Soil tillage is a critical agricultural practice affecting crop productivity and greenhouse gas emissions. However, farmers hesitate to adopt intensive frequent rotary due problems such as soil compaction yield reduction. A field experiment was conducted for two years qualify the effect of practices on pore structure, carbon sequestration. The treatments included 15 cm (RT15), subsoiling 35 (SS35), 40 (SS40). results showed that increased macropore area by 83.6%-130.7% cumulative volume 53.5%-63.7% in 20-40 layer, compared RT15. As result, SS35 SS40 had higher macro aggregates 2.3%-3.1%, mean weight diameter 12.8%-19.2%, geometric 18.1%-18.3% than Subsoiling significantly organic 28.4%-36.9% sequestration 65.0%-73.6% 10-40 Ultimately, summer maize 2.8% 10.7% RT15, respectively. These suggest appropriate effectively increases changing structure. This study provides an improved understanding response disturbance subsoiling.

Nitrogen is the most limiting factor in crop production. Legumes establish a symbiotic relationship with rhizobia and enhance nitrogen fixation. We analyzed 1,624 rhizosphere 16S rRNA gene samples 113 metagenomic from three typical legumes non-legumes. The microbial community of had low diversity was enriched nitrogen-cycling bacteria (Sphingomonadaceae, Xanthobacteraceae, Rhizobiaceae, Bacillaceae). Furthermore, microbiota exhibited high abundance nitrogen-fixing genes, reflecting stronger potential, Streptomycetaceae Nocardioidaceae were predominant bacteria. also identified helper confirmed through metadata analysis pot experiment that synthesis riboflavin by key promoting Our study emphasizes construction synthetic communities crucial for development efficient fertilizers.

Red-soil sloping farmland in southern China plays a crucial role the local economy and food production. However, improper tillage practices have resulted topsoil degradation deteriorating soil quality. This study investigated changes physico-chemical properties under four methods—cross-slope ridge (RT), down-slope (DT), plastic mulching (PM), conventional (CT)—on red-soil farmland. The applied Soil Management Assessment Framework (SMAF) to assess influence of these on Results indicated that PM can increase total porosity soil, reduce bulk density, simultaneously decrease surface-water evaporation, significantly improving soil’s water-retention capacity. RT improved aggregate formation stability, leading increased macro-aggregate content, mean weight diameter, water-stable stability rates. effectively preserved nutrients like nitrogen organic matter, although lowered pH, potentially causing acidification. demonstrated highest quality, with following. Crop growth positively impacted content showing continuous improvement structure quality (p < 0.05). Priority should be given farmland, followed by CT, while avoiding DT if possible. research furnishes valuable scientific substantiation for selection optimal preservation slopes.
