Microbial residues as the key component of stable soil organic carbon (SOC) play a critical role in stabilizing SOC, and their accumulation is influenced by plant litter. However, how microbial different aggregate fractions forest soils responds to changes inputs leaf root litter remains poorly understood. Here, we test hypothesis that exclusion has greater effects on than leaf-litter among based litter-input manipulation experiment subtropical coniferous forest. The concentrations bacterial, fungal, total were higher large macroaggregates (> 2000 μm) but lower small (250–2000 μm). Root decreased microaggregates (< 250 μm), fungal microaggregates. Fungal had proportions SOC (20.7–34.9%) bacterial (10.8–18.6%) fractions, other fractions. reduced (14.5%, 15.7%, 15.3%, respectively), compared reduction observed (10.8%, 7.1%, 8.4%, respectively). And Soil residue-carbon coefficient was macroaggregates. increased microaggregates, it also Proportions more strongly related live biomass nutrients those residues. Our results suggest exerts stronger these vary sizes.

Effective soil organic carbon (SOC) management can mitigate the impact of climate warming. However, response different SOC fractions to warming in abandoned croplands remains unclear. Here, categorizing into particulate and mineral-associated (POC MAOC) with physical fractionation, we investigate responses POC MAOC content temperature sensitivity (Q10) through a 3-year situ experiment (+1.6 °C) across 12 sites China (latitude: 22.33–46.58°N). Our results indicate that unchanged while significantly increases under changes are mainly influenced by root biomass microbial necromass changes, respectively. The Q10 is lower than regardless or control treatment, suggesting represents most persistent least vulnerable fraction within SOC. Collectively, sequestration stable be enhanced short-term Natural recovery generally benefits accrual croplands, but on this ecosystem authors showed enhances these lands.
