The formation and sequestration of soil organic carbon (SOC) in croplands are significantly regulated by microbial necromass, a process strongly influenced by agricultural management. However, how management affects microbial necromass carbon (MNC) and its contributions to SOC stocks from an agroecological perspective remains insufficiently understood. To address this issue, the authors collected 834 paired aggregated experimental data from 77 studies worldwide, incorporated the influence of climate factors and soil physical and chemical properties, and constructed a necromass carbon database to reveal the impact of cropland management practices on microbial necromass and SOC.
