2019 Certified Manure Testing Laboratories

Manure analysis is strongly recommended to help farmers know the value of manure applied to their crops in place of commercial fertilizer. Using manure in place of commercial fertilizer often results in increased crop yields, but accurate analysis of the manure is crucial.

The following laboratories, arranged by state or province, are certified by the Minnesota Department of Agriculture for manure testing. To find out more information about the laboratory, including the types of tests it is certified to run, click on the laboratory's name.

This is the only manure analysis certification of laboratories in North America. All of the laboratories have been certified for Total Nitrogen and Total Phosphorus. Many laboratories also elected to become certified for other tests including: Total Potassium, Total Solids, Electrical Conductivity, Copper, Sulfur, and Zinc. Make sure the laboratory you use is certified for the tests that are important to your farming operation.

Before submitting samples, please contact the laboratory for instructions. Many laboratories provide sample containers.
