US poultry production emissions examined
Hongwei Xin, professor of agricultural and biosystems engineering, said progress has been made toward collecting baseline data on air emissions from US animal feeding operations, especially for broilers, laying hens and swine.
A new, two-year study of air emissions from twoMidwest turkey production units will get underway in March 2007, funded by a US$500,000 grant from the US Department of Agriculture‘s National Research Initiative on air quality.
The project will continuously measure emissions of ammonia and particulate matter from two mechanically ventilated turkey barns for one year. The measurements will be done at a commercial facility in central Iowa that produces tom turkeys, and at a University of Minnesota research farm near Rosemont, MN, that produces hen turkeys.
The project also will monitor the indoor air quality at several locations in the naturally ventilated section. State-of-the-art mobile air emissions monitoring labs developed by Iowa State University scientists will be used.
“Ultimately, this study will contribute to the advancement of basic science and inventory on air emissions from turkey production facilities and impact the US turkey and agricultural industry by helping sustain its competitiveness and prosperity in the global economy,” Xin said.
