The meaning of NITROGEN is a nonmetallic chemical element with atomic number 7 that under standard conditions is a colorless, odorless, inert gas, that constitutes 78 percent of the Earth's atmosphere, and that is used especially in the industrial synthe
Nitrogen as a Greenhouse Gas Compounds of nitrogen, and particularly nitrogen oxides NOx, are considered greenhouse gases. Nitrogen is used as a fertilizer in soils, as an ingredient in industrial processes, and is released during the burning of fossil fuels. ...
Nitrous oxideBiosphere-atmosphere exchangeSoil gas fluxNitrogen (N) fertilizer use in managed forest ecosystems is increasing in the United States and worldwide to enhance social, economical and environmental services. However, the effects of N-fertilization on production and consumption of greenhouse ...
Greenhouse gases (GHGs) emissions from livestock systems are important because of their significant contribution to global warming. Nitrogen (N) fertilization can improve system production; however, it alters soil gas emissions. We evaluated soil nitrous oxide (N2O), methane (CH4), and carbon ...
Greenhouse gas emissions from nitrogen fertilizers could be reduced by up to one-fifth of current levels by 2050 with combined interventions Article09 February 2023 Global mapping of crop-specific emission factors highlights hotspots of nitrous oxide mitigation ...
Ammonia and greenhouse gas emissions from a subtropical wheat field under different nitrogen fertilization strategies Minimizing soil ammonia (NH 3 ) and nitrous oxide (N 2 O) emission factors (EFs) has significant implications in regional air quality and greenhouse gas (G... L Shuai,JJ Wang,T...
Nitrous oxide is of particular interest because it is more potent than CO2 as a greenhouse gas and because of its role in the destruction of stratospheric ozone. To understand the potential magnitude of lake N2O production related to atmospheric N deposition, we applied two published methodologies ...
forcing agents (e.g. ozone, aerosol particles) and remove the long-lived climate-forcing agents (e.g. methane (CH4)); NH3also increases the formation of aerosols. In addition, the deposited and applied N into the terrestrial ecosystem alters the carbon (C) exchange and greenhouse gas (GHG...
