Optimizing the Nutrient Value of Dairy Manure while Minimizing Risk
Take a look at our new video on the Small Feedlots and Dairy Operations page on "Optimizing Nutrient Value of Dairy Manure While Minimizing Risk." In the video, you will have a chance to see some of the systems dairy farmers in Iowa are using to get the most from their manures and help keep Iowa’s waters safe and clean. Give it a watch and get some tips for manure management at your farm ranging to handling lot runoff, storing the manure, or putting your nutrient management plan together.
P.S. While you are there remember, check out "Iowa’s Cattle Producers Protect Water Quality."


photoRunoff Risk Advisory Forecast
The Runoff Risk Advisory Forecast is a map based tool that shows day-to-day risk of runoff occurring. It uses National Weather Service forecast methods that consider precipitation, soil moisture, and individual watershed characteristics to estimate the likelihood of runoff occurring. This tool is currently available as part of Wisconsin’s Manure Management Advisory System.

The National Weather Service (NWS) has published the official request for public comments regarding the expansion of the runoff risk decision support forecast guidance into new areas in the future (NWS Runoff Risk PNS). Supportive public comments could encourage the National Weather Service to support the multi-agency efforts ongoing in WI, MN, MI, and OH as well as new states in the future. If you have comments you would like to share, that can be sent to Wendy Pearson: NWS Central Region Headquarters, Kansas City, MO 64153,

World Antibiotic Awareness WeekAntibiotic Awareness Week
The week of November 16-22 was the World Health Organizations Antibiotic Awareness Week. Over at The Manure Scoop you can read a summary of some work Dr. Michelle Soupir did tracking the transport of antibiotic resistant bacteria in swine manure in a tile drained field after land application. What might this mean for our livestock production systems and in particular manure management in the future?

EPA Nutrient Separation Challenge
photoThe U.S. Environmental Protection Agency has launched a “Nutrient Recycling Challenge.” Every year, livestock producers manage more than one billion tons of manure – manure that is filled with nitrogen and phosphorus that plants can use. However, as manure is mostly water moving these nutrients to areas where they are needed can in some instances be expensive.

Thus, as part of this challenge, the EPA is collaborating with pork and dairy producers, the USDA, and environmental and scientific experts to host a competition to find technologies that can recycle nutrients from livestock manures and create valuable products. The Nutrient Recycling Challenge is seeking ideas for cost-effective technologies that extract nutrients (nitrogen and/or phosphorus) from cow or hog manure and concentrate them into a usable and potentially marketable form.

For more information visit the web site to see the time lines of the various components of the completion.

Iowa DNR Spill Number
Manure application season is here, have you updated the spill number in your phone? If you have not already my sure you get that number updated in your phone or where you keep it posted in your manure application tractor so you’ll have it handy should you need it this manure application season. The new number is: 515-725-8694.


photoFall manure application season is here, are you certified? Just a reminder that if you are in the business of applying manure (a commercial manure applicator) or have more than 500 animal units and apply manure from your  farm (a confinement site applicator) you must complete your annual manure application certification training. You can get certification by: 1) contacting your County Extension Office to make an appointment to watch the appropriate training video; 2) contacting your local DNR field office to schedule an appointment to take the certification exam; or 3) completing your training on-line!

The MAC on-line option provide similar topics and information as the in-person and DVD training, but will be available to the applicator from the comfort of their own home or office. To utilize the on-line option, the applicator will need a computer, smartphone, or other internet capable device and an internet connection that will support streaming video. To find the online training site, please go to MAC E-Learning. Remember, taking the on-line training now will complete your training requirement for 2015. If you are seeking 2016 training you need to wait until next year.


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

The National Education Center for Agricultural Safety (NECAS) will host a webinar on Confined Manure Pit Safety on Friday Dec. 11 at 1 p.m. The live event will be available to anyone entering as a guest the day of the webinar (no preregistration needed). More information can be found here.

The Livestock and Poultry Environmental Learning Center will host a webinar on "Communicating Science Amidst Controversy" on Dec. 18th. For more information click here.

Dates have been announced for the 2016 Confinement Site Manure Applicator Workshop. A complete list of workshops can be found here.


Wishing you a happy Thanksgiving,
