USDA has awarded 11 universities $5.3 million to conduct air quality research that focuses on reducing emissions and odor levels from agricultural operations.

Researchers at North Carolina State University will measure ammonia emissions from crop canopies, while the University of Iowa and the University of California Davis will research modeling gaseous emissions from animal housing facilities. Other researchers will study the measurement, control, fate and transport of odor, gases and particulate matter.

The program will help regulatory authorities develop permit options for agriculture producers under the Clean Air Act.
