You can take a soil sample to your local extension service office and, in most cases, they will perform a pH test for free. For best results, call the extension service office for instructions relative to how to take samples and how many to take. More comprehensive testing is usually available for a small fee by sending a sample to the university that sponsors the extension service in your state. The tests results will include a complete nutrient profile, NPK, etc. as well as physical characteristics of the soil (sandy, clay, loam, etc.)
