Gaseous emissions from livestock facilities represent a concern due to the potential effects of ammonia, hydrogen sulfide,
and odors on environmental quality and human health. The lack of knowledge concerning beef cattle feedlot emissions has been a major
obstacle in the development of emission reduction strategies and accurate emission modeling. Emissions from a 2,000-head research
feedlot in eastern Nebraska were measured in this study using a wind tunnel. Flux rates of ammonia, hydrogen sulfide and odor were
determined to compare the effects of diet and pen cleaning frequency for a beef cattle feedlot. Meteorological parameters and soil/manure
pH, nitrogen content, surface and subsurface temperature and moisture content were also measured to determine the extent to which they
influenced emission rates.
