Role of Silicon in Plant Culture | PRO-MIX Greenhouse Growing

Silicon is the second most abundant element in the earth's crust and is found in significant quantities in the soil; however, silicon can only be taken up by the plant in the form of mono-silicic acid. Most dicots (broad leaf plants) take up small quantities of silicon and accumulate less than 0.5% in their tissue.
