The article considers the role of GPR in solving problems of soil science, as well as the accuracy of tracking soil horizons using the example of field data. The study of the current state of the issue has shown that there is significant variability in the electrophysical properties of different types of soil. In this case, the dielectric constant of the soil horizons can both increase and decrease with depth. This fact determines the need for parameterization of the soil profile in GPR studies to prevent errors. Based on a generalizing analysis of practical examples, it has been established that the error in determining individual soil horizons by a GPR is on average 2–10 cm, depending on the frequency of the GPR antenna and the structural features of the soil. Experimental and methodological work to substantiate the main conclusions was carried out to trace the soil horizons by the GPR method using the example of typical entic podzol located on the Zaonezhsky Peninsula (Republic of Karelia), the structure and composition of which were described in detail earlier. The survey was carried out by a georadar OKO-2 (Logis-Geotech, Russia) with an antenna unit with a central frequency of 400 MHz.
