In a nutshell....
Rock dust is an eco friendly soil improver made from crushed volcanic rocks. Recommended by Charles Dowding for use in a no dig garden.
Over cultivated and continually cropped soils can be low in essential minerals and rock dust is mineral rich ground basalt (volcanic rock) which replaces the lost minerals in your soil. Even a light dusting can make a difference, especially if plants are growing less well then you think they should. Sprinkle a 1-5mm layer on your beds at any time of the year.
I am finding it helpful to container-grown plants as well, either a 1cm layer added to their surface, or the dust mixed into compost before filling pots; trials are ongoing as I write! A 1.5cm (half inch) surface layer on container compost makes an excellent weed suppressing mulch. - CD
Rockdust is ground volcanic rock, packed full of nutrients that are very beneficial to soil. Also called a soil amendment or soil additive, it is a completely safe to use, non toxic, environmentally friendly, chemical free soil remineraliser. It re adds vital minerals back into tired soil and increases long term sustainable fertility. Rockdust is ground very finely to allow it to be absorbed into the soil quicker and more efficiently. Adding it to your soil produces the very best vegetable growing soil.
Rockdust contains the following micronutrients/trace minerals:
Boron, Calcium, Cobalt, Chromium, Copper, Iron, Potassium, Magnesium, Manganese, Molybdenum, Sodium, Sulphur and Zinc.
