?” to try and understand some key questions.
These were:
How do we quantify the importance of regenerative dairy systems when the current metrics are solely focused on reducing emissions intensity/litre?
How do we accurately represent the contribution that regenerative dairy systems are providing to carbon sequestration, biodiversity and resilient landscapes?
How do we do this in a cost-effective way which provides reassurance to processors and consumers that milk can be green?
How do we support farmers in that transition?
We had a fantastic panel of speakers which included farmers who were making changes and processors who were supporting both data collection, evidence building and industry communication.
Tom White from Yeo Valley introduced the session and highlighted the ability for grass-based dairy systems to deliver on a wide range of environmental benefits. The key areas of importance were around how we gather good data, collaborate and support our farmers to be able to deliver the changes on-farm. Tom focussed on the importance of diversity, including diversity in our pastures, rotations and management systems to deliver on a range of environmental impacts.
Andrew Brewer from Ennis Barton farm in Cornwall provided some insights into the trials that he has been involved with on his farm as part of the Farm Net Zero project. Trialling herbal leys and their impact on cow health and rumination, soil recovery after potatoes and cover crops have all provided useful tools to build soil heath and reduce emissions.
Will Mayor from Yeo Valley farms spoke about how by using their experiences with the beef animals they have adapted a system that works for their dairy cows. Implementing next-level grazing has allowed them to increase covers, remove the topper from the system and maintain milk quality and pasture utilisation, alongside soil health and carbon sequestration.
Lucy Noad from Woodhouse Farms shared her story in terms of her transition from a more conventional dairy farm over the last few years. Lucy spoke about the need to support farmers in the transition and also to ensure that the way we communicate engages farmers to understand the relevance of practical solutions for them.
Mark Brooking from First Milk concluded the session highlighting some of the ways that First Milk are supporting their farmers to make the transition to more regenerative practices. Farmers are supported through incentives to implement rotational grazing, species diversity and minimal cultivation in order to demonstrate an uplift in soil health, sequestration, biodiversity and water quality. Data is being collected on the impact of these changes to provide confidence in the potential for their members to deliver solutions.
It was an inspiring session which provided real life examples that show the positive steps that are taking place to provide data, collaborate and support farmers. Although our soil project with Yeo Valley is in the interim years before we retest soils, it was great to hear some of the practices taking place and the production and resilience benefits that the farmers are seeing now irrespective of soil carbon sequestration.
So can milk be green? The answer was a resounding yes!
Watch a replay of this webinar held on the 11th September 2024 where representatives of the three major farm carbon calculators shared more details of the work they are doing together: Work to support UK agriculture to measure GHG emissions using the most up-to-date and accurate tools possible, harmonising the methodologies and outputs of their carbon calculation tools.
We received a great list of questions during the webinar event and teams from the various calculators will look to address those queries in due course.
The three major farm carbon calculators featured in the Defra Report Harmonisation of Carbon Accounting Tools for Agriculture – SCF0129 have announced a collaboration by signing a Memorandum of Understanding (MOU), intended to harmonise the methodologies used in calculating the greenhouse gas (GHG) emissions from agriculture.
The three companies are looking forward to their joint work on this major challenge, to fulfil the requirements outlined in the comprehensive Report, compiled by ADAS throughout 2023. It is generally agreed that the overarching goal should be to reduce the overall greenhouse gas emissions from agriculture through resource efficiency improvements, optimising production practices and mitigating environmental impacts.
Liz Bowles, Farm Carbon Toolkit CEO, said:
We are not seeking to reach a point where all three calculators will produce the same answer for any given dataset. As the Defra report put it, “ there is no single ‘right’ answer”. Rather we are striving to make it possible for users to fully understand why different calculators produce different answers.
We plan to align with the Science-Based Targets initiative Forestry Land and Agriculture Guidance (SBTi FLAG) and draft Greenhouse Gas Protocol Land Sector Removals Guidance (GHGp LSRG) through our collaborative actions. This commitment underscores our dedication to maintaining high-quality standards and ensuring environmental sustainability in our operations, and in calculation outputs.
Scott Davies, Agrecalc CEO, said:
It is intended that we agree on a common set of data sources which all three calculators will use. All calculators can go beyond these baseline requirements, and all parties to this MOU will retain their commercial independence. We will also involve the relevant government and other organisations’ teams with our work plan as we develop it.
This collaborative approach supports a joint understanding of industry requirements and advancing consistency in our tools and methodologies. Our goal is collaboration with industry, trade bodies, and fellow calculator providers in the UK and internationally, so that we can actively contribute to the development of more consistent approaches to on-farm carbon calculation.
Richard Profit, Cool Farm Alliance CEO, said:
We are looking forward to this collaboration, as it will help align methodologies where that makes sense and that will especially allow us to look into new areas that require attention. How we then incorporate the new information in our calculators will vary from calculator to calculator as a result of our different base approaches.
We will also ensure that the tools include the latest and most robust scientific findings into their frameworks and roadmaps.
The calculators are seeking that this joint work become the “agreed way” and at some point, become a minimum required standard for all calculators to adopt. The companies will engage in consultations with Defra, Welsh Government, Scottish Government, and Northern Ireland Government to reach a practical and realistic form of ongoing validation of their harmonisation work.
