When soil freezes, abrupt changes occur in the electrical potential measured between electrodes buried in frozen vs unfrozen regions. These "freezing potentials" can vary in polarity and magnitude depending on soil type, freezing rate, nature and concentration of electrolytes in the soil-water, etc. This report finds that electrical potential changes of the same order of magnitude as freezing potentials (i.e., about 100 mV) can be generated by simply compressing the soil at room temperature… CONTINUE READING
