Qinghai Lake, the largest inland saline lake in China, plays a vital role wetland carbon cycling. However, structure and function of soil bacterial communities its estuarine nearshore wetlands remain unclear. This study examined effects type depth on diversity, community composition, functional potential Shaliu, Heima, Daotang River using high-throughput sequencing. The results showed that significantly influenced communities. Nearshore exhibited lower diversity 0–10 cm layer, while deeper soils (10–20 cm) greater regional differentiation. Estuarine were enriched with Proteobacteria, Actinobacteriota, Chloroflexi, whereas dominated by Actinobacteriota Cyanobacteria. Functionally, had higher sulfate reduction anaerobic decomposition potential, Desulfovibrio, Desulfobacter, Desulfotomaculum regulating sulfur cycling decomposition. In contrast, nitrogen fixation organic matter degradation, facilitated Rhizobium, Azotobacter, Clostridium, nitrogen-fixing Cyanobacteria (e.g., Anabaena, Nostoc). Microbial metabolic functions varied depth: surface (0–10 favored environmental adaptation lipid metabolism DNA repair strategies for low-oxygen adaptation. These findings highlight spatial heterogeneity their biogeochemical cycles, providing insights into dynamics informing conservation strategies.

Common beans are a vital source of protein, vitamins, and minerals. Increasing common productivity is crucial for improving food security farmers’ incomes globally. This study evaluated the growth yield responses to integrated organic inorganic fertilizers under field conditions at Faculty Agriculture, Kabul University. The trial was repeated over two consecutive growing seasons in 2020 2021, using randomized complete block design with 18 treatments three replications. used included urea (N) (0, 60, 90 kg/ha), diammonium phosphate (D) 50, 100 farmyard manure (O) (0 5000 kg/ha). results show that fertilizers, particularly O5000N60D50, O5000N60D100, O5000N90D50, O5000N90D100, significantly increased parameters. In 2020, grain (p < 0.05) by 75.6, 76.7, 68.4% O5000N90D100 treatments, respectively. O5000N90D50 showed significant increases 94.7, 89.6, 97.9%, strongly correlated SPAD value (r = 0.84), number pods per plant 0.71), seeds pod 0.66) it more 0.91), 0.77), 0.76) 2021. A principal component analysis highlighted effectiveness organic–inorganic fertilizer combinations, enhancing while potentially reducing application. demonstrates integrating enhances sustainable crop reduces negative environmental impacts, regions facing nutrient depletion drought conditions.
