Summary

This multi-country European field study examined whether maintaining continuous crop cover or increasing rotational diversity more strongly drives soil multifunctionality and cereal yields. The findings suggest, as indicated by the title, that continuous crop cover is a more important determinant of soil health and productivity than the number of crops rotated through a system. The work contributes to ongoing debate about which management practice most effectively supports both soil ecosystem services and grain production in temperate arable systems.

UK applicability

Findings are directly relevant to UK arable practice, given climatic and agronomic similarity to participating European regions. The emphasis on crop cover year-round may have particular policy relevance for UK environmental stewardship schemes and future agricultural support post-CAP transition.

Key measures

Soil multifunctionality (composite measure of multiple soil functions), cereal yields, rotational diversity metrics, crop cover duration and frequency

Outcomes reported

The study compared the relative importance of continuous crop cover versus rotational diversity in determining soil multifunctionality and cereal yield across European cropping systems. Soil functioning and grain production were measured as primary outcomes.
