This study focuses on greenhouse gas (GHG) emission from livestock manure. In addition to the global warming potential of the GHGs (e.g., CH 4, N 2 O, NO, CO 2 ), ammonia (NH 3) emissions contribute to global warming when NH 3 is converted to nitrous oxide (N 2 O). Therefore, this chapter addresses in detail the GHG and NH 3 emissions from
