Enhancing phosphorus use efficiency in macadamia for sustainable production

澳洲坚果是一种标志性的澳大利亚本土产品，每年在农场门口的价值为2.87亿美元。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，以及在人口密集的沿海生产地区耕种的“社会许可证”。该项目旨在利用澳大利亚本土植物的适应性根和梢性状，以优化磷肥管理，并为培育需要较少磷肥的澳洲坚果砧木/品种搭建平台。结果将是，澳洲坚果产业能够维持目前的市场溢价，并保持在澳大利亚沿海地区种植的社会许可证。

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.
