In the North China Plain, it is common for farmers to regularly clear crop residues from their fields. The prevalent practice of fertilization in this region continues depend heavily on use compound fertilizers. Howere , long-term single fertilizer application has become norm present agricultural production, which not only destroys rotation system but also negatively affects soil environment and yields. current knowledge how nutrient deficits affect microbial community structure double-cropping systems still limited. To clarify specific response microorganisms absence key nutrients ecosystems annual double cropping system, study investigated lack essential affected diversity, abundance, functional dynamics soil, designed five treatment methods: (1) CK, nofertilizer treatment; (2) NPK, adequate nitrogen fertilizer, phosphorus potassium (3) PK, deficiency (4) NK, (5) NP, treatment. results showed that two growing seasons, NPK increased yields wheat corn by 16.9% 27.0%, respectively, while NK NP treatments 13.4%, 5.4%, 25.0%, 17.9%, total yield 21.1%. addition, promoted diversity abundance maize, balanced provided more comprehensive nutritional support crops. Compared other nutrient-deficient treatments, substantially bacterial fungal communities (p<0.05). are significantly correlated with physicochemical factors involve organic matter, pH, content, phosphorus, levels. pH primary environmental factor influencing communities.

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.

Organic fertilizer application promotes the prevalence of antibiotic resistance genes (ARGs), yet factors driving temporal differences in ARG abundance under long-term organic remain unclear. This study investigated dynamics diversity and both bulk rhizosphere soils over 17 years (2003-2019), explored microbial evolution strategies, hosts succession influence root exudates on ARGs regulation. The results showed that soil was lower than fertilization, exhibited a decrease then remained stable time. There strong association between host bacteria dominant (p < 0.05). Structural equations demonstrated bacterial community had most pronounced 0.05), metabolites an important mediation effect thereby impacting ARGs. metabolome analysis evidenced significant correlations were found defensive like, luteolin-7-glucoside negatively correlated with tetA(58). These findings provide deeper insights into identify critical colonization soils, providing support for controlling spread agriculture soils.
