Evaluation of Alternative Approaches to Control of Odors from Animal Feedlots,

摘要

Alternate techniques for the control of odors from a cattle feedlot were evaluated at a southeastern Idaho site. Three separate odor sources were present:the feedlot surface,the runoff collection and storage ponds,and a potato waste storage pit. Sodium bentonite, ODOR CONTROL PLUS,and the two natural zeolites were found to consistently reduce the rate of ammonia release from the treated areas when compared to nearby untreated areas. Two materials were added to the feed ration as potential odor control techniques. Neither material proved effective based upon the ammonia release rate or the odor intensity measurements made. The spray system was also used to spray a dilute potassium permanganate solution;however,more data will be required to substantiate the results.
