BIO-ACTIVATED GRANULAR SOFT ROCK PHOSPHATE
Superior Fertilisers bio-activated Soft Rock Phosphate is more than just superphosphate.
26 different types of microbes are granulated into the product to allow for fast release of the phosphorus and other nutrients in our product.
Mycorrhiza fungi, Rhizobium and Bacilli (Bacillus megaterium) are the main movers and shakers involved in the release of phosphorous from our product and re-activation of accumulated soil phosphorus.
Accompanying the 11.2% P present in our product are extra valuable nutrients like Calcium, Sulphur, Silicon and useful quantities of essential trace nutrients like Copper, Zinc and Boron.
Granular Soft Rock Phosphate and our custom blends have been used in the 2014-2015 cane season in the Mackay region by Marian grower and Nuffield Scholar Simon Mattsson.
Superior Fertiliser products offer an immediate supply of nutrients for the young crop to utilise, as well as, slow release over the full duration of the crop cycle.
Reduced leaching of nutrient from mineral fertilisers into the ground and ultimately surface water streams lowers the nutrient load running into the Great Barrier Reef.
Simon’s preliminary cane yields and PRS harvested from his strip trial in July 2015 show...
