Sustainable soil management in the <scp>UK</scp> : a survey of current practices and how they relate to the principles of regenerative agriculture

Abstract

Sustainable soil management is essential to prevent agricultural soil degradation and maintain food production and core soil-based ecosystem services. Regenerative agriculture, one approach to sustainable soil management, is rapidly gaining traction in UK farming and policy. However, it is unclear what farmers themselves consider to be sustainable soil management practices, and how these relate to the principles of regenerative agriculture. Further, there is little insight into how sustainable soil management is currently promoted in agricultural knowledge and innovation services (AKIS). To address these knowledge gaps, we undertook the first national-scale survey of sustainable soil management practices in the UK, and complimented it with targeted interviews. We found high levels of awareness (>60%) and uptake (>30%) of most sustainable soil management practices among mixed and arable farmers. Importantly, 92% of respondents considered themselves to be practising sustainable soil management. However, our analysis shows that farmers combine practices in different ways. Not all these combinations correspond to the full set of regenerative agriculture principles of reduced soil disturbance, soil cover and crop diversity. To better understand the relationship between existing sustainable soil management practices in the UK and regenerative agriculture principles, we derive a ‘regenerative agriculture score’ by allocating individual practices among the principles of regenerative agriculture. Farmers who self-report that they are managing soil sustainably tend to score more highly across all five principles. We further find that sustainable soil management messaging is fragmented, and that few AKIS networks have sustainable soil management as their primary concern. Overall, our study finds that there are multiple understandings of sustainable soil management amongst UK farmers and land managers, and that they do not correspond to regenerative agriculture principles in a straight-forward way. This diversity and variety in sustainable soil management needs to be taken into account in future policy and research.
