  1. SOC, soil organic carbon; MBC, microbial biomass carbon; DOC, dissolved organic carbon; POC, particulate organic carbon; MAOC, mineral-associated organic carbon. The data in the table represent mean values ± standard error; with n = 4. Different lowercase letters indicate significant differences between treatments (P < 0.05).
