Iowa State University has conducted extensive research and extension efforts on reducing odor and gas emissions from livestock operations. A new online summary outlines more than 50 items on current or recent research and how Iowa State Extension specialists are working with producers as this research leads to new knowledge and working solutions.

The summary has four main categories:

  • Addressing air quality with a more complete understanding of emissions
  • Addressing odors by feeding innovative animal diets
  • Addressing air quality by building on innovative discoveries
  • Addressing odor through responsive extension and service

From 2003 through June 2008, Iowa State received external grants totaling $6.2 million for projects focusing on air quality and livestock odor. Including grant awards on manure management, the total increases to $7.6 million. Iowa State’s College of Agriculture and Life Sciences also invested $435,000 in air quality and livestock odor research. In 2003-2008 period, 44 externally funded projects addressed research and extension issues on air quality, odor, animal waste and manure management.
