In the samples of alluvial meadow soils (irrigated and non-irrigated) in the Lower Dniester River were determinate the Cu, Zn, Co, Ni, Pb, Cd, Cr, Mn contents and their vertical distribution. The results indicated that irrigation has led to obvious accumulation of heavy metals in the alluvial soil: in the humiferous, gleyic and carbonatic horizons in different concentration. The non-irrigated fallow alluvial soils differ from the arable irrigated soils by a higher content of elements in profile, especially in the humiferous horizon, which is related to the specific conditions of their genesis, geomorphological characteristics, the hydrological regime etc. Thus, in the alluvial soils, approximately 50% of the total reserves of mobile forms of microelements are concentrated in the upper part of the soil profile (0-38 cm).
