Innerzim Boost (Calcium) is a patented amino acid chelated calcium specifically designed for foliar application. The advantage of using Innerzim Boost (Calcium) is that the amino acids surround and protect the calcium from adverse interactions. Because it uses natural amino acids to chelate the Calcium, Innerzim Boost (Calcium) is rapidly absorbed, translocated, and metabolized by plants. Solubility in water is essential for absorption by plants. This is true of systemic chemicals as well as nutrients. The material must be soluble to pass through the surface and into the cells of the plant. Insoluble mineral salts, all oxides, most hydroxides, carbonates and phosphates, and some sulfates cannot be efficiently absorbed by the plant. When foliar application of these forms of minerals is made, they simply coat the external surface of the plant with the unavailable mineral. Innerzim Boost (Calcium) is completely soluble in water and consequently available for absorption by the plant. Innerzim Boost (Calcium) can be used on a variety of fruit, vegetable and other crops at the right stage and the right time.
