About Glacial Rock Dust ....

Glacial Rock Dust is a natural mineral product, which is produced over many thousands of years by glacial action. As the glacier recedes, it leaves behind deposits of "glacial moraine". These deposits are mined, dried and screened for agricultural and horticultural re-mineralization. Glacial Rock Dust can replace key elements that have been depleted from the soil over the years in a form readily used by soil microbes to create healthy soil. Glacial Rock Dust lets the soil re-create the colloids (minerals and humus) which are needed to improve soil structure, moisture holding properties, nutrient availability and bacterial action. When the correct balance is achieved, organic matter is turned into humus and the soil becomes a favorable environment for a host of beneficial molds, fungi, bacteria and earthworms.

Glacial Rock Dust can increase phosphorous availability, provide an excellent source of calcium, iron, magnesium and potassium and supply trace elements and micronutrients including free silica. It can also increase moisture-holding properties in the soil, improve the cation exchange capacity and improve soil structure and drainage. You cannot over apply Glacial Rock Dust! It will not burn!
