Evaluating greenhouse gas emissions in an irrigated cropping system
June 13, 2017 by PHSC Org
June 13, 2017, Idaho – Agricultural production in the western U.S. is an important part of the global food supply. However, due to concerns over impacts from agricultural greenhouse gasses on the global climate, there is a need to understand the effect of nitrogen source on emissions from cropping systems in semiarid environments.
In a paper recently published in the Soil Science Society of America Journal, researchers report nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) emissions from a dairy forage rotation (silage corn-barley-alfalfa) in south-central Idaho that received various nitrogen sources, including granular urea, an enhanced-efficiency fertilizer (SuperU), dairy manure, or composted dairy manure.
