The interaction between organic matter (OM) and soil minerals influences the storage and turnover of soil organic carbon (SOC). However, the mechanism of how mineral-bound organic carbon (MAOC) protects SOC under the interaction between OM and minerals in saline-alkali soil is still unclear. a 7-years field experiment with two factors was designed, which included two nitrogen(N) levels (N1 and N2) and three straw returning treatments (SR0, SR1 and SR2).
