Hi, 

We would recommend that you use a soil analysis laboratory over a home test kit for a more accurate reading. You can review our soil testing information page for guidance. There is a list of laboratories you can choose from. Their associated websites will give you directions on how to submit a sample. We also have a helpful video on how to do so and how to read the test results afterwards.

Let us know if you need further assistance or would like help interpreting the results when you receive them.
