The subject of the paper was to determine chromium and cadmium fractions in the soils treated with tannery organic materials. Methods, characteristics of experimental materials and the tested soils were presented in the first part of the paper. After four years of investigations soil samples were collected for the assessment of the total content of chromium and cadmium and their fractions. Results of a sequential chemical extraction confirmed literature data on the weak mobility of this metal in the soil. After application of the studied fertilisers, the share of the most mobile Cr fractions was slight. Iron oxides and residual fractions were most important for chromium accumulation. Cadmium mobility in the soil and its easy uptake by plants is related to a considerable share of mobile forms. A large share of mobile form was noticed in the analysed soils (54.5-68.3%). Exchangeable fraction bound smaller amounts of cadmium (6.8-13.2%). Similar amounts of cadmium were accumulated in the fractions bound to manganese oxides (8.5-19.6%). Organic matter did not contribute to this element binding and the amounts of cadmium stored in this fraction were 2.3-6.6%. Only very small amount of cadmium was accumulated in the form bound with the initial minerals.
