Rock Dusts

With the exception of nitrogen, all of the elements essential for higher plant growth are derived from rock and minerals. The fertility of your soil directly relates to the levels and range of these minerals found in our soils.

The addition of finely ground local rock dusts is a proven way to maximize this mineral content that is then further broken down by the microbiology in the soil, transforming it into a bio available form for our plants.
