This is the first episode of a new series exploring agroforestry, in which we use the elements as a framework to deepen understanding and challenge assumptions around trees on farms. The overarching aim is to explore how trees on farms contribute to more than just individual functions, holding the ability to transform whole landscapes and ecosystems. 'Water' includes exploring how trees impact flood risk, rainfall, and soil moisture. Guest podcaster Wallace Currie is joined by Ben Raskin, Head of Agroforestry at the Soil Association and co-organiser of the Agroforestry Show, who brings a wealth of knowledge about using trees effectively to manage extremes of water in a changing climate. Colin Tosh, Senior Agroforestry Researcher at the Organic Research Centre talks about his work modelling agroforestry systems to understand how trees impact water on farms through their influence on rainfall interception, soil characteristics, and microclimates. Vicki Hird, a lady of many hats, including being Strategic Lead on Agriculture at The Wildlife Trusts, touches on the challenges of water pollution caused by agriculture and sewage companies and how agroforestry can help tackle these issues, and talks about her work with lowland peat soils.

In the last episode of the series, plant ecologist Jonathan Storkey treats us to fascinating insights on biodiversity in production systems and soil microbial communities, emphasising how context is crucial when choosing your tillage approach. He shares his journey from birdwatching ecologist to leading weed scientist at Rothamsted Reseach, where he has been studying tillage and biodiversity interactions for over two decades.

He dives into the concept of "functional biodiversity"- pollinators, predators, and microbes that support food production, and how tillage impacts those delicate systems. We explore the Rothamsted long-term systems trials, where contrasting tillage approaches across different soil types are revealing nuanced shifts in yield, weed pressure, soil carbon, and microbial succession. Jonathan explains how early-stage bacteria-dominated soils differ from more stable fungal systems, and how physical disturbance resets succession.

He also explores glyphosate reliance (including glyphosate-resistant weeds), weed control trade-offs, IPM potential, and the resilience of different systems to extreme weather events.

This third episode of the new Agricology podcast season features Kate Still from the Soil Association's Farming and Land Use team. Kate comes to the conversation with a whole farm approach in mind and the need to balance what farms can support to create healthy animals, healthy farmers and a healthy farm bank balance with as few inputs as possible. Her quiet wisdom comes across as she considers strategies and approaches to optimising rather than maximising livestock production. We discuss the highlights from some of the Innovative Farmers field labs Kate's been involved with, which have looked into strategies including the use of herbal leys, winter forage options and transitioning to new grazing systems. We speak about the challenges of getting new grazing strategies 'right,' having the infrastructure to make rotational grazing happen, and training staff to be able to do this.

In this episode we are joined by Dr Lindsay Whistance, Senior Livestock Researcher at the Organic Research Centre. Lindsay, who started her working life as a dairy herds-woman, comes to the conversation through the lens of animal welfare. The episode is an enlightening exploration of thoughts and ideas relating to optimal carrying capacity. It covers topics including the important partnership between humans and livestock which can be lost when animals are reduced to being just a tool, and the need for wider acknowledgement of animals' fundamental place in the ecology of a landscape, being critically important to ecological health. Lindsay touches on how we can provide for animal's needs, farming in a way that allows animals to adopt natural behaviours, and approaches that can help balance the relationship between human, animal and environment. She also considers peoples different conceptions of "good animal welfare" and the challenges associated with focusing on health in the round.

In the first of a new series exploring optimal carrying capacity, we speak to biodynamic farmer Richard Gantlett, from Yatesbury House Farm in Wiltshire. He talks about farm operations and highlights the approaches used; from dynamic rotational grazing to the role of herbal leys, and what he refers to as being a "forest farm approach." He explains how spending time with Alex Podolinsky has inspired the emphasis he now puts on the use of observation as a farmer. We look into the environmental impacts of livestock and Richard explains how research on his farm shows he has a negative carbon balance. He also touches on some of the tricky elements of the debate surrounding livestock emissions, and perceptions around this subject.

In this episode we explore the science and practice of biofumigation - the use of a temporary brassica (mustard) cover crop to help manage soil pathogens and weeds. Katie Bliss introduces footage from a webinar which features researcher Dr Matthew Back (Harper Adams University) and Alec Roberts (Tozer Seeds) in a lively discussion with a group of growers innovating with enhancing diversity in protected cropping as part of the DiverIMPACTS project.

Mike Mallett is farm manager of Maple Farm Kelsale, a 138-hectare organic farm in Suffolk which is mostly arable with some permanent pasture, woodland, horticulture & laying hens. He talks about regenerative agriculture, beneficial weeds, intercropping, the extensive agroforestry on the farm & providing for the hens' health & welfare, with some fascinating insights; from breed selection to innovations in feed supply & his involvement in OK-Net Ecofeed. View the full farmer profile on the Agricology website.

