Winter Manure Application. Here is a general reminder about winter application of manure in Iowa. The law is specific as to what types of livestock operations are affected by this law, but caution is urged to all when considering manure application in winter. It is not recommended and can pose a large risk of loss of nutrients to surface water. The law prohibits liquid manure application from confinement facilities (over 500 animal units) with liquid manure from Dec. 21 to April 1 if the ground is snow-covered. If manure can be properly injected or incorporated, it can be land applied during this time. Snow-covered ground is defined as soil having one inch or more of snow cover or one-half inch or more of ice cover. The law also limits manure application on frozen ground beginning February 1, annually. You can read more information about Iowa’s winter application law from DNR at:
Limits on Winter Manure Application for Confinements Start Late December.
Other things you need to consider if you are thinking about applying manure in the winter. First, if you have a NPDES permit, be sure to read the conditions of your permit. Generally speaking, winter application of manure is not allowed in a NPDES permit. Also, if you have a nutrient management plan or Comprehensive Nutrient Management Plan with USDA-NRCS please consult your plan or call NRCS to determine if winter application is allowed.
USDA-NRCS 590 Standard. The Iowa NRCS is in the process of making changes to the 590 Nutrient Management Standard. Public comment is open until February 6, 2013. Read the press release here or access the draft standard and a list of changes to the standard by visiting: http://www.ia.nrcs.usda.gov/technical/draftstandards.html.

This initiative is aimed at helping small feedlots and dairy operations (less than 1,000 animal units) better understand pollution potential of open feedlots. In the fall of 2012, Iowa State University Extension and Outreach in cooperation with initiative partners hosted a field day at the Bob Ziegmann farm near Wall Lake, Iowa. Manure Manager Magazine features this feedlot, the challenges faced, and the practices put in place and highlighted at the fall field day in their recent edition. You can access this success story on page14-17 in the January/February 2013 edition of Manure Manager.
Recently, two existing manure video segments produced by the Iowa Learning Farms with assistance from IMMAG, were translated into Spanish by the Livestock and Poultry Environmental Learning Center. Both videos focus on how to take manure samples.
