High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers

Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. However, studies limited to the surface layer cannot fully reveal the complete response of SOC to nitrogen input because approximately half of the SOC is stored in deeper soil layers. Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems.
