Effects of different biochar application rates on CH4 emissions and Microbial Carbon Pump (MCP) mediated carbon sequestration in paddy fields: a quantitative modeling approach.
Biochar amendment is a proven strategy for mitigating methane (CH4) emissions and enhancing soil carbon sequestration in rice paddies. However, the depth-dependent dynamics of microbial carbon pump (MCP)-driven recalcitrant organic carbon (ROC) formation and the underlying microbial mechanisms remain poorly characteriz...
