Summary
This paper examines on-farm soil health trajectories in Southern US row crop systems, evaluating how current management practices compare to the estimated soil health potential for given soil types and climatic conditions. Drawing on established soil health assessment frameworks — likely including the Comprehensive Assessment of Soil Health (CASH) or similar — the authors assess the gap between current and achievable soil health. The study contributes empirical on-farm data to understanding the practical ceiling for soil health improvement under row crop agriculture in a climatically challenging region.
UK applicability
The study is US-specific and focuses on Southern row crop systems with distinct soil types, climate, and management contexts. However, the methodological approach to benchmarking on-farm soil health against biophysical potential has direct relevance to UK efforts to develop soil health monitoring frameworks, including those underpinning agri-environment schemes and the Environmental Land Management programme.
Key measures
Soil health indicators (likely including organic matter, aggregate stability, biological activity, and nutrient cycling metrics); soil health potential scores; on-farm management practice data
Outcomes reported
The study likely assessed the degree to which farms in the Southern United States are progressing towards their soil health potential, using soil health indicators to benchmark current status against estimated achievable levels under improved management practices.
