how is agriculture contributing to the amount of nitrous oxide?

CO2 absorbs the thermal energy of the sun and does not dissipate for a very long time, trapping heat very much like a greenhouse does (hence, “greenhouse gas effect”). Human activities such as agriculture, fuel combustion, wastewater management, and industrial processes are increasing the amount of N 2 O in the atmosphere. The biggest challenge to reducing nitrous oxide emissions comes from farmers reluctant to reduce the amount of fertilizer they use for fear of diminished yields. In the U.S., agriculture is a much smaller portion of total greenhouse gas emissions, contributing 8.4% of national emissions. Soil Biology and Biochemistry 30, 1885-1893. U.S. Agriculture & Climate. 4. Nitrous oxide is also naturally present in the atmosphere as part of the Earth's nitrogen cycle, and has a variety of natural sources. Nitrous oxide (NO2) depletes the ozone layer and is 300 times more potent than CO2. U.S. nitrous oxide emissions in 2009 were 4 MMTCO 2 e (1.7 percent) below their 2008 total . Research article The global nitrous oxide budget revisited Alfi Syakila1 and Carolien Kroeze1,2* 1 Environmental Systems Analysis Group, Wageningen University, PO Box 47, 6700 AA Wageningen, The Netherlands 2 School of Science, Open University of The Netherlands, PO Box 2960, 6401 DL Heerlen, The Netherlands We present an update of the global budget of atmospheric nitrous oxide (N UCI, others see agriculture as major source of increase in atmospheric nitrous oxide Long-lived greenhouse gas could hinder international climate goals, researchers say Sources of U.S. nitrous oxide emissions include agriculture, energy use, industrial processes, and waste management (Figure 22). Nitrous Oxide Emissions 4.1 Total emissions. The next two most common GHG are methane (CH4) and nitrous oxide (N2O). Overall, nitrous oxide emissions account for roughly 6% of global greenhouse gas emissions. Nitrous oxide is released into the atmosphere through agriculture, when farmers add nitrogen-based fertilizers onto the fields, through the breakdown of animal manure. Approximately 79 percent of all nitrous oxide released in the United States came from nitrogen fertilization. WILLIAMS P.H., JAR VIS S.C., DIXON, E., 1998 – Emission of nitric oxide and nitrous oxide from soil under eld and laboratory conditions. But CO2 is not the only greenhouse gas to worry about. The biggest source of NO2 is agriculture, a method more than 100 …
