Soil microorganisms transform plant-derived C (carbon) into particulate organic (POC) and mineral-associated (MAOC) pools. While microbial carbon use efficiency (CUE) is widely recognized in current biogeochemical models as a key predictor of soil (SOC) storage, large-scale empirical evidence limited. In this study, we proposed experimentally tested two predictors POC MAOC pool formation: necromass (using amino sugars proxy) CUE (by 18O-H2O approach). sampling (0-10 10-20 cm depth) was conducted along climatic transect 900 km on the Loess Plateau, including cropland, grassland, shrubland, forest ecosystems, to ensure homogeneous parent material. We found highest accumulation occurred zones MAT between 5°C 10°C or MAP 300 500 mm. Microbial more positively related than (p < 0.05), suggesting that residues may improve strongly compared pool. Random linear regression analyses showed increased with fungal C, whereas bacterial drove MAOC. coupled 0.05) but decoupled SOC > 0.05).

Our findings highlight insufficiency relying solely predict bulk storage. Instead, propose should be used together explain dynamics, each influencing distinct

Farmland ecosystems are the most active carbon pool and contribute significantly to global cycle. Since these influenced by both natural human factors it is important study their roles as sources sinks in order reach "peak emissions" "carbon neutrality" goals. This review provides a systematic summary of research this area explores deficiencies current approaches addressing common flux accounting methods mainstream cycle measurement models. Natural that affect functions farmland discussed prospects for existing problems suggestions future directions presented. The affecting ecosystem have great heterogeneity complexity due differences management practices conditions with former being more important. However, assessment models methods, there still uncertainty ecosystems. Therefore, emphasis needed on optimization improvement future. comprehensive reference further ecosystems, rational adjustment measures, strategies reduction agricultural non-point source pollution.
