Macadamia nuts are an iconic native Australian product worth $287 million annually at the farm gate. Phosphorus fertiliser management currently threatens price premiums for sustainable production in high value European Union export markets, and ‘social license’ to farm in their densely populated coastal production areas. The project aims to exploit adaptive root and shoot traits for phosphorus efficiency found in Australian native plants to optimise phosphorus fertiliser management and set the platform for breeding macadamia root stocks/varieties that require less phosphorus fertiliser. The outcome will be a macadamia industry that is able to maintain current market price premiums and maintain social license to farm in coastal Australia.

澳洲坚果是澳大利亚标志性的本土产品，每年在农场门口价值2.87亿澳元。磷肥管理目前威胁到欧盟高价值出口市场可持续生产的价格溢价，以及在人口稠密的沿海生产区进行农业的“社会许可证”。该项目旨在利用澳大利亚本土植物中发现的适应性根和芽特性来提高磷效率，以优化磷肥管理，并为培育需要较少磷肥的澳洲坚果砧木/品种建立平台。其结果将是一个澳洲坚果产业，能够保持目前的市场价格溢价，并保持社会许可证，以农业在澳大利亚沿海地区。
