Summary

This review examines the potential of herb- and legume-rich multispecies leys within arable crop rotations to address soil degradation resulting from agricultural intensification and continuous cropping. The authors evaluate existing research on multispecies leys, emphasising that botanical composition is crucial for delivering benefits, and identify substantial evidence gaps—particularly regarding ruminant health, livestock emissions, and long-term soil dynamics—that hinder adoption in arable-dominated regions lacking livestock infrastructure.

UK applicability

Highly applicable to UK agriculture, as arable-ley rotations are promoted through agri-environment schemes and align with soil health and climate goals. However, adoption barriers in arable-specialist regions require integrated policy support for livestock infrastructure and market mechanisms to realise potential benefits.

Key measures

Soil degradation and erosion; soil fertility and structure; livestock health outcomes; greenhouse gas emissions; ecosystem services; botanical composition effects

Outcomes reported

The review synthesised evidence on how multispecies leys (temporary pastures containing grasses, legumes, and herbs) affect soil quality, livestock productivity, and greenhouse gas emissions when integrated into arable rotations. It identified botanical composition as critical to determining agronomic and environmental benefits.
