Summary
This synthesis by Cotrufo and Lavallee reviews the mechanisms governing soil organic matter formation, stabilisation, and persistence to inform evidence-based conservation and regeneration strategies. The paper integrates contemporary understanding of SOM dynamics—including the role of microbial processes, mineral associations, and environmental drivers—to support practical improvements in soil health across farming systems. As a review, it provides a conceptual and mechanistic foundation for interpreting SOM responses to management interventions.
Regional applicability
The mechanistic principles presented are relevant to UK soil conditions and temperate agricultural systems, particularly regarding SOM management under varied climates and soil types. Findings could inform UK soil health policy, environmental stewardship schemes, and regenerative farming guidance.
Key measures
Soil organic matter concentration, persistence, microbial decomposition pathways, carbon stabilisation mechanisms, and agronomic/ecological functions
Outcomes reported
The study synthesised current understanding of soil organic matter (SOM) formation mechanisms, persistence pathways, and functional roles in soil ecosystems. It evaluated evidence-based approaches to SOM conservation and regeneration across diverse agricultural contexts.
