Smart Fertilizer technologies: An environmental impact assessment for sustainable agriculture

Smart Agricultural Technology, Journal Year: 2024, Volume and Issue: 8, P. 100504 - 100504

Published: July 17, 2024

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.

Mitigation strategies for soil acidification based on optimal nitrogen management

Frontiers of Agricultural Science and Engineering, Journal Year: 2024, Volume and Issue: 0(0), P. 0 - 0

Published: Jan. 1, 2024

● 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 hydrolysis in different farmland soils as affected by long-term biochar application

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Published: Aug. 12, 2022

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.

Effects of Long-Term Organic–Inorganic Nitrogen Application on Maize Yield and Nitrogen-Containing Gas Emission

Agronomy, Journal Year: 2023, Volume and Issue: 13(3), P. 848 - 848

Published: March 14, 2023

A sustainable model of combined organic–inorganic fertilizer application for high maize yields and environmental health is important food security. The short-term organic inorganic fertilizers can improve crop yields; however, the effect different proportions on yield nitrogen gas emissions in a long time series has not been reported. In this study, field experiments DeNitrification-DeComposition (DNDC) simulations were used to study long-term effects substituting with nitrogen-containing emissions. Six treatments included: no (CK); urea (U1); 25%, 50%, 75%, 100% N substituted by (U3O1, U1O1, U1O3, O1, respectively). DNDC was calibrated using data from U1 treatment 2018 2020 validated other treatments. results showed that could effectively simulate (e.g., nRMSE < 5%), soil NH3 volatilization, N2O (nRMSE 25%). addition, (26 years) simulation studies found U1O1 considerably increase ensure stability, which 15.69–55.31% higher than treatment. N2O, NH3, NO descending order > U3O1 O1 U1O3 total decreased 53.72% compared years). Overall, 50% maintain reduce gases, constituting good mode area.
