The purposes and methods of soil resistivity measurement were introduced in this paper. Particularly, the theoretical background, field operating steps and data processing method of soil resistivity measurement using specific earth resistance tester (Yokogawa Type3244 Japan) were explained with the example measurement in sandy woodland. The results showed that 'method using the 3244 specific earth resistance tester, based on Wenner principle, to measure the sandy woodland soil resistivity was feasible. The measured results of soil resistivity have a certain application prospect in sandy soil delamination, soil water content prediction and the underground water table determination.
