Abstract

Odor, hydrogen sulfide (H2S), ammonia (NH3), and volatile organic compounds (VOC, GC/MS analytes) were measured between May and October 2000, and between April and October 2001 at sites representing three different swine production facilities (8000-head nursery, 2000-head finishing, and 3000-head finishing) in southwestern Minnesota. For each facility type, two farms were tested. The paired farms had similar manure storage ponds, production phases, herd sizes, genetics, and diet formulations. A manure storage pond from each pair of farms was selected as treatment (with geotextile cover, Biocap™), and the other as control (without cover). Results showed reductions in odor, H2S, and NH3 flux rates due to the geotextile cover, but performance in reducing odor and H2S deteriorated during the second year of the study. No significant differences in VOC (GC/MS analytes) emissions from covered and non-covered manure storage ponds were observed during the two-year study. Analysis of ambient H2S data suggested the covers were effective in reducing ambient H2S concentrations near manure storage ponds located at the two finishing units. Odor and gaseous flux rates were poorly correlated with relevant manure parameters (NH3-N, sulfides, and VOC).
