Measuring Soil Electrical Resistivity Using a Resistivity Box and a Resistivity Probe
This technical note deals with the fabrication and details of an electrical resistivity box and an electrical resistivity probe, for estimating soil electrical resistivity. Calibration of these setups has been done with the standard KCl and NaCl solutions. Using this calibration, electrical resistivity of a locally available silty soil and commercially available white clay has been determined. Further, efforts have been made to develop relationships between the electrical resistivity of these soils and their saturation. Results available in the literature have been used to validate these relationships.
