Agricology in the Field - Wendy Seel

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.  Show notes: Explore the two papers by Hannah Van Zanten, the paper Robert wrote with Richard Young and Michael Wilkinson that looks at the production of meat and milk from grass, the Agricology profile of his family farm, and learn more about GWP and GWP* here: https://tinyurl.com/5dr8kv75 

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.

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.   Show notes: Read about the field labs Kate mentions, the University of Reading diverse forage programme, and the work of New Zealand Advisor John King here: https://tinyurl.com/5dr8kv75   

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.

This episode features our visit to Three Hagges where we were shown around by Woodmeadow officer Dan Carne & one of the founders Ros Forbes Adam. They talk about what a woodmeadow is, potential relevance to farmers, layout of the site, how it was created & is now managed, tips for farmers interested in putting some land over to a combination of woodland & meadow, & thoughts about wider scale adoption of woodmeadows & agroforestry. It is produced as part of 'A National Network of Agroforestry Farms' project. View accompanying notes & site photographs here.

Organic livestock farmers Bill & Cath Grayson run the Morecambe Bay Conservation Grazing Company. They practice conservation grazing on semi-natural habitats of woodland & limestone grassland scrub which can be described in agroforestry terms as wood pasture. Our editor talks to them about what they do, how they came to do it, benefits & challenges they’ve encountered & thoughts on wider scale adoption of agroforestry. The episode is produced as part of 'A National Network of Agroforestry Farms' project.  View the farmer profile for Bill & Cath Grayson here.

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.
