Risk 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.

This advisory 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.

This map is most useful when used in conjunction with the Application Risk Management system. If the risk rating for your location allows manure application, follow up by filling out the ARM Worksheet to see if application for a specific field is okay. For more information, talk to your local nutrient management planner.
