Summary

This field-based study by Loaiza Puerta and colleagues investigated how organic crop management combined with conservation tillage and grass-clover ley rotations affect soil structure development. The research suggests that these management practices—typical of regenerative and organic farming systems—can enhance soil physical properties and structural stability, supporting long-term soil health and functioning.

UK applicability

The findings are directly applicable to UK organic and conservation agriculture systems, particularly in temperate climates. The grass-clover ley approach aligns with UK agro-ecological practice and ELMS (Environmental Land Management Scheme) objectives around soil health and carbon storage.

Key measures

Soil structure stability, aggregate size distribution, porosity, bulk density, and related physical soil properties

Outcomes reported

The study examined changes in soil structure and related physical properties under different management practices including organic crop production, conservation tillage, and grass-clover ley incorporation. Soil structural stability and aggregate formation were assessed as primary indicators of soil quality improvement.
