Summary

This long-term field experiment (1980–2019) in the southeastern US quantifies how contrasting tillage regimes influence soil organic carbon accumulation and physical aggregation. The study contributes empirical evidence on soil structural resilience under different mechanical disturbance histories, informing best management practices for carbon sequestration and soil health in arable systems.

UK applicability

Findings on tillage effects on soil carbon and aggregation are broadly relevant to UK arable practice, though southeastern US soils, climate and cropping systems differ from British conditions; direct transfer of management recommendations would require consideration of local soil type, rainfall and crop selection.

Key measures

Soil organic carbon content; soil aggregate stability; aggregate size distribution; as suggested by typical long-term tillage experiments

Outcomes reported

The study examined soil organic carbon concentrations and soil aggregate stability across multiple tillage treatments maintained over 39 years in the southeastern United States. Measurements likely included carbon storage, aggregate size distribution, and water stability as indicators of soil structure and quality.
