Nitrogen losses from swine housings
A nitrogen budget procedure was used to estimate the loss of manure N from three swine barns with liquid manure systems. The loss of N was determined as the difference between animal plus feed N...

Pollution control of swine manure and straw by conversion to Chaetomium cellulolyticum SCP single-cell protein feed
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...
Use of nitrification inhibitors and ammonia enrichment with swine manure applications
None available.
Changes in Gas Release Rates and Component Concentrations During Storage of Swine Manure

Odor control in liquid swine and dairy manure with commercial products
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...
Odor reduction of swine manure by aeration stripping
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...
Ammonia losses during sprinkler application of animal wastes
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
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
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...
