Restore Minerals to your Garden Soil Using Rock Dust
Rock dust is an environmentally-friendly soil additive that restores a high level of minerals and trace elements to your soil in balanced quantities.
Rock dust is water soluble, easy to apply and restores nutrients to the soil that have been lost by erosion, overworking the soil and leaching.
Please note that rock dust is NOT a fertilizer and will not replace the need for fertilizers containing nitrogen, phosphorus and potassium. It DOES replace over 60 trace elements and micronutrients not typically found in most commercially available fertilizers and it does so organically.
