Abstract

Conversion of plant residues to biochar is an attractive strategy for mitigation of atmospheric carbon dioxide (CO₂) emission and enhancement of carbon (C) storage in soil. However the effect of biochar application on the decomposition of soil organic C (SOC) as well as its mechanisms is not well understood in the sandy loam soil of North China Plain. We investigated how biochar affected the decomposition of native SOC using stable δ<
