Soil Acidity and Alkalinity (pH)

A surface of predicted pH of layer 1 (A Horizon - top soil) surface for the intensive agricultural areas of Australia modelled from spot observations taken by soil agencies both State and CSIRO. The values have subsequently been rounded to the nearest whole number.本数据集呈现澳大利亚集约化农业区第一层土壤（A层——表层土壤）的预测pH值空间分布，其建模所用数据来源于各州土壤机构与澳大利亚联邦科学与工业研究组织（CSIRO）采集的土壤样点观测结果。所有后续数值均已修约至最接近的整数。
