Technical Abstract: Managing animal production systems to reduce environmental impacts is most difficult for air quality. Water and soil quality responses to animal production can be managed through planning and understanding the risk of spills, overapplication, or improper use of manure. Escape of gaseous or particulate material into the atmosphere from all phases of animal production is more difficult to quantify, and the current body of knowledge contains a wide variation in the observed values of all gases. To address this problem will require the development of tools that can more accurately measure the concentrations of all of the gases in the atmosphere and couple these measurements with greatly enhanced atmospheric transport models so that a more accurate emission model can be developed.
