Electrical and Physical Properties of Coimbatore Soils at Microwave Frequency
The aim of this paper was to study the variations of the electrical properties like electrical conductivity and dielectric constant of soils with their physical properties. Eight soil samples were collected from different locations of Coimbatore (Tamilnadu) at the depth of 0 – 15 cm. Soil samples were analysed for physical properties like texture, bulk density and porosity. The electrical conductivity is measured by soil testing kit Model 161E in the laboratory and dielectric constant of dry soil samples was measured at C- band microwave frequency. Correlations between electrical and physical properties of soil samples were studied. The results were analysed statistically to obtain correlation coefficients. Which showed that the electrical conductivity and dielectric constant both dependent on physical properties of soil and have significant correlations with them. Results obtained are useful in the field of remote sensing and agriculture.
