Abstract

This research paper explores the effects of interfacial polarization in soil mixtures from a dielectric perspective, focusing on Indian soils characterized by diverse textures, compositions, and moisture levels. The study investigates how moisture content, soil texture, mineral composition, and temperature influence the dielectric properties of soils. Experimental results reveal that higher moisture content significantly increases the dielectric constant, with clayey soils demonstrating the highest values due to their greater water retention capacity. Frequency-dependent behaviour shows a decrease in dielectric constant at higher frequencies, reflecting reduced polarization effects. Soil texture and mineral composition also play crucial roles, with clay-rich soils exhibiting stronger dielectric properties compared to sandy soils. Temperature variations further affect dielectric behaviour, with higher temperatures reducing the dielectric constant. The findings have important implications for practical applications, including soil moisture sensing in agriculture, environmental monitoring for soil contamination, geophysical surveys, and civil engineering for assessing soil stability. Understanding these dielectric properties aids in optimizing soil management practices, enhancing agricultural productivity, and improving infrastructure development, particularly in the diverse climatic and soil conditions of India.
