Soil microorganisms play key role in the carbon release process through various pathways and functions. Currently, the dynamic non-equilibrium state of the soil carbon cycle and the microbial carbon pump storage mechanism are widely recognized in the soil microbial carbon cycle ( Luo and Weng, 2011; Zhu et al., 2020 ).
We suggest that the magnitude of soil C storage is largely controlled by the balance between microbial catabolic activity, which releases C as CO 2, and anabolic activity, which contributes ...
The transformation of "energy to (soil organic) matter" has long been the focus of scientific attention (Swift et al., 1979), but no definitive conceptual framework exists.
