In the present work, an ecological investigation of the soils of the educational farm "Kanonerovskoye" of the Achinsk branch of the Federal State Budgetary Educational Institution of Higher Education "Krasnoyarsk State Agrarian University" was carried out. The content of humic substances in the alkaline extract was determined, and the contamination with salts of Cu, Ni, Mn, Zn, Pb, Cd, Co, Cr was assessed. The measured concentrations of mobile forms of heavy metals are within MPC. A slight excess of the concentration of copper sulfates was found. Based on the analysis of the spectra of the real and imaginary parts of the complex dielectric permittivity, as well as the dielectric moisture dependences, features were revealed that, possibly, in the future will make it possible to remotely study the soil for contamination with salts of heavy metals.
