The Whitetail Institute DVD emphasizes soil testing, and it is right on the money. I have tested and limed my soil and planted Imperial Whitetail Clover, Chicory Plus and Chic Magnet. The information in the video is something that along with the Whitetail Institute products will result in larger, healthier and more plentiful deer. I have seen it on my property, with a 136-5/8- inch 8-pointer killed.
