Tests and fees

Tests and fees for the following sample types can be found below:

Method of payment

  • We only accept checks as payment for samples submitted directly to the lab. Samples should be accompanied by a completed sample information form and a check for the amount due payable to MU Soil Testing.
  • The lab also accepts purchase orders. Contact the lab to discuss this process.
  • If you have an account set up with the lab, include the firm and outlet number and we will bill you at the end of the month.
  • Do not send cash with samples.
