Notes on Manure Spreading Advisory (MSA) Map
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.
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.
