Volcanic Rock Dust - 20kg
About this product
This finely ground volcanic dust has been found, in trials, to produce heavier crops with better flavour, higher nutritional content, longer storage life, better pest resistance and improved drought tolerance! Its extremely high mineral content actually improves the health of the soil, and it has also been found to speed up composting and produce better compost. Can be applied at any time of year. One 20kg bag is enough to treat 40m of soil.
