The trial has been conducted at the roofless lysimetric station. Different ways of utilization of sandy and loamy soil and of swamp peat on content of nitrates, cadmium nickel and lead in infiltration water were followed. The content of nitrates was highest of all-around black fallow as on sandy soil, as on loamy and swamp soil. The most of nitrates were washed out from swamp soil containing high amount of organic matter, from black fallow on this soil more nitrates by about 65 % in total were washed out compared with the black fallow on sandy and loamy soils. Differences between ablation of risk elements from various ways of utilization were not mostly statistically significant.
