Accessing WI 590 Nutrient and Manure Application Restriction Maps on the Web

On-farm nutrient management begins with a good understanding of field-specific soils and their ability to accept nutrients and manure for optimal crop production while protecting water quality. Nutrient and Manure Application Restriction Maps show where, when, and how much manure can be applied within Wisconsin state rules (2005 Wisconsin NRCS 590 Nutrient Management Practice Standard).

These maps are available for free on-line for the entire state for use by planners, producers, and manure applicators. You can directly access the page and download maps by going to the Help menu and selecting 590 Restriction Maps or you can connect to the website via http://www.manureadvisorysystem.wi.gov.

SnapPlus Version 1 users accessed the "590 Nutrient Application Restriction Maps" link to download GeoPDF® files; these files are no longer available.

The 590 Nutrient Management Practice restriction areas identified on the maps are: 

•Soil mapping units with slope restrictions; C slopes are labeled as Winter Restrictions (if slope > 9%); D+ slopes are labeled as No Winter Application (slope > 12%)

•Soil mapping units with nitrogen application restrictions (labeled as Fall N Restrictions)

•Surface Water Quality Management Areas (300 ft from perennial streams, 1000 ft from lakes/ponds) are labeled as SWQMA (No Winter Application, Other Non-Winter Restrictions)

•CAFO plans under NR243 can use CAFO-specific Surface Water Quality Management Areas and Fall N Restrictions
