Drivers of organic carbon dynamics in surface and subsurface agricultural soils of New South Wales, Australia

Context Understanding of organic carbon (OC) stock in surface (0–30 cm) and subsurface (30–60 cm) soils and its determinants are crucial for managing OC in agricultural lands. Aim Our aim was to examine how land use, soil type, and environmental drivers influence OC stocks in the 0–60 cm soil layers of agricultural regions in New South Wales (NSW), Australia. Method Soil OC (SOC) and nitrogen (N) stocks were measured across diverse soil types from 49 farms representing pastures and cropping in N
