Increasing amounts of cadmium are being added to soils through sludge and fertilizer applications, especially phosphate. Cadmium deserves special attention because of its zootoxicity and relatively large mobility with respect to plant uptake and leaching. Soil pH appears to be one of the most important soil properties that determine Cd sorption. Other factors such as mineral composition, organic matter, cation exchange capacity, concentration of iron and manganese oxides and hydroxides have also shown the extent to which Cd is adsorped by the soil. Preliminary results on selected Slovak soil types unambiguously confirm the primary influence of soil pH and the partial influence of cation exchange capacity on extent of soil cadmium sorption
