The paper presents the study results of mobile forms of Mn, Zn and Cu in irrigated fertilized and unfertilized chernozems typical. Irrigation affects the content and distribution of mobile forms of trace elements, increasing their removal beyond the 150 cm of soil layer. The fertilization increase the migration of Cu until 130 cm, fixed Mn and Zn in 0-60 cm of the irrigated soils. During irrigation constitutes a danger of soil contamination with Mn, Cu and Zn.
