Abstract:

The electrical properties of soils can be used to estimate soil characteristics such as moisture content and density. Relationships between the dielectric properties and soil moisture are the basis for the microwave remote sensing of soil moisture and some in situ soil moisture instruments. Several soil characteristics can produce the same set of dielectric properties and only through system design can any one be isolated with complete confidence. In recent years, investigations have been conducted to isolate the effects of specific characteristics through laboratory and field experiments. A review of the results of these studies is presented, and the following soil characteristics are included: soil moisture, soil texture, bulk density, structure, salinity, organic matter content, and temperature. Of these factors, the most significant and easiest to isolate is soil moisture. Of secondary importance are texture, density, and structure, depending on local conditions. Salinity, temperature, and organic matter content are of limited significance.
