The nature and ecological functions of soil soluble organic nitrogen in contrasting forest ecosystems

该项目采用了一系列创新技术来研究土壤可溶性有机氮的动态性质和生态意义--土壤可溶性有机氮是热带、亚热带和温带森林生态系统中重要的营养库之一。该项目的成功实施将导致：(A)更好的施肥建议方案，减少生态系统氮的损失，提高森林生产力和可持续性，最大限度地减少环境污染，改善森林流域的水质；(B)有效保护管理森林和天然森林的生物多样性；以及(C)加强澳大利亚科学家在相关研究领域的国际合作和声誉。

This project employs a series of innovative techniques to investigate the dynamic nature and ecological significance of soil soluble organic nitrogen - one of the important nutrient pools, in contrasting tropical, subtropical and temperate forest ecosystems. The successful conduct of this project will lead to: a) better fertilization recommendation schemes, reduced ecosystem N losses, improved forest productivity and sustainability, minimised environmental pollution and improved water quality in forested watersheds; b) effective conservation of biodiversity in both managed and natural forests; and c) enhanced international cooperation and reputation of the Australian scientists in the relevant research fields.
