The aim of this study was estimation of total cadmium content and its fractional comp sition in arable soils, depending on their physicochemical properties. The research material co sisted of samples taken from arable soil in 81 points within then Podlasie Province. The conte of total cadmium in soils and its fractional composition was determined with the BCR method, was found that the total content of cadmium was typical for uncontaminated soils and ranged fro 0.11 to 1.59 mg kg1. The percentage ofacid in the soluble and exchangeable fraction fluctuati at around 10% on average. The reducible fraction comprised about 20% and oxidizable fractic 26%, on average. Most of the cadmium was in the residual fraction. The factors that influenct the fractional composition of cadmium were determined. For the very light and light soils it w mainly the content of magnesium and pH, while for medium soils it was the organic carbon ai magnesium content, content of soil fraction <0.02 mm, as well as the percentageof Cd in redu ible fraction.
