Implication

Conceptual framework reveals enhanced organic matter stabilization in mineral soils, suggesting easily degradable plant inputs drive long-term carbon storage.

Key Points

To integrate plant litter decomposition with soil organic matter stabilization mechanisms and examine whether labile plant inputs preferentially form stable soil organic matter.
Synthesized existing empirical and theoretical literature on microbial substrate use efficiency, carbon and nitrogen allocation, and mineral soil matrix interactions.
Constructed the Microbial Efficiency-Matrix Stabilization (MEMS) conceptual framework connecting litter decay dynamics to long-term soil organic matter preservation.
Demonstrated that labile plant components serve as the dominant precursor for microbial biomass products because microbes utilize labile substrates with higher efficiency than recalcitrant compounds.
Identified that microbially derived compounds are stabilized within the soil through physical aggregation and chemical bonding to the mineral soil matrix, forming long-lived soil organic matter.
