Measurement and Application of Electrical Properties of Soils
Conventional geophysical methods for estimating soil properties require soil sample to be removed from the ground and disturbs its in situ state. It also requires large number of samples to be tested for getting precise results, so it is not cost and labor effective. Now slowly these methods are being replaced by electrical geophysical methods, which are quick, efficient, precise, labor effective and cost effective. These methods are based up on measuring electrical properties of soil and subsequently relating them to other soil physical properties. Though these methods need a prior calibration, but once it is calibrated it serves as very quick and efficient tool for keeping track of state of soil. Objective of this study is to throw some light on methods for estimating electrical properties of the soil mass and how efficiently they can be used for estimating its other physical properties.
