Reducing chemical fertilizers in combination with bio-organic can limit the use of while maintaining soil fertility. However, effects combined fertilization on properties, microbial community structure, and crop yield quality are unknown. Using high-throughput sequencing, we conducted field experiments using lettuce plants subjected to five treatments: fertilizer conventional rate (CK), reduction by 30% + 6,000 kg ha-1 (T1), 9,000 (T2), 40% (T3), (T4). Compared CK, T1-T4 had significantly higher pH organic matter (SOM) showed increased richness diversity bacterial community, decreased fungal community. Principal coordinate analysis evidenced that communities CK were distinctly separated. The Kruskal-Wallis H-test demonstrated was more sensitive than fertilizer. Among parameters measured, only TN (total nitrogen) correlated composition. T1 T2 yield. Moreover, characterized reduced nitrate content levels soluble sugars vitamin C lettuce. Overall, application effectively improved fertility, quality. These findings have valuable implications for vegetable safety long-term environmental sustainability.

The process of nitrogen-adaptation root endophytic bacterial rather than phosphorus-adaptation fungal subcommunities construction unveiled the tomato yield improvement under long-term fertilization

Interactions between endophytes (endophytic bacteria and fungi) plants are crucial in maintaining crop fitness agricultural systems, particularly relation to abundant rare subcommunities involved community construction. However, the influence of long-term fertilization on heterogeneous rhizosphere nitrogen phosphorus environments how these conditions affect key root their assembly mechanisms remain unclear. We studied 26th year a field experiment conducted greenhouse with varying levels (CKP0, CKP1, CNP0, CNP1, ONP0, ONP1) assess composition tomato impact yield. employed 16S rRNA fungal ITS region amplicon sequencing investigate endophytic subcommunities, network correlations, core subcommunity structures, species that enhance The results indicated organic manure fertilizers significantly increased soil content, availability (labile P, moderately labile non-labile P). These also affected (based Bray-Curtis distance) processes (βNTI) microbial subcommunities. both bacterial was primarily governed by dispersal limitation, structures being regulated content available (AN) P (MLP). Rare complemented ecological niches co-occurrence network, supporting functions enhancing stability. Nitrogen-adapting provided stronger predictive correlation for yield than phosphorus-adapting Additionally, three genera such as Arthrobacter, Microbacterium, Sphingobium were identified potentially improving improvement. findings revealed distinct fertilization, our understanding better management practices controlling improve intensive ecosystems.

Influence of Agricultural Practices on Bacterial Community of Cultivated Soils

Bacterial communities play an important role in maintaining stable functioning of soil ecosystems, participating decomposition plant residues, accumulation organic matter, formation aggregates and the cycle nutrients. For agroecosystems, diversity microbiocenosis is especially critical because they are essentially less dependent on external control. The agricultural practices used today (plowing, application synthetic fertilizers) can negatively affect richness bacterial communities. solution to this problem may be alternative farming methods preserve structural functional (reduced tillage, conservation no farming). Data composition for further forecasting impact agriculture development effective preserving increasing fertility. This review presents results recent studies Attention mainly paid effects applying inorganic fertilizers structure microbiocenosis; influence system (different cultivation, traditional systems); cover crops crop rotation microbial community soils.
