You can submit soil samples to the lab in one of two ways:
- Obtain the soil sample boxes, instructions and forms from the Hamilton County Extension Office, either in person or by mail (call 423-855-6113) OR
- Access and download the instructions and forms from the Soil, Plant and Pest Center website and collect your sample(s) in quart-size zip lock bag(s).
Either way, you then mail the sample(s), completed form(s) and payment (if paying by check) together in one package to:
UTIA Soil, Plant and Pest Center
5201 Marchant Dr.
Nashville, TN 37211
Once you receive the results back from the lab (usually within two weeks), if you have any questions about the report or need any further advice or information, please contact the Hamilton County Extension Office at (423) 855-6113.
