response: Hello Gregory, I am sorry your question has taken so long to be answered! The original person your question was assigned to was out of the office. I can help you with the soil testing process. If you stop by your county's Cooperative Extension Office, we can give you a bag to collect soil in. If you would prefer, you can bring about a quart of soil into the office and we can transfer it from a plastic bag to the soil sample bag. Here is a link with the websites and addresses for all of the Kentucky Cooperative Extension Offices. https://extension.ca.uky.edu/county The soil that you collect should be taken from multiple locations around the area that you would like information on. If you are taking it from an untilled location such as a lawn, take the soil up to a depth of four inches. If you are taking the sample from a location that you frequently dig or till, you should take the soil from a depth of up to 6 inches. You can bring multiple different soil samples. I generally taking a sample each from your front yard, back yard, flower garden, and vegetable garden. Once we get it from you, we will send it away to our laboratory in Lexington. They will then test it and we will will send you a report with its pH and nutrient content, as well as recommendations on any amendments you may need for the plant that you tell us you're going to grow/are growing. This test will not give information on possible compaction, which sounds like it could be an issue in your circumstance.  Let me know if you have any questions! Robby
