Enhancing Economic and Environmental Value in Soybean Production through Value-Added Innovation
… nitrous oxide (N₂O) emissions peaked at 80% water-filled pore space (WFPS), carbon dioxide (CO₂) emissions remained substantial across moisture gradients, and methane (CH₄) exhibited complex production-consumption patterns. Microbial community analysis through 16S rRNA sequencing identified …

Denitrification and greenhouse gas emissions from cultivated and wetland alluvial soils
… of different landscape units in an agricultural watershed and quantify the effects of BMPs and organic C amendments on denitrification rates of cultivated lands and restored forested wetlands. N2O, CH4 and CO2 emissions from restored and natural forested wetlands were measured to determine if …

Influence of soil bulk density and matric potential on relative gas diffusivity and urea/nitrate-derived N₂O and N₂ losses
… increased soil bulk density (ρb), increases in water‐filled pore space (WFPS) and reduced gas diffusion into and out of the soil. These changes in soil physical properties increase the potential for N₂O emissions via denitrification from soil due to enhanced anaerobic conditions, especially in …

Impacts of Landscape Position and Nitrogen Fertilizer on Soils, Carbon and Nitrogen Leaching, and Greenhouse Gas Fluxes from Switchgrass Production in South Dakota
… ecological impacts assessed in terms of soils, water, and air quality in the northern Great Plains region of United States of America. The objectives of this study were to (i) evaluate the impacts of nitrogen fertilization rate (N rate) and landscape position on soil pH, soil organic carbon …

Quantifying biophysical and biogeochemical influence on northern high latitudes greenhouse gases dynamics
… and sinks from wetlands (including freshwater and coastal wetlands) and non-wetland (including wet and dry soils) with a newly-developed vertically-resolved soil CH4 model, integrated into ISAM. I calibrated and tested this integrated model with CH4 observations at test sites in the …

Mitigation strategies for nitrous oxide emissions based on fertilization management of irrigated crops in a mediterranean climate = Estrategias de mitigación de óxidos de nitrógeno basadas en el manejo de la fertilización en cultivos de regadío bajo clima mediterráneo
… N ha-1) under different moisture contents, at a water filled pore space (WFPS) of 90% and 40%. In addition the importance of soil type in influencing trace gas fluxes was studied by repeating the laboratory study using a contrasting soil from Scotland. The Scottish soil was agrassland soil (pH …
