npj Climate and Atmospheric Science, Journal Year: 2022, Volume and Issue: 5(1)

Published: June 2, 2022

Abstract The use of nitrogen fertilizers in agriculture produces significant quantities nitrogenous gases including ammonia, nitric oxide, and nitrous oxide. Through better farmland management practices, the emission can be reduced while realizing clean water environment climate-smart agriculture. In this article, we first provided an overview international movements on reducing gas emissions from farmlands. Then, summarized effect agricultural practices efficiency for various crops, evaluated their emissions. results indicated importance implementing site-specific sustainable to enhance efficiency, thus mitigate We also addressed impact activities cropland cycles, highlighted need perform systematic trade-off evaluations with a well-defined scope maximize environmental benefits maintain ecosystem services. Lastly, proposed three priority directions by moving toward low-emission

Effect of antibiotic perturbation on nitrous oxide emissions: An in-depth analysis

Critical Reviews in Environmental Science and Technology, Journal Year: 2024, Volume and Issue: 54(22), P. 1612 - 1632

Published: April 16, 2024

Agricultural practices such as extensive manure application (containing residual antibiotics) fertilizer can also contribute to antibiotic pollution in soil, besides nitrous oxide (N2O) emissions. This dual impact designates certain agricultural soils hotspots for heightened N2O emissions and pollution. Nevertheless, our understanding of the repercussions residues on underlying mechanisms remain elusive. comprehensive literature review investigated recent research findings regarding contamination its influence microbial production consumption. We scrutinized published data field experimental monitoring results analyze prevalence temporal variation Chinese soils. By analyzing 482 log response ratio (lnR) datasets obtained from 41 independent articles, we established that quinolones (QNs) significantly (p < 0.05) boost Conversely, cycloheximide aminoglycosides (ARs) demonstrated notable inhibitory effects. Antibiotic at concentrations within 1 ppm promoted soil emissions, whereas exceeding 10 (95% CI > 0) inhibited Subsequently, changes oxidation-related microorganisms (AOM), nitrite-oxidizing bacteria (NOB), comammox bacteria, denitrifying well dissimilatory nitrate reduction ammonium (DNRA) anammox processes under stress. Antibiotics unequally affect Our offer valuable insights into complex relationship between antibiotics contributing a better environmental consequences systems.

Land–Water Transport and Sources of Nitrogen Pollution Affecting the Structure and Function of Riverine Microbial Communities

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(7), P. 2726 - 2738

Published: Feb. 6, 2023

The characterization of variations in riverine microbiota that stem from contaminant sources and transport modes is important for understanding biogeochemical processes. However, the association between complex anthropogenic nitrogen pollution bacteria has not been extensively investigated owing to difficulties faced while determining distribution contaminants watersheds. Here, we employed Soil Water Assessment Tool alongside microbiological analysis explore microbial characteristics their responses patterns. Significant communities were observed sub-basins with distinct land–water modes. Point source-dominated areas (PSDAs) exhibited reduced diversity, high number denitrification groups, increased cycling compared others. negative relative deviations (−3.38) measured simulated nitrate concentrations PSDAs indicated removal was more effective PSDAs. Pollution also closely associated microbiota. Effluents concentrated animal feeding operations primary factors relating compositions balanced areas. In nonpoint areas, septic tanks become most relevant community structures. Overall, this study expands our knowledge regarding biogeochemistry catchments beyond by linking specific scenarios microorganisms.

Climate change and anthropogenic nitrogen addition alter the soil physicochemical properties microbial activity in oligotrophic forest soil. Unbalanced non-selective fertilizer application is lost as gas emissions (N2O, NO) also contributed to eutrophication through NO3− leachate. Similarly, infiltrates contaminated drinking water sources lead human thyroid dysfunction. In order protect depleting timber growth due deficiency increasing ecological concerns from misapplication, we reviewed effects of different synthetic forms levels on biogeochemical process. this review, focused most recent findings research articles, review meta-analyses followed complementary insights agricultural so that may be able highlight how these observations contribute understanding cycle.

Nitrogen (N) fertilizer incorporation of efficiency enhancer is a well-established practice aiming at reducing N loss while enhancing crop yield. However, the effect different kinds on use (NUE) and gas are rarely compared poorly comprehended. Here, we conducted field experiment involving combination urease nitrification inhibitor (NI), biological eugenol (DE) bioploymer poly-glutamic acid (PG) their combinations (NI + PG, NI DE, PG DE) to evaluate effects yield, NUE, NH3 volatilization greenhouse emissions (GHGs). Results indicated that NI, significantly enhanced uptake NUE. DE all effective in N2O emission, averagely decreased by 11.13%, 6.83%, 8.29%, respectively, 11.15%, 4.32%, 8.35%, have no significant CO2-C CH4-C fluxes, except increases emission thus global warming potential. The these three enhancers has multiply maize NUE loss. These findings help screen can be more effectively utilized agricultural practices contribute application strategies within systems.
