Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts

这项研究将通过改善目前营养失调和供水的诊断技术（树叶和土壤分析）来提高蓝桉种植园的生产力。使用一种新的韧皮部取样和分析技术，我们将开发一种快速，廉价，强大和可靠的现场使用的营养（如N，P）和水的诊断程序。一项重大的创新将是区分缺水对增长的影响和其他影响增长的因素。 总的来说，该项目将提供一个非常重要的理论，概念和实践的进步，中期轮换，诊断人工林具有相当大的商业前景。

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.
