Understanding health-related microbial, odor, and ammonia fate following swine lagoon wastewater application by center pivot irrigation
February 20, 2007By Jeanette Thurston-Enriquez
Microorganisms are present in animal wastewater. These microorganisms may include those important in human and animal disease. Animal wastewater may also contain ammonia and compounds that produce...

Assessing the impact of swine sulfur intake from drinking water on odor and gaseous emissions and manure nutrients
February 12, 2007By Bernardo Predicala
To assess the impact of inputs to the pig on air quality and manure management, a study was conducted to assess the effect of varying sulfate levels in drinking water on odor and gaseous emissions...

Macrolide, lincosamide, and streptogramin B (MLSB) resistance in soils amended with swine manure
February 1, 2007By Julie Zilles
The land application of treated swine manure has been proposed to contribute to the spread of antibiotic resistance, but this possibility has not been confirmed. In this work we measured antibiotics...

Identifying the Genetic Profile of the Salmonella-carrier Pig to Improve Food Safety and Decrease Pre-Harvest Disease
February 1, 2007By Shawn Bearson
Pigs that shed Salmonella in their feces are an animal health issue, a food safety problem and an environmental contamination risk. Our research program investigates the undesirable carrier state of...
Using a chemical equilibrium model to predict amendments required to precipitate phosphorus as struvite in liquid swine manure
January 1, 2007By Buchanan
Precipitation of phosphate minerals from liquid swine manure is an established means of
reducing the orthophosphate (OP) concentration. This project investigated the usefulness
of a chemical...
Use of Anaerobically Digested Swine Manure as a Nitrogen Source in Corn Production
January 1, 2007By John E. Sawyer
Swine (Sus scrofa) manure is an important source of N for crop production. The processing of manure in an anaerobic digester for biogas production is only a partial manure treatment process and is...
Soil microbial community composition and structure: residual effects of contrasting N fertilization of swine lagoon effluent versus ammonium nitrate
January 1, 2007By K. Iyyemperumal and W. Shi
Land application of swine lagoon effluent (SLE) often changes soil pH and the concentrations of nutrients and trace metals. We hypothesize that fertilization-associated alteration in soil properties...
Simulating management effects on crop production, tile drainage, and water quality using RZWQM-DSSAT
January 1, 2007By L. Ma USDA-ARS
The objective of this study was to explore if more crop-specific plant growth modules can improve simulations of crop yields, and N in tile flow under different management practices compared with a...
