Contrasting mechanisms of soil carbon sequestration in upland soils: Fungal-driven physical protection with straw versus bacterial-driven mineral stabilization with biochar.
Understanding the distinct mechanisms by which straw and biochar regulate soil organic carbon (SOC) sequestration is essential for optimizing agricultural practices. To investigate the physical-microbial coupling mechanisms of SOC sequestration, we amended three upland soils collected from Yuzhong (YZ), Yangling (YL),...
