Glacial Rock Dust can replace key elements that have been depleted from the soil over the years, replacing these missing minerals in a form readily used by soil microbes to create healthy soil.
Our 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. When this happens, the living soil becomes a buffer to the many variables gardeners must contend with.
Glacial Rock Dust is high in natural silica and provides an excellent source of calcium, iron, magnesium and potassium, and trace elements and micronutrients. It can also increase moisture-holding properties in the soil, improve the cation exchange capacity, and improve soil structure and drainage.
