Notes
Greenhouse gas emissions are fueling global climate change, with methane and nitrous oxide being the primary agricultural gases emitted. N₂O is an important greenhouse gas ; it is precursor to ozone destroying NO and has a heating capacity 296 times that of CO₂. It has been shown that N₂O emissions correlate to moisture content fluctuations, however emissions from agricultural fields in the semi-arid regions of the Southwest where rewetting events occur regularly are not well established. The scope of this study was to quantify greenhouse gas emissions in correlation to soil moisture fluctuations and fertilizer application. The study was conducted on two pecan (Carya illinoinensis) (Wangenh.)K. Koch) orchards between September 2010-August 2011 on a sandy loam soil (La Mancha) and a silty clay loam soil (Leyendecker), both under
