Mined from a rare deposit of silicon rich, non-crystalline volcanic tuff formed over 30 million years ago by a pyroclastic flow.
Has a rich amorphous content that contains over 76% SiO2 providing a natural source of plant available silicon (silicic acid).
Porosity Unlike Any Other Silicon Source
Extremely porous, weathers easily, and provides immediate and gradual release of plant available silicon.
Reacts dynamically with other minerals and nutrients to address critical soil and plant deficiencies.
Amorphous, non-crystalline silicon and is not a hazardous or harmful material. Click below for safety data sheet.
