100+ tests - a great asset to great research


The Soil Testing Lab will be closed on Monday, May 27, 2024 in observance of Memorial Day.


Samples may be mailed/shipped to the lab or placed on the table outside the office in the hallway. We are not able to store and return cardboard boxes. Please use coolers or plastic tubs and totes.

If you have perishable samples or time-sensitive work that needs to be completed, email or call our office to arrange transfer ([email protected] / 612-625-3101). Email messages often result in fastest response.

COVID-19 Updates - masks recommended but not required.

Under penalty of law, soil from areas that are subject to domestic soil quarantines (see linked map) AND soils originating outside of the contiguous United States can only be submitted for testing by pre-arrangement in order to ensure compliance with APHIS regulations. Inquiries should be directed to [email protected].
