Odor initiatives in Iowa

by Jeff Lorimor, extension agricultural and biosystems engineer

Odors have become an important factor of the environmental effects of livestock operations. Two separate odor control programs now exist in Iowa.

Iowa Odor Control Demonstration Project
Funded by 1996 and 1997 Iowa Legislatures, this program is administered by Iowa State University. It enlists producers of all species who are willing to implement known odor control technologies and demonstrate them to others. The program provides up to 50 percent cost share to those producers in return for the producers allowing field days and site visits. This program will have about 80 demonstration sites around the state by next summer.

NPPC Odor Initiatives
The second program, funded by the National Pork Producers Council (NPPC), is a two-part national initiative. The first part of the initiative is to support research on innovative odor reducing methods. Moneys will be awarded based on grant proposals much the same way that universities support research. In the second part of the NPPC initiative, teams of Extension, NCRS, and private consultants will do detailed evaluations of the producer's facilities and management. Odor and manure liquid samples will be collected for analysis. The objective is to help the producer pinpoint where the greatest potential for odors is and suggest ways to minimize odor. A standard evaluation instrument and procedures will be pilot tested on six sites in each of four states (Minnesota, Iowa, Missouri, and North Carolina) this fall. The program will be available to producers starting in March, 1998.
