Much like the Wenner method but entails a distinct spacing on the electrodes, this technique is highly successful for measuring deeper soil resistivity. Measurements will replicate the historic climate in the region, as resistivity in the soil is afflicted by temperature. As discussed inside the Seasonal Analysis for Grounding Techniques https://donovanxjvcl.onesmablog.com/new-step-by-step-map-for-soil-resistivity-survey-bd-72780931
