Notes: CK: no fertilization; NPK: chemical fertilizer; M: organic fertilizer; MNPK: constant organic-inorganic fertilizer. C₀, amount of potential mineralizable SOC; k, constant of mineralization rate of SOC; T_1/2, half turnover period; C₀/SOC, ratio of potential mineralizable organic carbon to total organic carbon in soil. Different small letters indicate significant differences (P < 0.05) within the same column.

**, statistically significant (P < 0.01)
