Volcanic Rock Dust

Volcanic Rock Dust is an organic fertilizer consisting of crushed basalt, a volcanic rock, which contains minerals and trace elements which have been ground into a fine dust. Volcanic Rock Dust can be added to the soil to improve fertility, providing calcium, iron, magnesium, phosphorus, and potassium, plus over 70 minerals, trace elements and micronutrients. Gardeners have described this as 'magical'. Volcanic Rock Dust mimics the slow process of the earth's own ecosystem to replenish soils and restore the biosphere. When adding rock dust to the soil it allows for a lot more phosphorus uptake and thus largely reduces the amount of phosphorous fertilizers needed.
