Australian clays as raw materials of slow-release phosphate fertiliser

在澳大利亚，磷(P)肥料的投入是一个严重的问题，其效率低下的植物吸收，淋滤到自然水体和储存在土壤中的不溶性磷。该项目旨在利用澳大利亚原生粘土矿物开发活性粘土，以配制有效的缓释磷肥（SRF）和溶磷细菌的输送材料。这些组合物即使在环境波动的情况下也能可控地提供磷，但当植物生长时需要磷。开发多功能、无毒和植物生长驱动的磷肥将有利于以可持续的方式提高土壤肥力，在最大限度地提高磷肥投入效率的同时，将环境负担降至最低。

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.
