Manure-Phosphorus in Soil: Detection and Mobility of Phytate
June 5, 2007By Shiping Deng
Annual swine effluent application in western Oklahoma for 11 consecutive years did not lead to significant accumulation of soil phosphorus. Similar trend was shown in a century-old field experiment...

Influence of corn co-products on air emissions and nutrient excretionsfrom grow-finish swine
December 12, 2006By Wendy Powers
Corn co-products are an increasingly important alternative to corn in swine diets. While there has been some research to evaluate how these co-products affect pig performance, the effect on air...

Partitioning between pit and wall emission streams of hydrogen sulfide, ammonia, particulate matter, and odor from deep-pit pig finishing facilities for decision support in selecting emission control technologies
December 1, 2006By Larry D. Jacobson
The results of this study show limited benefit to exhausting a portion of air through the pit rather than through the wall for deep-pit pig finishing barns. This conclusion comes from similar indoor...

Developing a Decision Support Tool to Optimize Swine Production Facility Layout to Minimize Downwind Air Quality Impacts
November 13, 2006By Thomas J. Sauer
These model experiments of air flow characteristics suggest that when swine confinement buildings are oriented so that the approaching wind is parallel to the buildings the wind is reduced less than...
