where can I send soil samples to be tested in Illinois?

Answer 1

Your county agricultural agent is the place to take soil samples for testing if you need to know the composition of your soil for agricultural purposes. For other types of testing such as environmental or water purity issues, here is a link to an Illinois company that specialized in that kind of testing:
