A tool from theUniversity of Minnesota allows you to put some numbers to how much aroma originates from your dairy — from either existing facilities or proposed expansions . In addition you can use the tool to help you determine how far away you need to keep animal facilities or manure storage from neighbors to reduce annoying odor conditions that occur sometimes.

Although designed for use in Minnesota, the Odor From Feedlots Setback Estimation Tool, or OFFSET, has been successfully used in other states. Just be sure to change the weather data to reflect your local conditions.
