Phosphorus - A Key Factor in the Development of Novel Perennial Herbaceous Deep-rooted Pasture Legumes

这项研究旨在开发急需的多年生牧草豆科牧草，以扩大澳大利亚南部除紫花苜蓿外的多年生牧草选择。开发新的根深蒂固的多年生豆科牧草具有巨大的潜力，可以改善大片农田的养分和水分利用。在减少土壤侵蚀和酸化方面也可能带来好处。了解新的多年生豆科植物对土壤磷的反应是发展新的多年生耕作制度的先决条件。总体而言，从单个农民和农村工业到一般社区，环境和经济利益都将产生。

This research aims at the development of urgently needed perennial pasture legumes, to expand perennial pasture options for southern Australia beyond lucerne. The development of new deep-rooted perennial pasture legumes has enormous potential to improve nutrient and water use over large areas of agricultural land. Benefits in terms of reducing soil erosion and acidification are also likely. An understanding of the responses of new perennial legumes to soil phosphorus is a prerequisite for the development of new perennial farming systems. Overall, both environmental and financial benefits will accrue at scales ranging from individual farmers and rural industries through to the general community.
