Here, we conducted a decade-long experiment involving fungicide application (with or without) nested within a nitrogen (N) addition gradient in a species-rich alpine pasture on the Tibetan Plateau. Soil nematode communities were assessed by Illumina sequencing, and soil multifunctionality was quantified from eight key ecosystem functions. Fungicide application markedly reduced nematode taxonomic and phylogenetic diversity, simplified nematode food webs and co-occurrence networks, and significantly decreased soil multifunctionality. In contrast, N enrichment increased the relative abundance of <em>r</em>-strategy nematodes but had no effect on nematode diversity or soil multifunctionality. No significant N and fungicide interactive effects were detected, suggesting that these two disturbances may act through independent pathways under alpine conditions. Fungicide had strong direct and indirect effects on nematode communities, and the indirect effects were primarily driven by changes in plant diversity and productivity, rather than by soil fungal community characteristics or soil physicochemical properties. Changes in soil multifunctionality were mostly attributed to the fungicide-induced shifts in nematode community composition and network complexity. This is the first long-term field study to jointly assess N and fungicide effects on soil nematodes and multifunctionality, highlighting fungicide use as a greater threat than N enrichment to belowground biodiversity and ecosystem sustainability in alpine grasslands.</div></div>","PeriodicalId":8099,"journal":{"name":"Applied Soil Ecology","volume":"215 ","pages":"Article 106481"},"PeriodicalIF":5.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we investigate the interactions between microplastics and AMF, their consequences on nutrient uptake and community structure, and how these affect the health of terrestrial ecosystems. Microplastics can have a significant impact on soil ecosystems. They exist in various types, shapes, sizes, and concentrations, and exert multiple effects on AMF. Detrimental effects are primarily observed when microplastic concentrations exceed 1–10 % of soil weight. During their degradation, microplastics can release and adsorb toxic pollutants, such as cadmium and lead. Additionally, they can adsorb essential nutrients such as phosphorus and nitrogen, reducing their availability for the plant-AMF symbiosis. Microplastics can alter chemical and physical properties of soil, decrease soil aggregate water stability and air permeability, alter pH levels, as well as affect AMF abundance and composition, their roles, and ecosystem services. However, the extent of these effects may vary depending on the size, type, concentration, chemical composition, and duration of microplastic exposure.

For community structures of soil bacteria and fungi (determined via genetic metabarcoding) and plants (determined via plant species relevés) the effect of fertilization had a stronger effect than that of cutting frequency.

These findings suggest that long-term mineral fertilizer application is a key driver of differences in microbial community structure in grasslands of contrasting management type, and may influence bacterial P solubilisation capacity.

However, the effects of different straw-return methods on the migration and accumulation of ARGs in the soil-plant system remain poorly studied. Returning straw to fields can alter ARG accumulation in plants through modifications to soil microbial community structure and physicochemical properties. Specifically, mulching using crushed straw can mitigate the risk of ARGs spread through elevating soil organic matter (SOM) content and improving soil structure. Meanwhile, straw composting can reduce ARGs accumulation by degrading antibiotic residues and altering microbial communities composition.
