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

本研究旨在开发急需的多年生牧草豆科植物，以扩大澳大利亚南部多年生牧草的选择范围，超越卢塞恩。开发新的深根多年生牧草豆类具有巨大的潜力，可以改善大面积农业用地的养分和水分利用。在减少土壤侵蚀和酸化方面也可能产生效益。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农业系统的先决条件。总的来说，环境和财政利益将在从农民个人和农村工业到整个社区的规模上积累。

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.
