Short summary
A field experiment was conducted to compare and analyze the effects of combined application of biochar and nitrogen fertilizer on soil aggregate stability mechanism, the dynamic characteristics of aggregate organic carbon, and the microbial community structure in northeast black soil. We provide a scientific basis for formulating effective strategies to slow down soil quality degradation and ensure the sustainable development of the agroecosystem.
