Purple soils are greatly representative of ecologically fragile in southern China, yet the impact vegetation restoration processes on nitrogen (N) availability purple soil ecosystems is still unclear. In this study, nutrient content, available N fractions (including microbial biomass (MBN), ammonium (NH4+-N), nitrate (NO3--N), and total dissolved (TDN)), enzyme activities urease (URE), reductase (NR), nitrite (NIR)) involved mineralization immobilization were investigated across three vegetation-restoration measures: Camellia oleifera monoculture, ryegrass intercropping, intercropping with weeds. The results showed that monoculture mode considerably enhanced accumulation modified proportion arable land situated slopes, compared to mode, physical, chemical, microbiological properties demonstrated more pronounced effects due measures.

Polycyclic aromatic hydrocarbons (PAHs) are pervasive organic pollutants in coastal ecosystems, especially tidal flat wetlands. However, the mechanisms through which PAHs impact soil bacterial communities of wetlands featuring a simple vegetation structure Yellow River Delta (China) remain largely unclear. In this study, we examined samples from two sites single type (Suaeda salsa) Delta. Specifically, investigated impacts on diversity and composition bacteria high-throughput 16 S rRNA sequencing. significantly increased carbon content but decreased total phosphorus (p = 0.02). PAH contamination notably reduced community α (Shannon index) β diversity. Furthermore, altered relative abundance phyla, classes, genera < 0.05). phyla Acidobacteriota Gemmatimonadota 0.05), while decreasing Bacteroidota, Desulfobacterota, Firmicutes compared to control wetland Moreover, certain properties [total nitrogen (TN), (SOC), (TP), salt (TS)] were identified as key parameters affecting bacteria, with specific being both negatively positively affected by PAHs, SOC, TN. summary, our findings could facilitate identification existing environmental problems offer insights for improving protection management ecosystems China.

Soil organic matter (SOM) is a crucial component of soil, through which physical, chemical, and biological characteristics interact in local context. Within the forest category, conversion natural forests to monoculture plantations has raised concerns Indonesia over loss soil functions, similar agriculture. In forests, SOM can accumulate as part closed nutrient cycle with minimal losses; plantation forestry, decline recovery alternate time, associated larger losses. We reviewed existing studies quantify how shifts from short-rotation (SRPF) affect dynamics, contents, soil-borne pathogens that cause disease. The review combines descriptive quantitative methods (meta-analysis). results show affects C balance, structure water diseases. Contributing factors include reduced diversity plant rhizosphere communities, lower annual litter production, more uniform quality, removal at harvest cycle. Conversion conditions also increases disease incidence by changing control mechanisms.

The conversion of natural forests to plantations affects soil carbon (C) and nitrogen (N) dynamics. However, the underlying microbial mechanisms C N dynamics caused by forest conversion, particularly functional role ectomycorrhizal (ECM) fungi, remain largely unknown. Here, we investigated root-associated fungal communities, ECM root enzyme activities, mineralization rates in western Sichuan subalpine coniferous forest. Soil communities were determined high-throughput Sanger sequencing, respectively. surface enzymes used assess function, while enzymes, mineralization, evaluate function. Our results showed that clearing converting them led lower organic (SOC), total (TN), pH, which drove changes saprophytic (SAP) communities.

In this study, we analyzed rhizosphere soil nutrients, characteristics, hormone metabolome changes their interactions of Casuarina equisetifolia (C. equisetifolia) with the increase number. The results found that C. root was significantly inhibited, height dwarfed biomass reduced as number increased. Secondly, caused a decrease nutrient transformation capacity, significant total available content. Analysis indexes showed resulted nitrogen, phosphorus, potassium content, activity resistance, photosynthetic capacity leaves. Hormone analysis critically affected accumulation five characteristic hormones leaves, which salicylic acid 2-O-β-glucoside (SAG), 2-oxindole-3-acetic (OxIAA), trans-zeatin-O-glucoside (tZOG) gibberellin A3 (GA3) content decreased while abscisic (ABA) increased significantly. conclusion, lowered equisetifolia, inhibited growth, hindered uptake transportation by root, thus led to leaves SAG, OxIAA, tZOG, GA3 synthesis ability decreased, ABA accumulated large quantities, resistance photosynthesis impeded.
