Abstract Background The temperate grasslands are facing numerous pressures from global change. Despite their essential ecological and economic role, how microbial communities react to multiple varying factors remain obscure. In this study, we simulated three change drivers, i.e., nitrogen deposition (ambient N vs. elevated N, aN eN), precipitation increase precipitation, aP eP), mowing, represented experimentally by clipping (unclipped clipped, uC CL), together in all possible combinations a semi-arid grassland ecosystem. Results Nitrogen addition had negative effects on the richness of bacterial fungal communties, significantly changed structures ( P < 0.05) increased dissimilarities 0.05), while water positive protist stimulated α-diversity under without clipping, which was contrast effect clipped plots. Clipping marginal affected 0.05). A notable interactive structure significant protists were found. Combination with or module aggregation meta-networks also observed between CL, as well eP meta-networks. Bacterial, fungal, varied assembly mechanisms, processes differed response factors. Conclusions Overall, addition, individually and/or interactively, distinct degrees, altered soil interaction, community structure, potential function steppe. These findings enhance our understanding provide scientific basis for managing grasslands, particularly context change's impact ecosystem stability.

Incorporating straw into the soil is a sustainable practice that can mitigate some of adverse effects excessive N fertilization on structure degradation and microbial diversity reduction. This objective this study was to determine combined management (straw return removal) (0, 360, 450, 540, 630, 720 kg ha-1 yr.-1) crop yields, properties, communities in long-term wheat-maize cropping system. The results showed moderate application (N450-N540) with optimized wheat (283.5 ha-1) maize (346.5 whereas higher (N630, N720) led acidification (pH decline 0.51-1.67 units), irrespective management. Straw increased organic carbon (SOC), total nitrogen (TN), nitrate (NO3 --N), available potassium (AK), but decreased ammonium (NH4 +-N). Bacterial at rates rates. Fungal generally under removal, Chaetomiaceae increasing return, Mortierellaceae Trichocomaceae declined high levels. Mantel test strong correlation between pH bacterial diversity, while fungal composition influenced by SOC, TN, NO3 --N.

Elevated atmospheric deposition has acidified European heathland soils, reducing plant and soil biodiversity. Slow‐release silicate rock powders (SRP) are being explored to enhance pH base saturation in these soils. We compared the effects of SRP liming on chemistry, microbiome, vegetation with an untreated control, 5 years after application. established 40 plots, equally divided across a wet dry heathland, where we setup four treatments randomized block design: application 4 metric ton/ha Dolokal (liming), 10 Biolit (SRP, chlorite/muscovite concentrate), Soilfeed K‐feldspar/biotite or no With used doses, applied acid neutralizing capacity (ANC) approximately 70 keq/ha (Dolokal), 35 (Biolit), (Soilfeed). had strongest increasing by about 1 unit 49 65%, largest soils low cation exchange capacity.

ABSTRACT The diversity patterns and drivers of soil microbial communities across spatial distances have been extensively investigated over the recent years. However, whether in surface subsurface soils showed an identical distribution pattern at a small regional scale has not fully confirmed. For this, we linkage between water content (SWC), pH as well nutrient contents bacterial different layers Longmenshan fault zone Sichuan Province, China. Our investigation indicated that were positively correlated with SWC ( P < 0.05), whereas those organic carbon its fractions 0.05). Bacterial community co-occurrence network structures differed significantly layers. Compared to soils, had more nodes, larger diameters, longer average paths. keystone species belonged Rokubacteriales surface, soil, they Chryseobacterium, while no found subsoil. Spatial distance smaller effect (4%–7%) on structure, indicating various factors represent key regulatory for shifts.

Sustainable soil health management is pivotal for advancing agricultural productivity and ensuring global food security. This review comprehensively evaluates the effects of mineral-organic fertilizer ratios on microbial communities, enzymatic dynamics, functional gene abundance, holistic health. By integrating bioinformatics, enzyme activity assays, metagenomic analyses, we demonstrate that balanced fertilization significantly enhances diversity, community stability, resilience against environmental stressors. Specifically, synergistic application mineral organic fertilizers elevates β -glucosidase urease activities, accelerating matter decomposition nutrient cycling while modulating taxa critical transformation pathogen suppression. Notably, replacing 20–40% with alternatives mitigates risks such as greenhouse gas emissions leaching sustaining crop yields. dual approach improves structure, boosts water retention capacity, increases biomass by 20–30%, fostering long-term fertility. Field trials reveal yield 25–40% in crops like rice maize under combined fertilization, alongside enhanced carbon (110.6%) nitrogen content (59.2%). The findings underscore necessity adopting region-specific, strategies to optimize ecological sustainability productivity. Future research should prioritize refining frameworks through interdisciplinary approaches, addressing soil-crop-climate interactions, scaling these practices diverse agroecosystems. aligning policies principles, stakeholders can safeguard health—a cornerstone human wellbeing—while securing resilient systems future generations.

Elemental sulfur is widely used in fungicide applications to control crop diseases agricultural systems, but its effects on soil microbial communities are largely unknown. In China, significant amounts of elemental sprayed annually rubber plantations support performance. To investigate the spraying diversity, composition, interactions, and functionalities plantation soil, samples from Yunnan, South were collected, bacterial fungal analyzed through high-throughput sequencing. Results showed that application did not alter alpha diversity beta community. Notably, disturbed relative abundances Chloroflexi Planctomycetes. Certain bacteria (e.g., Bacillus Sinomonas) thrived under treatment, influencing nutrient cycling. The ecological network analysis revealed enhanced interconnections. Sulfur had a limited impact phenotypes community functions, yet it inhibited compound respiration. These findings indicate can shift composition influence cycling by favoring specific groups. Despite phenotypes, affects key metabolic processes, such as respiration, which vital for health activity. results highlight need sustainable management optimize plantations.
