This project aims to reduce reliance on nitrogen fertilisers without reducing crop yield. Global food security relies on using high-yielding grain varieties and nitrogen-based fertilisers. Since 1950, fertiliser use has increased 20-fold but the yield benefits of this use are declining. Crops only absorb 30–50 per cent of the applied fertiliser and the unused nitrogen causes environmental damage which is costly to mitigate. The novel technology platform of the project aims to develop new crops with more expansive root systems that use applied nitrogen fertiliser more efficiently and new legume varieties that symbiotically fix more nitrogen in an ecologically-sustainable way.

该项目旨在减少对氮肥的依赖而不降低作物产量。全球粮食安全依赖于使用高产谷物品种和氮基肥料。自 1950 年以来，化肥使用量增加了 20 倍，但其产量效益却在下降。农作物仅吸收所施肥料的 30-50%，而未使用的氮会造成环境破坏，而减轻这种影响的成本高昂。该项目的新颖技术平台旨在开发具有更广泛的根系的新作物，更有效地利用所施用的氮肥，以及以生态可持续的方式共生固定更多氮的豆科新品种。
