Extract

1. The equivalent parallel capacity and conductance of a series of soil blocks have been measured for decreasing moisture content.

2. The results obtained depend on the electrodes used. With mercury, all soils give curves of the same general type for the variation of the capacity with moisture because the capacity effects associated with the soil electrode interface are large compared with those due to the soil. The electrical properties of the interface have been shown to exhibit marked changes in their variation with moisture at certain moisture contents.
