Short summary
We used a global dataset to examine patterns and drivers of fungal necromass C (FNC), bacterial necromass C (BNC), and their ratio across agricultural and natural ecosystems. FNC contributed about twice as much as BNC to soil organic carbon (SOC) in both systems, with higher contributions overall in agricultural soils. Soil C/N and clay content mainly drove FNC and BNC contributions, while elevation primarily influenced the FNC/BNC ratio.
