Soil testing? #922031

Asked November 16, 2025, 4:44 PM EST

Hello, I'm trying to figure out where/with whom I can test my soil. I see a lot of resources but having trouble figuring out who will actually test my soil!

Thanks for your question, Ann.  The list is pretty short, and it depends what you want to test for.  Note that none of the Extension offices in the Metro area do this testing.  There are simple tests you can buy in garden shops, but only rough estimates of accurate soil pH and nutrient values.  Here's more about testing itself:

I hope this information is helpful.  Good luck!
