Abstract
According to the study results, the level of soil pollution with heavy metals in the northern part of Kryvyy Rih iron ore basin
(Kryvyy Rih district, Ukraine) reach to “moderately threating”. In the southern part of Kryvyy Rih basin (Shyroke district,
Ukraine) the level of soil pollution was between two assessments: “moderately threating” and “permissible”. The results of the
study on buffer capacity of usual black soils show that the tested elements can be arranged in the following descending order:
Pb>Cu>Zn>Mn. It was established that the introduction of quarry dust into soils can unbalance some of the main biochemical
processes, such as decreases in the activity of hydrolytic enzymes. Thiscan lead to an irreversible degradation of soils in the zone
of technogeneous pollution. When barley and soybean were grown in simulation studies, the introduction of quarry dust into soil
in a dose of 1% resulted in a 15 to 25% decrease in biological productivity of plants.
