Centre Pivot Irrigation report, executive summary

An objective of this research was to create a water balance model for white clover seed production. In conjunction with the water balance investigation, determination of $return/ML applied to assess water use efficiency would be studied. Overlaying this research was the aim of assessing current, as well as historical, impacts of irrigation management on soil chemistry and structure. The objectivewas to gain more understanding of how irrigation practices affect the soil and how this in turn impacts on white clover production both presently and into the future本研究的目标之一是构建适用于白三叶种子生产的水分平衡模型。结合本次水分平衡研究，本研究还将开展每兆升（ML）灌溉投入收益的测定工作，以评估水分利用效率。与此同时，本研究的另一核心目标是评估灌溉管理对土壤化学性质与结构的当前及历史影响。本研究旨在进一步明晰灌溉措施如何作用于土壤，并进而如何影响当前及未来的白三叶种子生产。
