A two‐tier, reference‐informed framework for soil health assessment: Minimum indicator sets and ecologically dynamic thresholds

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Soil health underpins crop productivity and sustainability, but current soil health assessment frameworks struggle to balance global standardization with regional dynamic ecological realism. Indicators vary widely across soils and climates, often leading to one‐size‐fits‐all thresholds that penalize producers in inherently low‐capacity soils ...
