Mapping surface soil organic carbon in the coal–grain composite area: threshold and interaction effects of coal mining activities

Abstract Background In China, the coal–grain composite area accounts for more than 40% of the total cultivated land area, and its soil organic carbon (SOC) content profoundly impacts soil health and food security. However, underground coal mining causes surface subsidence, farmland degradation, and...
