Dielectric Behaviour of Indian Soil | Original Article

ABSTRACT

In this paper an attempt has been made to analyze as well as study the microwave dielectric behavior of soil in India. Soils are composed of solids, liquids and gases mixed together in variable proportions. Study of physical properties, chemical properties, dielectric properties of soil with varied organic and inorganic matter is useful in agriculture to predict quality and fertility of soil. Also it is useful for the researchers working in the field of microwave remote sensing. It has been observed that the dielectric constant of dry soil is less than three. Further it has been observed that dielectric constant of soil of different states UP, Kashmir, MH, Karnataka, WB, CG, Rajasthan, Kerala as 2.1, 5.0, 8.2,4.5, 3.5, 20.5, 10.5, 4.5,8.0 respectively. However, the relationship between soil dielectric constant and the soil physical properties is not straight forward. Soil plays a key role in various hydrological and meteorological applications. The moisture content in the soil affects the dielectric constant. The value of dielectric constant depends upon the percentage of moisture content in the soil. Soil characterization of a region is an important aspect in relation to sustainable agricultural productions.
