Silica Rich Clay


The formation of this unique clay began millions of years ago as a result of underground molten lava activity near what is known today as Crater Lake, Oregon. During the last Ice Age, slow moving glaciers removed the protective earthen cap from this deposit, exposing this extraordinary gift from the earth.

Ingredients: An analysis of Silica Rich Clay reveals its exceptionally rich silica content - approximately 60% ) - along with well over 65 other trace minerals. Silicic acids, a natural byproduct of mineral silica, microbes and moisture, are required by plants in order to convert other minerals and soil nutrients into bioavailable forms. This may explain why plants grow stronger, are more disease resistant, produce larger crop yields with higher nutrient and sugar content. It may also explain why bound up phosphates in the soil are released in plant available forms, thereby reducing toxic runoff problems in our streams and lakes. The rich alumino-silicate properties of this clay may explain why unhealthy fungal and bacterial growth diminish while beneficial soil micro-organisms and mycorrhizae increase in the soil.

Recommended Use:

Surface Application:
Per Square Foot: Spread 1-2 tablespoons of Silica Rich-Coarse Grind per square foot to the surface soil. Simply leave on the surface and water in, or mix thoroughly into the soil.

Per Acre: Based on current soil quality and degree of chemical pollutants in the soil, apply 500 to 2,000 lb per acre the first year, applied all at once or in increments over time. Then apply 200 lb per acre each year thereafter. Anticipate a steady improvement each year in soil quality, plant health, and crop yields.
