To Till or Not to Till - In Conversation with Julia Cooper

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...
