Manipulation of Swine Diets to Reduce Odors and Harmful Gaseous Emissions from Manure
Dietary manipulation of sulfur for reduced H2S emission from swine waste
This experiment was conducted to evaluate H2S production rates from nursery pig swine manure stored in simulated waste storage pits as influenced by sulfur content of the diets fed. Waste from six...
Measurement and analysis of atmospheric ammonia emissions from anaerobic lagoons
Ammonia-nitrogen flux (NH3-N = (14/17)NH3) was determined from six anaerobic swine waste storage and treatment lagoons (primary, secondary, and tertiary) using the dynamic chamber system....
Distribution of ammonium-N in the water-soil interface of a surface-flow constructed wetland for swine wastewater treatment
Most livestock wastewaters treated in constructed wetlands are typically rich in ammonium N. The objective of this study was to evaluate the soil-water ammonium distribution and the diffusive flux...
Production of odorous, volatile compounds during composting of hog manure amended with sawdust
Gas chromatographic analysis of volatile fatty acids (VFAs) in mixtures of swine manure and sawdust and in condensate samples of gasses emitted during composting of these mixtures was conducted. Two...
Seepage losses and nitrogen export from swine-waste lagoons: a water balance study
Seepage losses from animal-waste lagoons could affect ground water quality. Water balance methods were used to study seepage and nitrogen export from three swine-waste lagoons in southwestern...
Ammonia emissions from composting hog manure amended with sawdust under continuous and intermittent aeration
Ammonia emissions during composting of hog manure mixed with sawdust were studied in four runs comprising a total of 22 pilot-scale reactor vessels. These four runs extended previous work and both...
Evaluation of vegetative filter strips for swine lagoon wastewater
Vegetative filter strips (VFS), on slopes of 5 and 11%, were used as a means of treating wastewater effluent from the second cell of a swine waste anaerobic lagoon system. Wastewater samples from...
