In global drought-prone cotton-growing (Gossypium hirsutum L.) areas, saline water irrigation has become a key strategy to alleviate the shortage of freshwater resources. Against this backdrop, synergistic effect mineralization degree (MD) and sodium adsorption ratio (SAR) on rhizosphere microecological regulation mechanism remains unclear. To address issue, study constructed an experimental framework interaction between MD SAR, aiming explore their effects bacterial community structure in cotton soil environment. The type area is saline–sodic sandy loam. design, three levels (3 g/L, 5 7 g/L) were set, under each condition, SAR (10 (mmol/L)1/2, 15 20 (mmol/L)1/2) arranged. addition, local was used as control group (CG), resulting total 10 treatment schemes. aim investigate varying communities results indicated that could enhance diversity richness alter its structure. Under with 3 g/L reached peak levels. Compared CG, Chao1 index significantly increased by 260 units, while Shannon 0.464. When does not exceed reducing can network stability community, thereby synergistically promoting accumulation nutrients. environmental factors driving changes mainly include moisture content, nitrogen, nitrate organic carbon. concentrations available phosphorus, potassium 19.66%, 26.10%, 89.41%, 49.76% respectively (p < 0.05). This provides theoretical basis for sustainable microbial strategies saline–alkali fields at level, offers new perspective revealing mutual feedback assembly environment conditions. From practical perspective, research valuable hands-on experience optimizing agricultural ecological management loam soils, contributing development agriculture such lands.

ABSTRACT Soil microbial communities provide numerous ecosystem functions, such as nutrient cycling, decomposition, and carbon storage. However, global change, including land‐use climate changes, affects soil activity. As extreme weather events (e.g., heatwaves) tend to increase in magnitude frequency, we investigated the effects of heat stress on activity respiration) that had experienced four different long‐term intensity treatments (ranging from extensive grassland intensive organic conventional croplands) two conditions (ambient vs. predicted future climate). We hypothesized both land use would reduce respiration (H1) experimental (H2). this be less pronounced soils with a history high‐intensity (H3), higher fungal‐to‐bacterial ratio show more moderate response warming (H4). Our study showed was reduced under high (i.e., −43% between cropland) (−12% comparison ambient Moreover, increased overall (+17% per 1°C increase), while increasing strength (−25% slope reduction). In addition, biomass low‐intensity grassland) enhanced stress. These findings change may compromise well their heatwaves. particular, are able respond additional stress, heatwaves, potentially threatening critical functions driven by microbes highlighting benefits sustainable agricultural practices.

Organic fertilizers, such as spent mushroom substrate (SMS), improve soil fertility, but studies comparing their effects on different agricultural soils are limited. In this study, the of standard, SMS and composed fertilizers from conventional-integrated, organic biodynamic farming were investigated. Soil samples analyzed for microorganisms activity β-glucosidase (β-GLU), β-1,4-N-acetylglucosaminidase (NAG), urease (URE), arylamidase (ARN), phosphatase (PHOS), acid (PAC), alkaline (PAH) arylsulphatase (ARS). Biodynamic showed highest microbial counts enzyme activities, followed by conventional soils. significantly increased number especially in Seasonal variations affected all most enzymes soils, except NAG stable throughout year, indicating greater stability. This study concludes that activities respond differently to fertilization depending type, with demonstrating beneficial tested

Introduction Soil has the highest carbon sink storage in terrestrial ecosystems but human farming activities affect soil deposition. In this study, land cultivated for 70 years was selected. The premise of experiment that could be finely categorized by subtype classification. We consider bacterial community and organic (SOC) deposition differently three subtypes albic black soils. Methods Ninety samples were collected structure analysed high-throughput sequencing. Relative changes SOC explored content association with concentrations. Results results showed effects on communities differed among subtypes. Carbohydrate (COC) concentrations significantly higher gleying than typical meadow RB41 , Candidatus-Omnitrophus Ahniella positively correlated total (TOC) shallow soil. Corn soybean rotation have a positive effect sinks ecosystems. Discussion present study provide reference rational use to maintain sustainable development also cycle earth.

Crop rotation is a sophisticated agricultural practice that can modify the demographic structure and abundance of microorganisms in soil, stimulate growth proliferation beneficial microorganisms, inhibit development harmful microorganisms. The stability rhizosphere microbiome crucial for maintaining both soil ecosystem vitality crop prosperity. However, effects extended garlic‒maize on physicochemical characteristics garlic its remain unclear. To investigate this phenomenon, samples from were collected across four different lengths garlic–maize rotation. There notable positive associations between total nitrogen phosphorus contents duration Prolonged could increase maintenance α diversity. number years organic carbon (SOC) content emerged as principal determinants impacting evolution bacterial community structure, with SOC playing pivotal role sculpting species diversity within community. Additionally, remains predominant shaping root-associated community's β-nearest taxon index. these factors do not have effect fungal inhabiting rhizosphere. In comparison monoculture, amplify interconnectivity intricacy microbial ecological networks. Long-term further maintain networks interactions communities. It enlist plethora Bacillus to form biological barricade aids safeguarding against encroachment by pathogenic fungus Fusarium oxysporum, consequently diminishing disease incidence. This study provides theoretical foundation sustainable through long-term maize. Our research results indicate maintains stable microecology. compelling evidence microbiota stability, emphasizing importance cultivating specific enhance strategies farming, thereby promoting sustainability agriculture.
