Micro-/nanobubble oxygenation irrigation, as a novel irrigation technique, has been widely utilized to enhance soil phosphorus availability and maize yield. Nevertheless, currently, most of the studies remain unclear about precise mechanism through which micro-/nanobubble improves Therefore, we established two methods, conventional (CF) (MB), investigate combined effects on enzyme activity, microbial communities, in rhizosphere maize.The results showed that compared CF treatment, MB treatment significantly increased available content alkaline phosphatase activity by 21.3% 15.4%, respectively. Furthermore, influenced bacterial diversity but did not considerably affect fungal diversity. Specifically, regulated community structure altering relative abundances phylum Firmicutes phyla Mucoromycota, Chytridiomycota, Basidiomycota. In addition, reduced complexity network while increasing interaction density among species. Meanwhile, enhanced network. Structural equation modeling indicated primarily promoted regulating diversity, thereby enhancing availability. conclusion, application enhances phosphatasein modulating within rhizosphere, facilitating maize.

The application of phosphate fertilizers significantly influences soil microbial communities and nutrient cycling. Soil enzymes, which are sensitive to levels, play a critical role in metabolism. However, the impact on limitations within metabolism agricultural soils remains poorly understood. In this study, samples were collected from depth 0–20 cm wheat crop subjected three-year field experiment with six different phosphorus (P) rates. β-glucosidase (BG) leucine aminopeptidase (LAP) activities highest under P3 (60 kg P2O5 ha−1) treatment over study period. responses N-acetyl-β-glucosaminidase (NAG) alkaline phosphatase (AKP) increasing P additions varied across years. EES C:N, C:P, vector length greater than 1. characteristics accounted for 70.71% variation enzyme stoichiometry. angle enzymes explained by 0.65 0.73, respectively. Among these factors, ROC exhibited largest direct total effect angle. These research findings offer valuable insights management fertilizers.

Published: July 24, 2024

The application of a diammonium phosphate coating effectively mitigates direct contact between the fertilizer and soil, thus minimizing phosphorus fixation. Humic acid holds pivotal role in augmenting soil quality activating soil’s reserves. Notably, when combined with humic acid, significantly enhances utilization efficiency fertilizer. However, there is paucity literature exploring dynamics nutrient transport paired coated fertilizers. To assess impact on wheat yield enhancement, we conducted pot experiments along leaching ammonia volatilization simulation tests, aiming to elucidate effects this combination transport. study explored three distinct treatments: (CP), (PHA), (CPHA). investigation focused analyzing their impacts yield, volatilization, soil-available phosphorus, nitrate nitrogen, ammonium potassium, as well mobilization calcium magnesium soil.
