Australia-based company Minbos Resources has lodged an Australian provisional patent application for a new phosphate rock fertilizer blend, with the potential to produce a 100% organic phosphate fertilizer using less reactive phosphate rocks.
New patent application has been filed to cover the new phosphate rock fertilizer blend following analysis of results comparing different product forms of the Cabinda Phosphate Granules in field trials in Angola and greenhouse trials at the International Fertilizer Development Centre (IFDC) in the US, and a survey of literature.
According to Minbos, the new phosphate rock fertilizer blend promotes the early release of phosphate nutrients from phosphate rock, potentially eliminating monoammonium phosphate (MAP) from the proposed Cabinda Phosphate granule formulation – delivering a 100% organic fertilizer blend.
