Thank you for your inquiry about soil tests. You can purchase soil sample bags through Michigan State University Extension and receive recommendations directly from MSU. A&L Labs analyze the soil samples and send results to MSU Extension where a recommendation will be generated and sent to you by expert MSU Extension staff. All MSU recommendations utilize the latest research and follow state laws and guidelines.

Home Lawn and Garden soil self-mailers including sample bags are available for purchase through local MSU Extension offices (https://www.canr.msu.edu/outreach/county) or even easier through the MSU Bookstore at https://shop.msu.edu/products/soil-test-mailer
where they are mailed directly to you. The Oakland County office(s) should have some in stock, but I would recommend calling beforehand to make sure.

Commercial soil sample bags can only be purchased in person at MSU Extension offices. The cost for the commercial samples does not include shipping costs to A&L Labs.

Please note it is important clients purchase the correct sample bag (Home Lawn and Garden vs. Commercial). There are different recommendations for commercial and home lawn and garden samples. Commercial tests give result in tons per acre, which will not be helpful for residential purposes.

Also, the soil tests do not test for heavy metals, pesticide residue on soil and plants, or PFOS. For a list of labs that provide those types of tests, visit https://www.canr.msu.edu/news/testing-for-contaminants-in-soil-water-and-plants

Toll Free Number:<personal data hidden> – for questions related to MSU Extension Soil Test results. This number is also found on the soil test forms and included in results for commercial clients.

Thank you for reaching out. Best wishes this growing season!
