SIGNATURE® SST 8% CALCIUM is a highly advanced form of calcium designed for enhanced foliar uptake. This unique form of calcium has a lower pH and higher foliar availability than traditional forms of calcium. The addition of the proprietary SST silica (Stabilized Silica Technology) provides 2% silica for enhanced physical toughness and resistance to environmental stress as well as enhanced tank mix compatibility. SST Silica: Silica, found naturally in soils although widely abundant, is only slowly and sparingly available to plants. Because of a proprietary manufacturing process, SST silica is stable at pH ranges down to 3, unlike other silica products that are only stable to a pH of 9 or higher. SST also has a smaller particle size for enhanced plant availability. When SST silica is applied, the silica is absorbed and stored internally in plant tissues, increasing the physical strength and rigidity of the leaf tissues. This results in enhanced resistance to damage and stress conditions.
