With climate change, Australian agriculture is faced with periods of increasing drought and changing rainfall patterns. At the same time, Australian farmers are faced with increasing costs of fertiliser inputs (their largest variable input cost), yet have little information on how they should change their nutrient management programs to suit the changing climatic conditions. This project aims to determine the effect of drought and rainfall patterns on the efficiency of fertiliser use by crops, through examination of the effects of soil moisture conditions on the interaction between soil and added fertilisers.

随着气候变化，澳大利亚农业面临着干旱加剧和降雨模式变化的时期。与此同时，澳大利亚农民面临着肥料投入成本的增加（他们最大的可变投入成本），但他们对如何改变营养管理计划以适应不断变化的气候条件知之甚少。该项目旨在通过检查土壤湿度条件对土壤和添加肥料之间相互作用的影响，确定干旱和降雨模式对作物使用肥料效率的影响。
