The quality of soil containing heavy metals (HMs) around nonferrous metal mining areas is often not favorable for plant growth. Three types growth promoting rhizobacteria (PGPR)-assisted ryegrass were examined here to treat Cd, Pb, and Zn contaminated collected from a smelting facility. effects PGPR-assisted plants on quality, growth, the migration transformation HMs evaluated. Results showed that inter-root inoculation PGPR increased redox potential, urease, sucrase acid phosphatase activities, microbial calorimetry, bioavailable P, Si, K content. Inoculation with also aboveground parts root length, contents, antioxidant enzyme activities. most significant effect was simultaneous all three PGPRs extraction (%) Cd (59.04-79.02), Pb (105.56-157.13), (27.71-40.79), compared CK control (without fungi).

Abstract Nitrogen (N) and phosphorus (P) losses from farmland pose a significant threat to non-point source pollution in plateau lakes. Reducing nutrient loss cropland is essential for the sustainable agricultural ecological development of The study aimed investigate effects optimizing irrigation fertilization on N P based field experiments density functional theory calculation. findings showed that ditch contributes leaching through their interactions with water colloids, while drip reduces transfer capacity by decreasing intensity volume leachates. Additionally, changing conventional multiple needs corn significantly improved fertilizer efficiency, resulting reductions 25.2–72.4% 24.2–67.6%, respectively. optimization led an 11.3% improvement crop yield. These results contribute better understanding mechanisms which practices affect have implications management Erhai Lake basin. Importantly, this research great significance mitigating ecologically fragile
