Study of two Indian soils

V. V. Navarkhele

Abstract

The paper presents the study of two Indian soils of different colors. It consist microwave dielectric measurement and its comparison with the polynomial empirical model of Hallikainen. The objective of this study was to determine the physical, chemical compositions of these two soils and its behavior for agricultural purpose. The variation in resistivity with water content, physical- chemical properties of the said soils has been also reported in the paper. The dielectric properties that is, dielectric constant (e¢ ) and dielectric loss (e″) has been reported at microwave frequency using transmission line waveguide technique. The comparative dielectric study show that there is variation in (e¢ ) and (e″) though the texture composition of the two soils is approximately same. The gravimetric water content (θg), volumetric water content (θv), water holding capacity, bulk density, conductivity, PH and total dissolved solids are also calculated to study the soils behavior for agricultural purpose.
