Abstract

The study investigated how microbial metabolic processes influence soil organic carbon (SOC) accumulation in response to varying nitrogen (N) supply from crop residues. Using metagenomic analysis, NMR, and <sup>15</sup>N labeling, they found that residue amendment increased genes involved in carbon degradation and N mineralization. These genes correlated with C and N accumulation in SOC pools, suggesting microbial transformation of residues into persistent organic compounds, enhancing C and N sequestration.
