In May the newsletter focused on resources available for regulatory compliance and stewardship for open feedlots. The goal was to use the June/July newsletter to identify resources for compliance and stewardship for confinement feeding operations, all to help you prepare for inspections by DNR. However, due to excessive rainfall in many parts of Iowa this newsletter will focus on manure management strategies to employ during excessively wet weather.
This information will discuss practices prior to rainfall events and post-rainfall management strategies. We fully recognize that due to the extended period of wet weather, the strategies employed prior to a rainfall event may be a moot point for some areas of the state.
Prior to impending heavy rains, or repeated rainfall:
After heavy rains or excessive rainfall:
One area of concern for runoff that we don’t often think about is feed storage areas. Keep mixing and loading areas clean by pushing feed spills back into commodity storage. Only uncover the immediate need for feeding when feeding covered feedstuffs. Check for silage leachate and direct any runoff away from streams and road ditches.
Because soils are already saturated and application will be difficult if not impossible, be sure to work with DNR to find alternative measures if you think your outdoor storage structure will overtop. Land-application, even on saturated soils will be preferable to overtopping earthen basins or lagoons as overtopping can sometimes cause a blowout of the entire storage structure. Also be sure to have additional locations identified that may better allow manure application in wet weather and include those emergency locations in your manure plan prior to actual land application.

The IMMAG Events page is a compilation of manure management related events. Please check the events page often for new listings.
Plan to attend the 2014 Manure Expo Valuing Manure and the Environment, near Springfield, MO on July 8 and 9. This is a great event to see manure equipment in action, listen to current research on manure issues and network with industry representatives.
Finally, I just want to share a quick personal note about me and my position at ISU. On June 1st I became the Extension Field Agronomist for 9 counties in NC Iowa. I will no longer be coordinating the Manure Applicator Certification program, but I will still manage the IMMAG newsletter and the IMMAG web page and work on general manure and agronomic issues. My email address remains the same, but my campus phone will cease to exist in the next week or so. I have shared my new phone number below. Next month I will share a list of ISU experts that you can contact as needed, but feel free to contact me and I will get you to the right folks for assistance.