Methodologies or other harmonisation solutions developed as a direct result of the MOU will be published transparently, or will otherwise be made available for others to use.
Although this MOU currently only involves the three major companies in this space, the group is open to other calculators joining the coalition so long as they publicly provide transparency in their Calculator methodologies.
We will be holding a joint webinar on the 11th September 2024 at 1pm – 2pm to share more details of the work we are doing together. Please register here if you would like to join us

The course will take place in Cumbria, with sessions at the University of Cumbria’s Ambleside Campus, at upland farms across the county, and online.
Participants will learn where and how greenhouse gases are emitted, captured and stored on an upland farm. Farm visits and theory sessions will enable a comparison of farming practices and land management options, with climate impact in mind. In-person workshops will build skills and confidence to enable each participant to complete a quantitative farm carbon audit and make practical recommendations for actions towards net zero emissions.
Up to 12 full bursaries, subject to eligibility, are offered by the Foundation for Common Land via their Our Upland Commons project, with details available here.
Farm Carbon Toolkit supported the development of this accredited course for farmers, advisors and new entrants and worked with the University of Cumbria to enable delivery of the course for the first time earlier this year, in Dartmoor. Comments from participants included:
It was really worthwhile and I’ve gained a lot of knowledge and practical skills from attending
Plenty of on-farm, real-world teaching and examples
Becky was a fantastic tutor- incredibly engaging and knowledgeable
Dung beetles are fascinating creatures that play an essential role in breaking down dung, reducing greenhouse gas emissions and providing vital ecosystem services such as improving pastures, conditioning soils, and reducing parasitic burdens on our livestock.
What are the types of dung beetle?
There are three basic groups of dung beetles: dwellers, tunnellers, and rollers. Dwellers live and reproduce within the dung, tunnellers create channels underneath the dung pat pulling dung through the soil and storing within the tunnels to eat and lay their eggs, rollers roll dung balls away and bury them underground.
Where can you find dung beetles?
Dung beetles are found on every continent except Antarctica. Their habitats range from desert to farmland to forest, owing their entire existence to dung from an equally wide range of animals. You’ll find most dung beetles in or around dung pats from herbivores that typically pass undigested plant material as well as liquid. Adult dung beetles tend to feed on the more liquid portion of the dung pat and dung beetle larvae will feed on the more solid portion. Hence, it’s important for the animals depositing dung to have a diet containing lots of fibre.
Dung beetles in the UK
There are around 60 species of dung beetle in the UK belonging to the tunneller and dweller groups – rollers are found in the warmer climate of the southern hemisphere. Some dung beetles are active during the day whereas some fly at night. Just like humans, dung beetles have preference when it comes to sniffing out food (dung). Some prefer dung from specific animals, some prefer dried dung as opposed to fresh and some are even picky when it comes to the location of dung within a field, however, mostly are generalists and will reside in any they can find.
What are the benefits of dung beetles?
It has been suggested that dung beetles can save the cattle industry around £367 million a year.
How?
Firstly, they increase soil nutrients. Fresh dung contains nitrogen, potassium and phosphorous; dung beetles eat, bury, and release these nutrients for the benefit of the surrounding soil biology, improving soil fertility and soil structure through channelling and drawing down organic matter. This can reduce reliance on fertiliser and makes much better use of our manures.
Secondly, dung beetles reduce pasture fouling. When dung isn’t removed from the field, the grass underneath it will die and the grass surrounding it will be unpalatable to livestock. If you scale this up, it removes a huge area for grazing as well as wasting an abundance of nutrients.
Thirdly, dung beetles are excellent at reducing pest flies from the activities of mites which are transported on the beetles’ bodies. The value of these organisms can be identified through reduced parasites on your livestock that ultimately impact milk yield and liveweight gains due to energy expended by the livestock to defend themselves or fight against infection. In both cases, dung beetles reduce survival of flies and parasites through competition of resources.
Why are dung beetle populations in decline?
Unfortunately, despite the benefits of dung beetles, they are in decline due to the intensification of livestock systems – use of pesticides and anthelmintics. During the grazing season, dung pats could be broken down in a matter of days but instead, many lie rotting for a long time (and producing more methane emissions).
How can we encourage dung beetle populations?
Provision of dung is vital. If we’re able to outwinter even a fraction of our stock it provides a food resource all year round, attracting a more diverse array of dung beetle species.
Feeding livestock a more fibrous diet i.e. moving away from a grain-based diet can also help as it’s important to provide that partially undigested fibrous material.
Finally, long-acting anthelmintics can cause catastrophic loss of dung beetle populations. With veterinary support, frequent weighing of livestock and spot-treating animals offers a more sustainable way of reducing anthelmintic use, reducing the wormer-resistance in intestinal parasites, and protecting dung beetle populations.
How can we find out more about dung beetles?
There’s a wealth of information online about dung beetles, but to really get down to the detail, Farm Carbon Toolkit is holding a two-day conference, in partnership with leading vets, dairy cooperative First Milk and Somersetdairy company Yeo Valley, on Tuesday 11 and Wednesday 12 June at Yeo Valley’s Holt Farm near Blagdon, south of Bristol.
