“A yield-correlated minimum soil dataset — total organic carbon, microbial biomass carbon, active carbon, total nitrogen and aggregate stability — tracked full-dataset soil quality scores closely (R² 0.53–0.93) and beat the usual PCA-selected indicator set. Pairing linear scoring that uses threshold limits with simple additive indexing kept soil quality index values within ±1% of the full dataset, giving farmers and advisers a cheaper, transferable way to rate soil quality across corn–soybean sites in Alabama, Indiana and Ohio.”
