Estimation of Ammonia and Hydrogen Sulfide Emissions from Cattle Feedlots in Texas
2003 ASAE Annual International Meeting
(2003)
Abstract
A dynamic flow-through chamber system and continuous analyzers were used for on-site measurements of ammonia-nitrogen (NH 3 -N) and hydrogen sulfide-sulfur (H 2 S-S) fluxes from commercial feedlot surfaces in northwestern Texas during two week period in the summer of 2002. Manure pack moisture content, pH, and TKN were measured daily to characterize its relation with NH 3 -N fluxes. The preliminary average NH 3 -N and H 2 S-S flux from the feedlot surface were 1,669 ± 1,212 NH 3 -N µ g/m 2 /min and 1.884 ± 1.497 H 2 S-S µ g S/m 2 /min. Manure pack temperature and TKN was found to have a weak correlation with NH 3 -N flux.
