Abstract:Efforts to address economic and environmental concerns surrounding nitrogen (N) have motivated attempts to improve estimates of plant‐available N in soil. Several soil health indicators, including CO2 burst, permanganate oxidizable carbon (C) (POXC), and autoclaved‐citrate extractable (ACE) soil protein, assess labile C and N, and therefore may help to estimate soil N mineralization in long‐term cover cropping systems (>3 years). This study evaluated the relationship of CO2 burst, POXC, ACE‐soil protein, an… Show more
