Pollution control of swine manure and straw by conversion to Chaetomium cellulolyticum SCP single-cell protein feed
January 1, 1981By M. Moo-Young
Swine manure has a very high pollution potential and obnoxious odor. Large farms particularly are confronted with a manure disposal problem since environmentally acceptable solutions are now required...

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.
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 reduction of swine manure by aeration stripping
January 1, 1980By D. Phillips|N. R. Bulley
A dynamic dilution-to-threshold odour measurement method was used to evaluate changes in odour level downwind from an on-farm anaerobic liquid swine manure tank during short-term aeration. Air...
Odor control in liquid swine and dairy manure with commercial products
January 1, 1980By Robert P. Eastburn|William F. Ritter
In 5 experiments, single or regular addition of liquid polyphosphates (N 10%, P2O5 34%) at up to 4 ml/l to liquid dairy cattle or pig manure (TS 5-7%) did not reduce odour, COD or pH. Single or...
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...
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...
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...
An Anaerobic lagoon for swine manure and its effect on the groundwater quality in sandy-loam soils
January 1, 1977By W. F. Ritter
None available.
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...
