摘要：An automated C-band micro wave set-up in the TE 10 mode with Gunn source operating at frequency 5.3 GHz is used for measuring dielectric properties of soils. Soil samples are collected from four different locations lying in the Indore district of Madhya Pradesh state (India). The parameters such as a. c. electrical conductivity (σ), and relaxation time (τ) of soil are determined from the experimentally measured values of complex dielectric constants of soils. Statistical correlation coefficient of a. c. conductivity and relaxation time of soils with moisture content for these soil samples are reported. For all the soil samples, the dielectric constant (ε') and dielectric loss (ε'') in general, are found to increase with increase in percentage gravimetric Moisture Content (MC %). Further, our results giv e high degree positive and relatively small negative correlation coefficient for a. c. conductivity and relaxation time respectively with MC (%) for all the four soil samples studied.
