If you do not have an independent testing laboratory nearby, then look under your county government offices in your local telephone book to see if your area is served by an Agricultural Extension Service Office of your home state's land grant university.  If you are unable to find a telephone number for your extension office, call your closest state land-grant school direct, ask for the person in charge of "Extension  Services" or someone in the University's college of agriculture--usually in the Department of Agronomy.
