Enhanced anthropogenic nitrogen (N) inputs to ecosystems may have substantial impacts on microbially mediated soil organic carbon (SOC) cycling. One way link species-rich microbial communities with SOC cycling processes is via extracellular enzyme activities (EEAs). However, the effects of N addition EEAs and associated driving factors remain poorly understood. By conducting a meta-analysis, we find that increases hydrolytic C-degrading target simple polysaccharides decomposition by 12.8%, but decreases oxidative degrade complex phenolic macromolecules 11.9%. The net effect storage determined shifts between these two types EEAs, varied across different ecosystem types. These insights highlight crucial understudied roles dynamics ongoing enhanced loading. Understanding mechanisms behind could help optimize sequestration inform climate mitigation strategies ecosystems.

Soil organic carbon (SOC) is a crucial indicator of soil quality and fertility. However, excessive nitrogen (N) application, while increasing Moso bamboo yield, may reduce SOC content, potentially leading to issues. The impact N on its active fraction in forests remains underexplored. Investigating these effects will elucidate the causes decline inform effective management strategies. Four application gradients were set: no (0 kg·hm−2·yr−1, N0), low (242 N1), medium (484 N2), high (726 N3), with fertilizer as control (CK). We analyzed changes SOC, components, Carbon Pool Management Index (CPMI) under different treatments. results showed that components 0~10 cm layer more susceptible N0 treatment significantly increased microbial biomass (MBC) content but had significant effect particulate (POC), dissolved (DOC), readily oxidizable (ROC) contents. N1, N2, N3 treatments reduced by 29.36%, 21.85%, 8.67%, respectively. Except for POC, N1,N2 MBC, DOC, ROC contents 46.29% 71.69%, 13.98% 40.4%, 18.64% 48.55%, MBC/SOC ratio can reflect turnover rate lowered ratio, N1 < N2 N3, indicating slowest treatment. Changes illustrate sequestration capacity. CPMI, an improvement comprehensive evaluation index capacity (−0.69) (−0.13) CK (−0.05) (0.24) (0.63), highest gradual decrease concentration. In summary, although it CPMI decreased rate, benefiting Therefore, reasonable key improving storage forests.

The application of nitrogen fertilizer is crucial in the cultivation bamboo forests, and comprehending alterations soil organic carbon (SOC) due to essential for monitoring quality. Predicting dynamics stock involves analyzing two components: particulate (POC) mineral-associated (MAOC). This study aimed investigate impact high inputs on SOC Moso forests located southwestern China. research focused changes chemical properties, content, its components (POC MAOC), as well microbial biomass surface layer (0–10 cm) under different applications (0, 242, 484, 726 kg N ha−1 yr−1). results indicate that significantly reduced while concurrently causing a significant increase POC content decrease MAOC within forest (p < 0.05). HM treatment notably increased NO3−-N 2.15 mg/kg decreased NH4+-N 11.29 mg/kg, although it did not influence (MBC) (MBN). LN MN treatments MBC MBN contents (71.6% 70.8%, 62.5% 56.8%).
