A new row starter and y-drop formulation to capitalize on a low salt formulation to supply your corn crops macro nutrient needs. Unlike a UAN, 10-34-0, or Thiosul blend, 15-15-3-3S is a 100% ammonium nitrogen and 50% orthophosphate product. This means more nutrients into the plant for better nutrient use efficiency. 15-15-3-3S can be blended 1:1 with UAN or used by itself. Because of its unique formulation, this product blends easily with micronutrients and organic acids.
