Rock mineral fertilisers are derived from natural volcanic and sedimentary deposits containing some of nature?s richest soil building materials. These fertilisers contain excellent complements of micro-elements, beneficial soil microbes, and are naturally slow release and non leaching. These intelligent fertilisers use microbes to gradually make the minerals available to plants.
