In the present research work, studies on correlation factors of electrical conductivity and dielectric constant of black soils with physical properties and macro- and micronutrients of black soils are reported. Soil samples are collected from eight different locations covering North Maharashtra Region (India). An automated C-band and X -band microwave set-ups in the TE10 mode with Gunn source operating at frequencies 4.6 GHz in C - band and 10 GHz in X - band , are used for measuring dielectric properties. Our results show significant positive correlation of electrical conductivity and dielectric constant with majority of soil parameters except those with sand, bulk density, pH and CaCO3. Further, values of correlation factor are relatively more at C-band microwave frequency than X-band. Besides agricultural applications, such studies may find importance in better understanding of soil physics and also for analyzing the satellite data in remote sensing.
