The “Wenner Four Electrode” method; and the “Barnes Layer” method of computation, for the electrical soil resistivity, are both time consuming but very useful and reliable. Pre-measured cables can simplify and reduce the field time by at least 75 percent. A computerized program for calculation and graphical representation could achieve the same savings, when compared with manual production.
