Project Description Odors from pig farms are an issue for many communities and pork producers. The economic importance of the pork industry makes it essential for Minnesota communities to find solutions to odor problems.
Research is needed to quantify odor levels and to evaluate odor control technologies.
Manure storage systems contribute significantly to odor problems. Covering manure storage units has been suggested as an effective odor control strategy, but effectiveness and management need to be tested in field situations. Results Air samples were collected during fall 1996 from 22 manure storage units on 16 different farmsites around the state. Since only a few of the storage units were built with covers, we contacted two Minnesota companies and invited them to participate in the project by installing their covers on manure storage units at a cooperating farmsite. We will make monthly odor measurements from April 1997 through the summer.
