Abstract Converting crop residues into biochar and subsequently incorporating it soils is a promising strategy to improve carbon sequestration in agroecosystems. However, differences the potential mechanisms for soil organic (SOC) accumulation between its feedstock materials remain unclear. This study performed nine-year field experiment involving four treatments Mollisol: mineral fertilizers alone combined with maize straw or biochar, control without amendments. The main objectives of this were assess how incorporation influence SOC content, chemical composition, microbial necromass (MNC) community characteristics. Compared alone, significantly ( P < 0.05) increased while (40.5% increase) had more pronounced effects than (23.7% increase). Similarly, both MNC content boosted biomass, but impact did biochar. Additionally, markedly aromaticity by 26.6% 0.05), reduced 2.85% > 0.05). Fungi, rather bacteria, played crucial role increasing through their inputs under incorporation. Our results demonstrated that enhanced primarily entombing effect necromass, biochemical protection from recalcitrant aromatic carbon. present findings provide valuable insight practices lead maximize sequestration.

Forest fires are an important disturbance factor in forest ecosystems, and obviously change the soil environment. Arbuscular mycorrhizal fungi, as a medium bridge between vegetation soil, play crucial role mediating plant nutrient uptake regulating productivity, stability, succession of vegetation-soil systems. To investigate effects on community structure diversity arbuscular fungi cold-temperate Larix gmelinii forests, we collected soils from light, moderate, heavy fire forests natural control Greater Khingan northeast China. The was sequenced using Illumina MiSeq technology analyzed correlation with physicochemical characteristics. results showed that contents microbial biomass content (MBC), moisture (MC), total nitrogen (TN), available phosphors (AP) increased significantly (p < 0.05) increasing intensity (from Light to fire), but potassium (AK) decreased 0.05). These changes were not significant. A 14,554 valid sequences all classified into 66 ASVs belonged one phylum, order, four families, genera. genera included Glomus, Ambispora, Paraglomus, Acaulospora, Glomus dominant genus (the five most relative abundances) heavy-fire forests. Non-metric multidimensional scaling (NMDS) analysis affected 0.01). Redundancy (RDA) MBC, SOC, AP composition communities. This study indicated communities through changing parameters (MBC, AP) properties Mountains after provides reference basis for revegetation reconstruction sites.

A "grazing ban" policy has been implemented in some pastoral areas China to fence degraded grasslands for restoration. However, fencing increased grazing pressures unmanaged grasslands. Based on the mechanism of negative edge effect, we investigated whether overgrazing grassland interfered with restoration adjacent grazing-banned by affecting soil properties and microbial community using a sample Hulun Buir Inner Mongolia, order optimize policy. Plant were sampled 30 m away from (UM) (adjacent UM) 30-60 (not (F-30 F-60 m). The species richness diversity plant communities ASV number fungal significantly decreased F-30 UM, Simpson index bacterial compared m. abundance fungi involved organic matter decomposition stress-resistant bacteria increased, while litter UM simplification water total carbon contents can explain variations both results PLS-PM show that changes function guilds may affect those changing contents. These indicate community. should be adjusted periodically avoid effects.
