Manure Applicator Certification

December 16, 2013

By Angela Rieck-Hinz and Rachel Klein, Department of Agronomy

Iowa State University Extension and Outreach, in collaboration with the Iowa Department of Natural Resources, has scheduled manure applicator certification training for 2014.

Commercial Manure Applicators

Commercial manure applicators can meet annual certification requirements by attending a training workshop at one of 76 locations in Iowa on Tuesday, Jan. 7, 2014. Doors open at 8:30 a.m. and the workshops start at 9 a.m. and end at noon. Commercial applicators planning to attend one of these workshops should register by Dec. 30 at the location where they plan to attend. The law requires commercial manure applicators to be certified prior to handling, hauling or land-applying manure. A complete list of Iowa locations, including one location in Minnesota and two locations in Wisconsin, is available. For those commercial applicators who can’t attend on Jan. 7, other options for certification include: 1) contacting your county extension office to determine dates available for training throughout the year, or 2) contacting you local DNR field office to schedule an appointment to take the certification exam.

Confinement Site Manure Applicators

Confinement site manure applicators can attend training at one of 63 different locations in Iowa in January and February. These workshops are each two hours long to meet certification requirements.  A complete list of training workshops is available. Confinement site applicators are reminded that if they choose to attend training to meet certification requirements, they must attend a two-hour workshop each year of their three-year license, or they will need to take and pass the remedial exam to be eligible to recertify during the next three-year certification cycle. Confinement site applicators can also choose to take the certification exam at the local DNR field office to complete certification requirements.  

Dry Manure Applicator Certification

ISU Extension and Outreach is offering eight workshops for applicators that deal primarily with dry or solid manure. These eight workshops meet certification requirements for both commercial and confinement site applicators. The only difference between this series of meetings and the regular commercial or confinement site applicator workshops is this series is geared more at solid manure handling and research. A list of these workshops is available.
