The effect of artificial forest plantations on electrical resistance, electrical conductivity (Cond), mineralization (TDS), salinity (Salt) and dielectric constant of ordinary chornozem in the conditions of Pyatikhatsky forest range (Dnipropetrovsk region, Ukraine) was studied. Determination of the electrical resistance of the soil paste was performed using a four-electrode installation with planar electrodes. The determination of the electrophysical index of the soil suspension (conductivity, mineralization and salinity) was performed using an Ezodo-7021 –conductometer-salimeter-thermometer. Determination of the dielectric constant of the soil was performed using a CM-9601A – digital capacitance meter. It has been established that the upper genetic horizons of chernozem under the steppe vegetation and the planting of robinia are characterized by increased electrical resistance as compared with the upper horizons of the chornozem under the oak plantation. The upper horizons of chornozem under steppe vegetation and robinia plantation are also distinguished by reduced values of electrical conductivity, mineralization and salinity compared to the upper horizons of chornozem under oak plantation. This pattern of distribution of the studied parameters may indicate the removal of water-soluble and nutritive compounds from chornozem under the steppe vegetation (used for growing agricultural plants) and robinia plantation, while their accumulation is observed under the oak plantation. The upper horizons of the chornozem under the steppe vegetation are distinguished by increased values of the dielectric constant compared with the upper horizons of chornozem under the plantations of robinia and oak. This indicates the compaction of chornozem under the steppe vegetation, which occurs as a result of its depletion on the content of organic substances and the decline of the structural-aggregative state. The results obtained suggest that artificial forest plantations have a favorable effect on the properties of ordinary chornozem, and the electrophysical index can quite fairly be used as certain «markers» of the state of chornozem.
