About Glacial Rock Dust

Glacial Rock Dust is made from a wide variety of rocks which contain a broad spectrum of trace minerals that are collected and pulverized by the expansion and contraction of glaciers. As the glacier recedes, it leaves behind deposits of glacial moraine. These jumbled piles of debris are processed into dusts. Nature has already done the work of mixing and much of the grinding.

Glacial Rock Dust is an excellent source of readily available calcium, iron, magnesium and potassium plus trace elements and micronutrients. It also increases phosphorus availability to plants.
