Livestock producers with open feedlot or cow yards should take time after recent rains to evaluate runoff from lots and yards.  This is a particular concern when manure and soil can move off-site to local streams.  Read more about this issue in the article “Spring Manure Issues for Small Unpermitted Dairies and Open Feedlots.”  It should be noted that in this case we use the term “small” to refer to any open lot facility that is below Large CAFO permit status.  That means all open lots with less than 1,000 head of beef or replacement dairy heifers, less than 700 mature milking cows, or less than 2,500 hogs.

Producers also have the opportunity to evaluate the water quality in streams below lots. DNR has partnered with Iowa State University Extension and Outreach to place water quality test kits in 20 county Extension offices. This test is free and confidential and the only person to see the results is the livestock producer. Information about the testing procedure is found in the fact sheet “Testing the Waters: A Beef and Dairy Producers’ Guide to Check Water Quality Below Open Lots.” and in the video “Clean Water in our Hands: A Guide for Water Testing for Beef and Dairy Producers.”

The fact sheet, video, a list of county Extension offices offering the water quality testing kits, and other resources can be found on the Small Feedlots and Dairy Operations web page on the IMMAG site.


With the rainy season upon us and unfit soil conditions for manure application and spring field work, now is a great time to complete your manure applicator certification requirements for the year. You currently have two options to meet certification requirements: 1) you can contact your ISU Extension and Outreach County Office to schedule an appointment to watch the training DVD or, 2) contact your local DNR Field Office to schedule an appointment to take the certification exam.


In February 2013, ISU Extension and Outreach released a 2-page fact sheet SP0435 “Iowa Strategy to Reduce Nutrient Loss: Nitrogen Practices.” You can download this publication here.


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

The next Livestock and Poultry Environmental Learning Center (LPELC) webinar is scheduled for May 17 at 1:30 p.m. (central). The webinar will feature two beef producers talking about their monoslope buildings for beef production. Ron and Clayton Christensen from Royal, IA, and  Nick Mack, from Watertown, SD, will discuss monoslope barn design, why they chose this type of production facility, management considerations such as bedding, feeding and manure handling, and regulations that affect this type of production system. To access the webinar and to see the schedule of webinars please visit: this site.

The North American Manure Expo is scheduled for August 21, 2013 near London, Ontario. More information will be posted to the IMMAG website as it becomes available.
