Abstract

Pot experiments were conducted to study metal variations in the soil and stimulate transfer of the metals to more available for plants form. Soil was sampled in two sites: contaminated soil was taken near road with heavy traffic and clean soil was taken from park protected from the road by buildings. Differences between concentrations of the elements in leaves of the wheat grown in the clean and contaminated soils were statistically significant at P < 0.01. Cultivation of wheat as fast growing plants resulted in variations in concentrations of several macro- and trace elements in the soils. The response to the wheat growth was site-specific and mainly concerned essential nutrients, e.g., B, K, Na, P, S, and Sr. Amendment of the contaminated soil with urea and manure showed a decrease of Al, Cd, and Zn concentrations in the soil. The best effect was demonstrated after application of "ispolin": over a short period (36 days) concentrations of Al, Cd, Cu, Pb, and Zn in the soil decreased 1.2-1.4 times in comparison with those in the initial contaminated soil.
