How is manure changing over time? Trends in Midwest manure sample data

This post comes from our colleagues at the University of Minnesota -College of Extension. Follow their latest news on their blog: Minnesota Crop News

This post was written by: Nancy Bohl Bormann, Graduate research assistant; Melissa Wilson, Extension manure management specialist, & Erin Cortus, Extension engineer

Key Points

  • Current livestock manure “book values” (the approximate amounts of various nutrients in manure) are several decades old.
  • Using recent data from several Midwest U.S. labs, we found that manure nutrient data have changed over time compared to previous Midwest Plan Service (MWPS) manure book values.
  • The University of Minnesota is creating a manure nutrient database called ManureDB to help update these values.
  • We are currently looking to partner with laboratories that analyze manure on this project.
