Ammonia losses during sprinkler application of animal wastes
January 1, 1980
A model for predicting ammonia losses during sprinkler application of animal wastes was developed. These losses are important because of the cost of nitrogen as a fertilizer and because it is a...
Odor and water related nuisances from swine facilities in Ohio
January 1, 1980
Descriptions of 5 pig farms giving rise to complaints of odours and water pollution are given. Legal action and the fines levied are discussed. Methods of solving nuisance problems are noted, and design and management criteria for avoiding them are suggested.

A scrubber to reduce livestock confinement building odors
January 1, 1979
The effectiveness of a cross-flow, packed-bed, wet scrubber for particle, ammonia, and odour removal from swine confinement building exhaust was evaluated. A prototype was designed to study the...
Soil carbon, nitrogen and phosphorus contents in maize plots after 14 years of pig slurry applications
January 1, 1979
Excessive applications of liquid pig manure (LPM) could result in nutrient accumulation in the soil, thereby increasing the potential for plant nutrient losses through movement in groundwater. The...
Corn response to six annual Cu-enriched pig manure applications to three soils
January 1, 1978By D. C. Martens
The increasing use of land application of organic wastes presents a potential pathway for metals to enter the environment and cause phytotoxicity. Studies to evaluate the response of corn (Zea mays...
Effect of arsanilic acid in swine diets on fresh waste production, composition and anaerobic decomposition
January 1, 1977By M. C. Brumm
A complete random design experiment was conducted to determine the effect of arsanilic acid in wine diets on fresh waste production and composition and on decomposition of the waste stored in...
Ammonia volatilization from liquid swine manure applied to cropland
January 1, 1977
Field experiments were conducted to determine the effects of rates and methods of liquid swine manure application on volatile NH3-N losses from cropland. A greenhouse study was conducted to determine...
