The electrical properties of dry soil samples are found to be in good agreement with the earlier work.

From this data, the <i>ac </i>conductivity and relaxation time are also reported in the present paper. The result shows the change in electrical properties of soils before and after the addition of water. These results provide a basis for using ground-penetrating radar or other high-frequency electromagnetic sensors in the detection of soil moisture content.</span></span></span></span></span></span></span> |
