Silicate minerals (including Silicon) is a major constituent of the Earth’s crust, and most soils commonly contain about 30% Si by weight.Early researchers regarded Silicon (Si) as nonessential to plant vigor. More recent research on the mechanisms of Si uptake, transport, and accumulation in plants indicate the Silicon is more essential than initially thought. 

Silica is a compound containing both the element Silicon (Si) and Oxygen (O), known to scientists as silicon dioxide [SiO2]. Silicic acid [Si(OH)4] or Monosilicic acid [H4SiO4] refer to the soluble, plant-available forms of Silica. Silicic acid, a fundamental building block of all silicas, is the simplest form of silica. 

Amorphous silica may have an ability to detoxify with its large surface area, which acts like a sponge and magnet to attract and chelate toxic compounds. It has been shown to detoxify soils from certain heavy metals.

Recognizing the indicated benefits of silicic acid, agronomists and soil scientists gathered for the Tri-Societies Conference in Ohio in 2013, which brought together representatives from the American Society of Agronomy (ASA), the Crop Science Society of America (CSSA), and the Soil Science Society of America (SSSA).  Researchers at the conference concluded that trial data and anecdotal evidence has shown that supplemental soil products with silicic acid – like Silica Earth™
