Technical Abstract: Ammonia is one of 170 compounds detected in livestock manure odor. Ammonia is emitted from surfaces of open, unpaved cattle feedlots and dairy corrals at concentrations of 360-980 g/m**3 as compared to background levels of 1-4 g/m**3 in prior research. Ammonia volatilization losses are reportedly 50% or more of total N excreted from open lot surfaces and 23-70% following field spreading. Approaches to ammonia and odor control include improved manure collection and treatment processes, capture and treatment of odorous gases, and improved dispersion through site selection. Approaches to ammonia monitoring include acidic solution traps, chemoluminescence, and gas chromatography-mass spectrometry.
