Abstract


The objective of this paper was to study the variability of the dielectric constant of dry soils with their physical constituents and available nutrients. The soil samples were collected from 10 different locations of North Maharashtra region at the depth of 0 15 cm. The soils were found to be slightly alkaline, non-saline and moderately calcareous in nature. Soil samples were analyzed for physicochemical properties and for the status of available nutrients. The dielectric constant of dry soil samples was measured at C- band microwave frequency 4.5 GHz and its variations with physical constituents and nutrients of soil samples were presented. The results were analyzed statistically, which showed the strong significant correlation between dielectric constant and texture of the soil. Similarly significant correlation was observed between dielectric constant and available nutrients in the soil except nitrogen, phosphorus and manganese.
