Gaia Green Glacial Rock Dust
Both plants and animals, including humans, benefit from a regular supply of trace minerals, which are best transferred to the human body through vegetables grown in soil rich in trace minerals.Glacial Rock Dust is a natural mineral product which is produced over many thousands of years by glacial action.  A wide variety of rocks which contain a broad spectrum of trace minerals 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.Today nearly all agricultural land is depleted of trace minerals, due in part to the exclusive use of chemical fertilizers and ground water pollution.  For trace minerals to be quickly absorbed by plants , they must first be finely ground into rock dust.  In technical terms - 74 microns.  Because these trace minerals are so finely ground, they react like clay, clumping together when any amount of moisture is added.It is not necessary to add or replace trace minerals, for they are slowly released in the soil over many years.
