Integrated Soil–Crop System Management Promotes Microbial Necromass and Soil Organic Carbon Sequestration in Black Soil Through Microbial Transformation and Aggregate Protection
Long-term intensive cultivation has degraded soil structure and reduced soil organic carbon (SOC) retention in the black soils of Northeast China. However, the processes underlying SOC accumulation under integrated soil–crop system management (ISSM) remain poorly understood. An 11-year field experiment compared farmers...
