Attention International Buyers: Please contact me for correct shipping chargesWhy Glacial Rock Dust?Glacial Rock Dust contains 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. Glacial Rock Dust is a natural mineral product which is produced over many thousands of years by glacial action.Both plants and animals, including humans, benefit from a regular supply of the trace minerals present in Glacial Rock Dust, which are best transferred to the human body through foods grown in soil rich in trace minerals.Glacial Rock Dust is organic and loaded with essential nutrients that it releases slowly so your plants can be healthy throughout the growing season. It will encourage the root systems of trees, lawns, roses, and vegetable gardens. Add as a soil amendment to your garden, raised beds, or container garden to improve the quality of your soil and add essential minerals to your harvested fruits and vegetables.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/contraction action of the glacier. As the glacier recedes, it leaves behind deposits of "glacial moraine". These deposits are mined, dried, and screened for agricultural and horticultural re‐mineralization.Benefits of Glacial Rock DustGlacial Rock Dust isn’t just for vegetable gardens. It can also be used in flower beds for increased number of blooms, larger blooms, and healthier growth. Glacial Rock Dust will improve root structures of trees and lawns as well. Vegetables will have fewer pests and increased yields. The mineral nutrients in Glacial Rock Dust work with the soil rather than against it like chemical fertilizers, building healthy soil full of plant‐available nutrients and life. Glacial Rock Dust should be applied during the spring once per year, but can be applied seasonally for intensive growing.Glacial Rock Dust is an excellent source of readily available calcium, iron, magnesium and potassium plus trace elements and micronutrients. It also increases phosphorous availability to plants.Glacial Rock Dust improves 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 negative variables gardeners must contend with. Minerals contained in Glacial Rock Dust are an essential part of the soil food web.How to use Glacial Rock DustTransplanting and pre‐mixing soil for potted plants: 8 tablespoons into 1 gallon of soil or growing medium.Top dressing potted plants: 4 tablespoons per 1 gallon of soil or growing medium.
