Table 4 Decomposition constant (k0, × 10− 3, day− 1) obtained through fitting the model (\( {C}_{cum}(t)={C}_0\times \left(1-{e}^{-{k}_0t}\right) \)) to cumulative mineralized carbon (C cum ) at temperature and moisture incubation conditions

From: Recalcitrant carbon controls the magnitude of soil organic matter mineralization in temperate forests of northern China
