The present study considers the crossover of the real part spectra of the complex dielectric constant obtained in the frequency range from 15 MHz to 15 GHz and temperature range from 0 to 25 °C for moist organic soils with the content of organic matter varying from 11 to 54 %. Based on the obtained experimental dependences, the empirical model is proposed to estimate the average value of the frequencies at which the crossover point of the soil dielectric constant spectra are observed with temperature changes. The proposed model also includes a formula for calculating the value of volumetric moisture at which the crossover point of the soil dielectric constant spectra appears.
