Fauna is highly abundant and diverse in soils worldwide, but surprisingly little known about how it affects soil organic matter stabilization. Here, we review the ecological strategies of a multitude faunal taxa can affect formation persistence labile (particulate matter, POM) stabilized (mineral-associated MAOM). We propose three major mechanisms - transformation, translocation, grazing on microorganisms by which fauna alters factors deemed essential POM MAOM, including quantity decomposability mineralogy, abundance, location, composition microbial community. Determining relevance these to MAOM cross-disciplinary studies that cover individual more complex communities, employ physical fractionation, isotopic, microbiological approaches advance concepts, models, policies focused effectively manage as carbon sinks, nutrient stores, providers food.

Unlocking Mechanisms for Soil Organic Matter Accumulation: Carbon Use Efficiency and Microbial Necromass as the Keys

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).
