Straw incorporation into soil contributes significantly to the sustainable development of agriculture. To investigate impact tobacco straw returns on a tobacco–rice replanting system, we designed an experiment with two return levels and control group: T1 (full return), T2 (root CK (no return). Over three-year field in rice fields South China, assessed effects quality, microbial diversity, dry matter accumulation, yield composition rice. The results demonstrated that returning effectively enhanced by positively influencing various physical, chemical, biological properties. Compared those treatment, as porosity increased from 9.0% 12.4%, mean weight diameter aggregates substantially increased, ranging 28.7% 45.2%. There were significant increases organic matter, total nitrogen, alkaline dissolved nitrogen. Soil sucrase activity between 29.8% 44.9%, urease 4.3% 62.2% over three consecutive years return. diversity index fungi increased. Additionally, markedly, 1.8% 5.1%. Overall, enhancement effect surpassed T2. According our comprehensive analysis, was found enhance physical properties soil, elevate enzyme activity, increase abundance microorganisms. Consequently, this practice led improved reduction agricultural waste output. represents clean dependable approach rice-cultivated areas improve health productivity.

As an important cash crop, Nicotiana tabacum's yield and quality are influenced by various factors, yet the correlations between its health status, microbial community, environmental factors remain largely unexplored. In this study, we analyzed diversity of tabacum rhizosphere microbiomes using ITS rDNA sequencing under different conditions. Compared with soil associated healthy tabacum, alpha beta eukaryotic community decreased in diseased indicating a decline abundance composition. soil, exhibited looser structural networks, assembly process both communities predominantly governed stochastic processes. Soil element measurements correlation analyses identified pH, manganese, copper as key status tabacum. A machine learning model incorporating major phyla was developed to predict achieving high accuracy 93%. These findings collectively offer comprehensive insights into relationship conditions, community.

In this study, the effects of different modifiers on rhizosphere soil microorganisms, their functions, and properties continuous tomato cropping were investigated. Nine amendments selected to treat from a 14-year system. Tomato yield, soluble solids, physical chemical properties, enzyme activities measured. Changes in microbial community structure function determined by metagenomic sequencing, correlation with environmental factors was analyzed. The results showed that among nine amendments, combination farmyard manure + Bacillus subtilis Trichoderma harzianum (T2) plant-derived straw decomposed (T3) had most significant effects. hydrolyzable nitrogen, available phosphorus, potassium, organic matter, total nitrogen contents phosphatase significantly increased under T2 T3 treatments. Compared CK treated T2, alkali-hydrolyzed 34.46%, 41.84%, 52.44%, 45.01%, 24.5%, 41.18%, respectively. also changed significantly. relative abundance Proteobacteria, Chloroflexi, Bacteroidota Hyphomicrobium, Rhodomicrobium, Rhodoplanes compared control. mainly enriched two pathways amino acid metabolism carbohydrate metabolism. Among them, six such as bacterial chemotaxis. three glutathione A analysis pH, phosphatase, catalase key affecting changes. treatment farm manure/plant-derived harziensis improved environment, crop clarified functional mechanisms community, provided practical solution problem degradation agriculture monoculture.
