Fungi play a pivotal role as highly effective decomposers of plant residues and essential mycorrhizal symbionts, augmenting water nutrient uptake in plants contributing to diverse functions within agroecosystems. This study examined soil fungi 188 wheat fields across nine European pedoclimatic zones under both conventional organic farming systems, utilizing ITS1 amplicon sequencing. The investigation aimed quantify changes induced by the system their correlation with features climatic factors these zones, spanning from northern southern Europe. zone emerged key determinant shaping overall composition fungal community. Zones characterized moist cool climates, along low levels available phosphorus carbonate, exhibited higher richness. However, variations diversity relative abundances were observed due system-induced changes. Soil pH bulk density identified major factors, for example, they correlate an increase potential pathogenic taxa (Mycosphaerella, Nectriaceae, Alternaria) two Mediterranean growth promoting (Saitozyma, Solicoccozyma) Boreal zone. Organic farming, general, promoted elevated Lusitanian Nemoral highest richness diversity. In terms symbiotrophs pathogens increased zone, while pathotrophs more prevalent Central Atlantic South farming. These findings propose indicators including endophytes climate, content, pH. may favor mycorrhizae drier warmer pH, calcium carbonate density. provides novel insights underscores significance regional edaphic conditions community different systems fields.

Aiming at the problems of serious soil desertification, increased and water loss, reduced soil-available nutrients in agro-pastoral ecotone Northeast Inner Mongolia, this study took corn variety A6565 as planting crop analyzed seven different tillage measures, deep tillage, loosening, shallow rotary heavy harrow, no-tillage, control, combined with straw returning an experimental field Arong Banner. The analysis results are follows: urease activity microbial biomass nitrogen content method straw-returning treatment were higher than other treatments. Compared seedling stage, alpha diversity index bacteria harvest while that fungi was opposite. β comparison showed sampling time main factor affecting bacterial community composition. It found dominant Proteobacteria Actinomycetes, fungus Ascomycetes. Conservation has a positive impact on diversity, which is more helpful for improving quality. All findings may contribute to restricting series important factors sustainable agricultural development, such degradation.
