This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.

这项研究将通过改进现有的诊断技术（叶片和土壤分析）来提高蓝胶种植园的生产力，用于营养失调和水的供应。利用一种新的韧皮部采样和分析技术，我们将开发一种快速、廉价、强大和可靠的营养（如氮、磷）和水分诊断程序，适用于田间使用。一项重大创新将是将水资源短缺对增长的影响与其他增长影响区分开来。总体而言，该项目将在中期轮作诊断方面提供非常重要的理论、概念和实践进展，具有相当大的商业前景。
