Summary
This multi-country European field study evaluated whether maintaining continuous crop cover or increasing rotational diversity more strongly supports soil multifunctionality and cereal productivity. The research, published in Nature Food in 2021, suggests that crop cover may be a more influential management lever than crop rotation diversity for maintaining multiple soil functions and sustaining yields in temperate cropping systems, as indicated by the title.
UK applicability
The study's focus on European cereal systems and soil-crop interactions is directly relevant to UK arable farming, where both winter and spring cereals predominate. Findings on crop cover practices (such as cover cropping between cash crops) have potential application to UK agri-environment schemes and sustainable intensification policy.
Key measures
Soil multifunctionality index, cereal grain yields, soil microbial community composition, crop cover extent, rotational diversity metrics
Outcomes reported
The study compared the relative importance of crop cover versus rotational diversity for soil multifunctionality (measured across multiple soil functions) and cereal grain yields across European cropping systems. It assessed how these management practices influenced soil microbial communities and overall soil health.
