(Des Moines)--Several livestock producers, including one in Kossuth County, have been fined by the Iowa Department of Natural Resources in recent weeks for failing to comply with manure management requirements, according to DNR records.
Most of the violations pertained to required annual updates of manure management plans, which determine how much manure can be applied to fields to avoid excessive application. That can increase the likelihood of stream pollution.
The livestock producers are also required to sample field soil every four years to develop a phosphorus index that helps determine application rates.
Cory Dornbier of Wesley operates two confinement buildings with 3,720 swine. Dornbier was fined $3,000 for five late filings of manure management plan updates from 2013 to 2022.
