WebSoil Resistivity Measurement Techniques. Soil electrical resistivity measurement might be carried out using different methods such as geological maps, seismic testing and ground penetrating radar. In these methods, the soil resistivity estimation is mainly based either on (i) electrodes spacing, or (ii) satellite imaging techniques [1]. WebTo determine corrosivity, such a map should only need to identify the soil resistivity and pH of a certain site. The pilot test conducted using 40-point soil pH and resistivity data …
