The presence of excessive algae in water is always considered as a negative factor irrigation. However, the optimal balance between algal removal and retention irrigation when biomass controllable remains unknown. Therefore, this study explores impact low-level (Scytonema javanicum) on soil microbial activity through controlled column experiments. Soil moisture was measured, 16S rRNA gene amplicons sequencing applied to characterize community. Slight community changes indicated no local S. javanicum. Enzyme assays quantitative polymerase chain reaction (qPCR) revealed that improved retention, enhanced nutrient content topsoil. decrease treatment group (from 27.53% 26.42%) significantly reduced (p < 0.05) compared control 27.55% 25.17%), while contents ammonium (NH3-N) total nitrogen (TN) (0.70 mg/kg 0.54 g/kg) were also higher than (0.43 0.49 g/kg). results abundance functional suggested facilitated fixation nitrification. This research offers innovative insights for diversifying sources water.

ABSTRACT Enhancing nitrogen use efficiency (NUE) is widely recognized as an important strategy for both agronomic productivity and environmental sustainability. This study aims to provide a comprehensive analysis of NUE at global country levels, including selected nations such the United States, France, China, India, South Africa. It also examines recent advancements in agricultural practices designed enhance crop yields while minimizing overuse fertilizers. The findings indicated that world some countries, States America, has been increasing with different gradient, resulting decline surpluses contributing pollution these countries over years. In contrast, India Africa have shown increase surpluses. Additionally, enhancing through innovative procedures cutting‐edge technologies importance reducing reliance on heavy applications mitigating their impact. was concluded harmonizing strategies precision agriculture technological can significantly improve preserve health.

The global food supply heavily depends on utilizing fertilizers to meet production goals. adverse impacts of traditional fertilization practices the environment have necessitated exploration new alternatives in form smart fertilizer technologies (SFTs). This review seeks categorize SFTs, which are slow and controlled-release Fertilizers (SCRFs), nano fertilizers, biological describes their operational principles. It examines environmental implications conventional outlines attributes SFTs that effectively address these concerns. findings demonstrate a pronounced advantage including enhanced crop yields, minimized nutrient loss, improved use efficiency, reduced greenhouse gas (GHG) emissions. Nevertheless, amidst benefits, challenges constraints associated with technologies, such as expenses potential specific components, also discussed. A comparative assessment emphasizes importance balanced approach, considering three crucial factors: safety, cost-effectiveness. While no single SFT achieves optimal balance across dimensions, integrating multiple may help mitigate individual drawbacks. Also, financial cost-to-benefit analyses essential gauge applicability diverse cropping environments. Future perspectives shed light emerging innovative approaches overcome prevailing cultivate more impactful role fostering sustainable agriculture.

● Soil acidification is determined by proton production and soil buffering capacity. Cropland mainly caused anthropogenic activities. Nitrogen transformations dominate processes. Acidification stage-specific strategies are needed for managing acidification. Optimizing N rate form highly effective in mitigating a serious constraint to food worldwide. This review explores its primary causes, with focus on the role of nitrogen fertilizer, suggests mitigation based optimal management. Natural leaching weak acid climate conditions, whereas use ammonium-based fertilizers, nitrate removal base cations (BCs) crop harvesting mostly accounts In addition, low capacity, parent materials organic matter content, also accelerates study proposes targeted different stages acidification, which include monitoring carbonate content pH soils > 6.5 (e.g., calcareous soil), alkaline amendments strongly acidic (pH < 5.5) aluminum toxicity risk between 5.5 6.5, decreasing rates supplementing BCs maintain this range, especially Effective involves optimizing fertilizers used, regulating transformation processes, establishing an integrated soil–crop management system that balances

Urea is a commonly used nitrogen (N) fertilizer that contributes to world food production, and there have been increasing concerns about relatively low urea-N use efficiency. Biochar has shown the potential mitigate N loss, but how biochar influences urea hydrolysis underlying mechanisms are still unclear. In this study, long-term biochar-amended upland, paddy greenhouse soils were sampled at depths of 0–20 20–40 cm in Haicheng City, Northeast China. Soil contents, rates (UHRs), total, intracellular extracellular urease activities determined, as well total bacterial ureolytic microbial gene abundance quantified. The results showed increased activity by 32.64–66.39% upland soil 2.90–2.13-fold soil. Both ureases contributed increase activity. However, soil, (+35.07–74.22%) (−40.14–77.68%) responded inconsistently incorporation. Increases ureC copy numbers (2.15- 4.47-fold) (20.93%) implied stimulated microorganisms capable producing urease, liming effect pH (0.11–0.60 units), which optimized reaction, together explained increases We found decreased content was accompanied higher UHR soils, suggesting accelerated exerted negative on content, possibly caused excessive NH 3 volatilization. where not increased, an effective amendment for simultaneously improving content.
