pH Mapping and potash trials

To investigate the benefits of a range of spatial datasets including soil pH mapping, satellite imagery, yiled maps.To compare different potash rates in areas of paddocks which are believed to be potash deficient.本研究旨在探究一系列空间数据集（spatial datasets）的应用效益，涵盖土壤pH制图、卫星影像与产量分布图；同时在被认为存在钾素缺乏的农田地块中，对比不同钾肥施用量的应用效果。
