Current Manure Setback:

= 80 ft minimum

October through February
**Big gun application should never be closer than 40ft due to drift

The following ARM Worksheet should be used in conjunction with your Nutrient Management Plan and application guidance to help you determine when applying manure is advisable.

To access the ARM Worksheet follow the steps below.

6 Steps for Application Risk Management
  1. Evaluate your fields

  2. Check the forecast by clicking your location on the ARM Weather Map below
    (Click HERE for MOBILE version if the map below does not load for you)

  3. Fill out the ARM Worksheet by clicking the ARM Worksheet link in the map pop-up and find out your application risk rating.
    You can link directly to the worksheet HERE or access it through the map to auto-fill precipitation data. 

  4. Print and save your worksheet for your records. If the risk is high, don't apply!

The risk value on the map is based on the 72 hour precipitation forecast for a given area. This value best predicts the potential risk associated with movement of manure applied to a field.

Notes on the ARM Weather Map

This ARM Weather Map is the first step in assessing if your field conditions are suitable for manure application and should be followed up with observation of your field characteristics to determine if manure application is appropriate at any time of the year. In some cases, even when the advisory is med-high, you may have individual fields that can be applied to because they are low risk. The ARM worksheet will help you take the next step to assess the risk associated with application to individual fields.


Disclaimer

Please note, even if this map says your risk is low, it cannot account for every variable or condition present on your field. It is your responsibility to use your best judgment and adhere to all application guidelines outlined in your plan. Always err on the side of caution to prevent unwanted discharges. Manure application practices that cause a discharge can lead to fines and/or necessitate a CAFO permit for your facility. The Whatcom Conservation District and the NRCS assume no responsibility for inappropriate manure application. Proper application is ultimately your responsibility.

We got the idea on how to present the information from the Wisconsin Manure Management Advisory System.  Thanks to Rick Wayne, UW-Madison, Dept. of Soil Sciences for helping on this project!

Thanks to Greg Corradini for a lot of the help getting this code together.  Without him there wouldn't be a site!

Of course we wouldn't have much of a site without the data we retrieve from the NOAA prediction website.
