Nature's Footprint Glacial Rock Dust Soil amendment, 25-Pound
Glacial Rock Dust is a soil amendment containing a broad range of trace minerals, many of which have been slowly lost through the ages on commercial farmland, by erosion, leaching and farming practices. Plants and animals benefit from a regular supply of trace minerals, which are best transferred to the human body through foods grown in soil rich in trace minerals.  Glacial Rock Dust can be used in vegetable gardens, flower gardens, on lawns, and around trees. Minerals contained in Glacial Rock Dust are an essential part of the soil food web. Glacial Rock Dust should be applied during the spring once per year, but can be applied seasonally for intensive growing.