In this episode we hear from organic mixed min till farmer John Pawsey & arable conservation ag no-till farmer Clive Bailye in featured footage from an online event 'Know your soils and know your sales' that took place in July 2020 as part of OF&G's NOCC, with support from the AHDB. Renowned broadcaster Charlotte Smith leads the conversation which focuses on their approaches & practices they deploy that equip their farming businesses with resilience in light of the many environmental & economic challenges.

Richard farms beef cattle & cereals biodynamically at Yatesbury House Farm in Wiltshire UK. In this episode we talk to him about his involvement in the Farm System Health project; which brought together international farmers who have established personal philosophies & strategies of best practice that make them successful in running healthy farms & producing healthy food. Richard reflects on exploring health principles with the farmers & how these principles are embedded in his farming practices & approach.

Iain Tolhurst runs one of the longest running stock-free organic vegetable farms in England. In this episode we talk to him about his involvement in the Farm System Health project - which brought together international farmers who have established personal philosophies & strategies of best practice that make them successful in running healthy farms & producing healthy food. We ask him what farm system health means to him & how he relates his practices to the 10 principles of health defined in the project. 

In this episode with farmer John Pawsey, we talk about the role of tillage in organic systems, balancing weed and pest pressures, how regenerative overlaps with organic, and how diversity drives success. John shares his journey from conventional spraying to organic, mixed farming (over 25 years ago). He explains why he ploughs selectively (once or twice in a six-year rotation) and how organic farming pushes innovation through the limits of its standards. His approach is rooted in observation, adaptability, and profitability.

We explore how he adjusts tillage depth based on weed type and the importance of bringing complexity into your rotation and not letting one problem dominate – in relation to weeds, pests and diseases.

John reflects on reducing his sheep flock, soil health gains (now having up to 6% organic matter), and embracing Groundswell and regenerative ideas with an organic mindset. He describes a farming system built on context: some years min-till, others plough, all underpinned by leys, cover crops, and diversity in crops and drilling dates. His honesty about the learning curve, headspace shifts, and financial sustainability gives real-world clarity to the tillage debate.

Wendy Seel runs "organic, grown with nature, small scale & local" Vital Veg at North Tillydaff farm near Aberdeen. She describes the design of their growing system, ways in which they build soil fertility, attract pollinators & pest predators, increase biodiversity, & get as much diversity & variation in time, space & variety as they can. She particularly focuses on the way in which trees have been integrated & the many beneficial functions they serve. View the full farmer profile on the Agricology website.

Jonathan Smith, organic grower on St Martins, Isles of Scilly, talks about why he farms as he does and describes how he uses seaweed, compost and green manures to build soil organic matter and fertility. He touches on challenges he faces, treating the farm like an ecosystem; focusing on biodiversity, and explains how he has used the Farm Carbon Calculator to gain more detailed understanding of his farm and inform his practices. View the full farmer profile on the Agricology website.

In this latest podcast we are 'In the field' with Julian Gold, farm manager of 800 ha of combinable crops at Hendred Estate in Oxfordshire. He introduces the farm & talks about experiences & aspirations of transitioning to farming in a way that is less harmful to the environment & biodiversity. He describes his soil health & carbon capture strategy, biological methods of pest control trials he is running, & his drive to reduce nitrogen use. You can view the full farmer profile on the Agricology website.

The third episode of the series welcomes the Organic Research Centre's Julia Cooper who shares her expertise as a soil scientist. We look at soil health from a scientific perspective, focusing on nutrient cycling, carbon sequestration, and the nuanced role of tillage across different soil types and farming systems. Julia explains how soil health is context-specific, emphasising the importance of balancing biology, water management, and soil structure, rather than seeking one-size-fits-all solutions.

We dive into how tillage affects water retention, soil productivity and microbial life, and discuss trade-offs between conventional and reduced tillage, looking at how practices such as direct drilling and cover cropping interact with climate and soil type, rather than existing as binary choices.

We also touch on glyphosate versus plough-use in regenerative and organic systems, with Julia advocating for pragmatic, context-led decisions. Her insights offer a roadmap for farmers to make informed, resilient choices suited to their own land and goals...

This second episode with Mark Measures explores the role of tillage in organic systems, the misunderstood relationship between tillage and soil carbon, the balance between weed control and nutrient cycling, and how tillage fits into wider farming systems. Mark reflects on 40 years in organic advice, with deep roots in research, education, and farmer engagement.

