Diatomite Rock is a naturally mined mineral composed entirely of the skeletal remains of trillions of microscopic, unicellular plankton called diatoms. The porous aggregate particles wet rapidly and will absorb greater than 100% of their own weight in water, which they freely release to the surrounding soil and plant roots.
With an ideal pore size of 0.1 to 1.0 microns, Diatomite Rock acts as a water and nutrient reservoir for plant roots enabling them to withstand common environmental stresses, such as drought and temperature extremes, more easily. Indefinitely stable and non-compactable, Diatomite Rock permanently improves the structure, drainage and oxygen exchange of heavy soils and horticultural growing media.
- Derived from 100% diatomite
- Mix 10% by volume or about 1.5 lbs per gallon of soil
- For garden soils, apply 5 lbs per 10 sq ft.
