Winter Manure Applications and Restrictions

Jon Schmitz, Agronomy Sales Manager (507) 434-0016
2018 has proven itself to be a challenging year, and the challenges continue into this late fall harvest. As harvest gets delayed so does some of the other critical field work that must be completed, not the least of which is manure applications for
our livestock producers.

History shows that if there is going to be an environmental issue regarding manure applications the highest percentage of occurrences occur during winter applications on frozen and snow covered ground. Taking some extra precautions now can help minimize potential problems in the future.

I know the fall so far has been particularly challenging when it comes to applying manure, particularly liquid manure that needs to be incorporated for the larger NPDES permitted sites. The plan that you had set in place may have gone out the door with fall.

Most of you know the restrictions for applying manure within sensitive features, but as we move into a critical time for manure applications I thought this would be a good time to recap what those restrictions are. There is a visual map of the required setbacks as well
as a table indicating what those setbacks are depending on whether the manure is incorporated or not. Please take the time to review these documents. If you are a federally permitted facility there are some additional requirements that you need to follow in regard to manure applications on frozen and snow covered ground. Your permit will outline those requirements for both liquid and dry manure.

Abiding by these setback requirements can save a lot of headache in the future, and can ensure continued water quality improvement in SE. Minnesota.

If you have questions regarding these setbacks or would like more detailed information about applying manure in sensitive features please feel free to contact me at 507-434-0016.
