OSAMIN200 is a liquid plant-available O-Silicic acid with High Silica Content (2%) with long shelf life and immediate results. Plants can absorb silicon only in the form of Orthosilicic acid (OSA). OSA is water soluble and is the only biologically active form of silica. OSAMIN200 is taken up by the plants in very low concentrations but that concentrations have a very important effect on plant growth.
