Field Soil
Electrical Resistivity
Four metal electrodes are placed with equal separation in a straight line in the surface of soil to a depth not exceeding 5% of the minimum separation of the electrodes. A voltage is impressed between the outer electrodes causing current to flow and the voltage drop between the inner electrodes is measured using a sensitive voltmeter. The resulting resistivity measurement represents the average resistivity of a hemisphere of soil of a radius equal to the electrode separation.
