The interactive effects of environmental heterogeneity caused by forest gaps and ectomycorrhizae on fungal community characteristics remain insufficiently explored. To address this knowledge gap, we established a three-year field manipulation experiment in Picea asperata (Picea Mast.) plantation located the subalpine region western Sichuan, China. Growth bags with three mesh sizes—1000 μm (allowing hyphae), 48 (excluding ectomycorrhizae), 1 both)—were placed across (closed canopy, gap edge, center) to investigate how disturbances influence soil communities via changes ectomycorrhizal hyphal turnover alongside physicochemical properties. Soil α-diversity was significantly lower under closed-canopy conditions than at centers remained unaffected treatments. Particularly, species diversity increased 9%, phylogenetic 10% compared closed canopy. In contrast, β-diversity responded both ectomycorrhizal/hyphal treatments (R2 = 0.061; p 0.001) positions 0.033; 0.003).

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 pH is crucial to soil health, influencing nutrient availability, microbial activity, and plant growth. This review aims assess the adaptability of under changing conditions by analyzing natural human factors. Information was gathered from various sources, including peer-reviewed articles, field studies, recent advances in science. The study explores how factors such as parent material, climate, vegetation establish baseline pH, while activities intensive farming land-use changes further modify it, often leading acidification or alkalinization. Traditional management methods like lime application, organic amendments, crop rotation are reviewed for their effectiveness stabilizing limitations varying conditions. also modern technological innovations precision agriculture, which uses sensors variable rate technology targeted management, biological approaches, inoculants, enhance cycling matter decomposition. Integrating these traditional contemporary approaches essential sustainable long-term productivity. findings highlight need a holistic approach that combines historical knowledge with emerging technologies promote agricultural practices environmental conservation.
