hello Custom Cuts
You will be calling Dr. Mary Grodner's office. The telephone # is 225-318-2364, for test booklets. Tell them where you live and they will tell you where to call to set up time and place for test.
If you let them know what tests you want to take they will send you the correct booklets. The last ones I got were $5 each. They will also let you know how much the tests are to take. If you are doing turf and ornamental, my advice is really study the thin booklet, it almost caught me.
