Nitrogen application significantly affects microorganisms in agricultural ecosystems. However, it is still unclear how nitrogen soil chemical properties and microbial communities purple mudstone weathering products. In this study, a field column experiment was conducted typical area with four fertilizer gradients of 0 [CK], 280 [N1], 560 [N2], 840 [N3] N kg ha−1. addition decreased the bacterial chao1 value increased evenness index. For both α- β-diversity, effect on bacteria much greater than that fungi. relative abundance Proteobacteria, Gemmatimonadetes, Bacteroidetes, Ascomycota Actinobacteria, Cyanobacteria, Basidiomycota. Both pH TC are most important influencing fungal communities. With increases rate, co-occurrence network complexity then decreased. summary, could change properties, community diversity, composition, Among them, N2 treatment (560 kg∙ha−1) can more effectively stimulate nutrients, enhance complexity, promote further mudstone.

Impact of Fertilization and Seasonal Changes on Paddy Soil: Unveiling the Interplay between Agricultural Practices, Enzyme Activity, and Gene Diversity

Agriculture, Journal Year: 2024, Volume and Issue: 14(8), P. 1424 - 1424

Climate change and soil acidification are critical factors affecting crop production quality. This study comprehensively analyzed the impact of fertilization practices, including conventional (CA), sustainable (SA), unfertilized (BK), on properties, enzyme activities, gene diversity in paddy fields across seasonal changes. Soil pH was significantly influenced by fertilization, with higher BK a decrease increased fertilization. activities Biolog EcoPlate™ analysis revealed lowest September, highest December under different practices. Metagenomic showed genetic richness CA soil, variations influencing diversity. From perspective genes species taxonomy, Sorangium cellulosum Anaeromyxobacter sp. were most abundant taxa. annotated CAZy, COG, GO databases highly similar structures among Moreover, origins enzymes linked to specific bacterial contributors. While not all gene’s abundance associated activity, arylsulfatase an obvious correlation. Enzyme proved more sensitive indicators microbial activity than abundance. emphasizes need for rational strategies maintain considering agricultural practices variations.
