A wide range of manure additives exist on the market. This fact sheet focuses on those products that can be added directly to the manure, or fed through the animal to impact manure.

This fact sheet is part of the Air Management Practices Assessment Tool (AMPAT) developed at Iowa State University and funded by the National Pork Board. Additional resources can be found on the AMPAT web site.
