Electrical Methods of Soil Moisture Measurement: A Review

Muktimani Brahma, Bikramjit Goswami


Soil moisture is an important factor that is of immense importance in the field of engineering, agriculture and ecology. The permittivity of soil is dependent on the water level present in the soil. Development of weather patterns and the production of precipitation depend on soil moisture. A number of soil moisture measurement techniques are being developed by various researchers. This paper reviews the various electrical methods of measuring soil moisture, such as the dielectric method, electrical resistance method and electrical capacitance method.