He argues that tillage, especially shallow and strategic, plays a crucial role in organic farming; not only for weed control and seedbed preperation, but also for stimulating nutrient release and building long-term stable carbon. He explores common misconceptions such as the oversimplified view that all tillage depletes soil organic matter, and explains that tillage can mineralise nutrients and stabilise humus, which is essential for carbon sequestration and water retention. He also challenges the belief that zero-till is the pinnacle of organic, pointing to climate and system-specific limitations.

Mark advocates for strong rotations, fertility-building leys, and shallow, context-sensitive ploughing. He emphasises that tillage must be considered as part of a broader ecological, economic, and agronomic strategy - balanced, site-specific, and always evolving.

The first episode of our latest series introduces both Wallace Currie, guest podcaster from the Isle of Arran (search R2Kast), who will be chatting to guests throughout the series, and Cambridgeshire farmer Tom Martin. They discuss transitioning to no-till, the emotional and practical side of regenerative farming, redefining success through mistakes, and the value of community and biodiversity in agroecological systems.

Tom shares his life journey from Universal Pictures to working back on the family farm, explaining how those soft skills transferred to his role as a regenerative farming advocate. The farm has gradually moved from full inversion tillage to almost no-till – driven by soil health, improving drainage and weed pressure, and a desire to farm more efficiently.

The conversation explores how Tom integrates companion cropping, livestock grazing, and molasses and biochar to support the soil microbiome. Mimicking nature and context-driven change are key to his success and philosophy.

The penultimate episode of this season sees us in conversation with Dan Stevenson, the Head of Integrated Farm Management (IFM) at LEAF. Dan comes to this topic with nearly 20 years' experience as a farm animal vet. He discusses his veterinary background and the arc his career has followed; moving on to working with LEAF, and along the way starting to think more holistically about livestock production, with a focus on a whole systems approach. We explore the key role nutrition plays within livestock systems and finding the balance between nutrition and animal health. Further to this, Dan touches on mental health, we explore the challenges of adopting extensive systems, and the importance of setting objectives on farms to help support optimal carrying capacity.

We are joined by the Sustainable Food Trust's Senior Researcher Robert Barbour for our sixth episode of this season. Tune in to discussions surrounding methane, carbon footprints, and the complexities and challenges of measuring environmental impacts associated with livestock. Robert draws on his experiences as a researcher and his family farm (an upland beef and sheep farm that also produces timber in Highland Perthshire, just north of Pitlochry), to dive into the positive role livestock can play from a food systems and environmental perspective. He considers grazing strategies, livestock breeds, and the role herbal leys can play, whilst emphasising the productivity levels that can be achieved in pasture-based systems. He points out his family farm is running a system that has very low levels of inputs so what determines their carrying capacity is largely what the land can naturally support, and one limiting factor for them is a lack of early season grass growth.

The fifth episode of the season finds us in conversation with Simon Fairlie, recorded earlier this summer when he was still running his dairy operation at Monkton Wyld Court in Dorset. Simon, who was once described by the Guardian as "the most influential and unusual eco-activist you might not have heard of", brings us a wide ranging conversation that looks at the micro and the macro of carrying capacity. You'll find us discussing how he managed his herd of two as he produced a range of dairy products for the 'intentional community' at Monkton, and how he dealt with grazing and hay production whilst improving grasslands and considering the ecological benefits his approach brought to the 8 acres under his management. This couples with a wider food systems discussion around the role of livestock, rewilding, methane emissions, and the issues associated with an unbalanced production system where he argues the case for a return to mixed farming being required. 

In this fourth episode we are joined by renowned conservation grazier Bill Grayson who brings us his perspective on the concept of optimal carrying capacity and the way that it is deployed within the system he and his wife Cath run as part of the Morecambe Bay Conservation Grazing Company. He discusses how they go about planning putting animals on to a piece of land, the various practical considerations, and the role livestock play and the benefits they can bring to the land, along with the main challenges in relation to the conservation grazing picture against a backdrop of a pervading opinion of ruminants causing climate change. We touch on the impacts of stocking rate, forage management, breed selection, extended calving period, the set stocking versus mob grazing approach, and the difference between 'maximum sustainable output' (essentially an economic interpretation) and optimal carrying capacity, and how it fits with agroecological principles.

From the early days of crofting and subsistence farming to the present day, animal protein has provided an essential and highly valuable source of nutrients for Arran's population. While sheep and beef production have always been central to Arran's farming economy, venison is now also being embraced as a sustainable protein source that can help to combat the growing threat that the wild deer population poses to island ecosystems.

In this first episode of our new series Agroecology Around Arran, we explore how the production of meat on Arran embraces the ethos of agroecology, how farmers are working together to reduce carbon emissions from livestock farming, and what we can learn from their example.
