How to Submit Samples for Analysis

  1. Download, print and fill out the Lawn & Garden Soil Analysis Request Sheet. Use one sheet per sample. For faster turnaround, include your email address and we will email you the results.

  2. Follow the instructions for collecting samples on the second/back page of the PDF and watch the How to Take a Soil Sample video.

  3. The sample size should be about 2-3 cups.

  4. Place the sample in a secure container such as a clean plastic tub or sealable plastic bag. Label the container with a sample name or number that matches what you put on the request sheet.

  5. Enclose a check payable to the University of Minnesota for all services requested. Do NOT send cash - we cannot be responsible for cash sent through the mail. You may also pay with a credit card. Scroll down for prices.
