GroMax Microbe and Rock Mineral Fertilisers differ from conventional fertilisers as they offer an environmentally friendly way to feed your plants and assist in building healthy soils. Our 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 releasing and non-leaching. These intelligent fertilisers use microbes to gradually make the minerals available to plants.
