Alfa-Rack Plus has all the same features and benefits you have grown to expect and rely on with the original Alfa-Rack product. Alfa-Rack Plus, however, has two factors that make it perform even better than the original. First we have incorporated X-9 Alfalfa Technology which is derived from using the newest grazing varieties available. X-9 Alfalfa Technology enables Alfalfa Rack Plus to be more attractive and have a greater yield than traditional alfalfa varieties as well as many other advantages. Second, we have added chicory to the blend, which is highly drought tolerant and attractive to deer especially in late summer and fall. Like the original Alfa-Rack, Alfa-Rack Plus also contains Imperial Whitetail Clover. Alfa-Rack Plus is more palatable to deer, has greater yield, more cold heat tolerable, more drought resistant, and is longer lasting up to 5 years. 13.5 lbs. per acre.
