New MMP Short Form Accommodates Producers “Mothballing” their Facilities
A new law passed in 2013, House File 512, allows producers with confinement (totally roofed) facilities who need a manure management plan (MMP) to temporarily downsize their facilities without totally closing them. If they temporarily drop below 500 animal units, they do not need to submit an annual MMP and accompanying fees. However, the revised MMP short form (DNR 542-8162) should be submitted to the appropriate DNR field office to notify DNR of the change in status of the facility. Producers should check the box that says, “I am electing to be a small animal feeding operation,” and provide the requested information under that checkmark. When facilities increase above the 500 animal unit threshold, producers must once again submit MMPs and appropriate fees. Editor’s Note:  The above link to the form takes you to the entire list of DNR AFO Forms, be sure to look for the correct form number in the list

Swine producers and commercial manure applicators need to develop biosecurity plans for hauling manure from facilities with Porcine Epidemic Diarrhea (PED). Please take time to read this article “Managing Porcine Epidemic Diarrhea and manure“ from Michigan State University and discuss appropriate actions with all employees.

And finally, if manure management for wise nutrient use is not enough for you to think about, now we need to think about herbicide carryover in manure from animals fed ditch hay. The University of Minnesota talks about potential herbicide carryover from harvesting and feeding ditch hay and how those herbicides may carry through the manure applied to crop land. See the article “Be Aware of Potential Carryover Concerns when Using Ditch Hay“.


Now is a great time to make-sure your manure applicator certification status is up-to-date. Commercial manure applicators conducting business in Iowa must attend 3 hours of annual training offered at their local County Extension Office, or, must take and pass the certification exam once every year. The exams are only offered at the DNR field offices. Commercial manure applicators who have not met certification requirements yet this year must do so before they can handle, haul or land-apply manure. As of the end of July, we anticipate approximately 400 commercial manure applicators still need to meet certification requirements. Additional information for both commercial and confinement site manure applicators can be found on the IMMAG site at, or on the DNR Web page.


The IMMAG Events page is a compilation of manure management related events.  Please check the events page often for new listings.

The 2013 NDSU Carrington REC Nutrient Management Field Day will be held on August 13 from 9 a.m. to 3 p.m. at the Carrington Research Extension Center, near Carrington, ND.

The North American Manure Expo is scheduled for August 21, 2013 near London, Ontario.

Iowa State University Extension and Outreach will sponsor a Low-Cost Feedlot Effluent Pumping and Flood Irrigation Field Day on August 27 starting at 1 p.m., south of Marcus on the Galles Feedlot.This system is designed to incorporate a pumping system below a settling basin that will move the nutrient-rich effluent away from the road ditch to a nearby crop field. These low-cost pumping systems can provide nutrients and water to the cropland thereby keeping nutrients out of local water sources. This field is sponsored in part by the Water Quality Initiative for Small Iowa Beef and Dairy Feedlot Operations project, supported in part by a Section 319 grant through the IDNR and U.S. EPA, Region 7.

Iowa State University Extension and Outreach, IMMAG and the Iowa USDA-NRCS are offering a one-day Advanced RUSLE2 Workshop on September 26 at the Polk County Extension Office in Altoona.  Participants will learn about using templates and software shortkeys and managing dominant critical area with a primary emphasis on understanding and implementing different conservation practices and use of different tillage implements. You should only plan to attend if you have attended the Introductory RUSLE2 and Iowa P-Index workshop in the past. Workshop requirements and registration details are available at the above link. Registration is limited to 30 people, walk-in registration is not allowed.
