Phosphorus (P) fertiliser input in Australia is a significant problem for its inefficient plant uptake, leaching to natural water bodies and stocking of insoluble P in soil. The project aims to develop activated clays using Australian raw clay minerals to formulate effective slow-release phosphate (P) fertilisers (SRF) and delivery material for P-solubilising bacteria. Composite of these will supply P controllably even amid environmental fluctuations but when a plant needs as it grows. Development of multifunctional, nontoxic and plant growth-driven P fertiliser would benefit improve soil fertility in a sustainable way where efficiency of P input is maximised with a minimised environmental burden.

澳大利亚的磷肥投入是一个重要的问题，因为它的植物吸收效率低，淋溶到自然水体中，并在土壤中储存不溶性磷。该项目旨在利用澳大利亚原粘土矿物开发活性粘土，以配制有效的缓释磷酸盐（P）肥料（SRF）和溶磷细菌的输送材料。即使在环境波动的情况下，但当植物生长需要时，这些组合物也会可控地供应P。开发多功能、无毒和植物生长驱动型磷肥将有利于以可持续的方式提高土壤肥力，使磷投入效率最大化，环境负担最小化。
