Management Strategies to Mitigate N2O Emissions in Agriculture

Life, Год журнала: 2022, Номер 12(3), С. 439 - 439

The concentration of greenhouse gases (GHGs) in the atmosphere has been increasing since beginning industrial revolution. Nitrous oxide (N2O) is one mightiest GHGs, and agriculture main sources N2O emissions. In this paper, we reviewed mechanisms triggering emissions role agricultural practices their mitigation. amount produced from soil through combined processes nitrification denitrification profoundly influenced by temperature, moisture, carbon, nitrogen oxygen contents. These factors can be manipulated to a significant extent field management practices, influencing emission. relationships between occurrence regulating it are an important premise for devising mitigation strategies. Here, evaluated various options literature found that effectively reduced intervening on time method N supply (30–40%, with peaks up 80%), tillage irrigation (both non-univocal way), use amendments, such as biochar lime (up slow-release fertilizers and/or inhibitors 50%), plant treatment arbuscular mycorrhizal fungi 75%), appropriate crop rotations schemes integrated nutrient (in way). conclusion, acting (fertilizer type, dose, time, method, etc.) most straightforward way achieve reductions without compromising yields. However, tuning rest (tillage, irrigation, rotation, principles good also advisable, fetch abatement vs. risk unexpected rise, which incurred unwary management.

Global Patterns and Drivers of Soil Dissimilatory Nitrate Reduction to Ammonium

Environmental Science & Technology, Год журнала: 2022, Номер 56(6), С. 3791 - 3800

Dissimilatory nitrate reduction to ammonium (DNRA), the nearly forgotten process in terrestrial nitrogen (N) cycle, can conserve N by converting mobile into non-mobile avoiding losses via denitrification, leaching, and runoff. However, global patterns controlling factors of soil DNRA are still only rudimentarily known. By a meta-analysis 231 observations from 85 published studies across ecosystems, we find mean rate 0.31 ± 0.05 mg kg–1 day–1, being significantly greater paddy soils (1.30 0.59) than forests (0.24 0.03), grasslands (0.52 0.15), unfertilized croplands (0.18 0.04). Soil was enhanced at higher altitude lower latitude. positively correlated with precipitation, temperature, pH, total carbon, N. Precipitation main stimulator for DNRA. Total carbon pH were also important factors, but their effects ecosystem-specific as stimulates forest soils, whereas soils. Higher temperatures inhibit decreasing carbon. Moreover, nitrous oxide (N2O) emissions negatively related Thus, future changes climate land-use may interact management practices that alter substrate availability and/or enhance positive on conservation N2O emissions.
