FYTO Cal is a very efficient high concentration Calcium and Boron product, which with dissolving in water before application will result in total chelation of the Ca 2+ to the natural organic fulvic acid molecules of the Fytofulvic powder. In the chelated form, chemical reaction between the Ca2+ cation and PO4 2- anion will be limited which keeps both nutrient elements in a soluble and available form that the crop can take up and ensure optimal utilization of both elements.
