Abstract
The aim of this study was estimation of pseudo-total nickel content and its fractional composition in arable soils depending on their physicochemical properties.The research material consisted of samples taken from arable soil in 81 points of Podlasie Province. The content of pseudo-total nickel in soils and its fractional composition was determined with BCR method. The correlations between pseudo-total content of nickel, as well as its individual fractions and physicochemical properties of soils were evaluated. It was found, that pseudo-total content of nickel was typical for uncontaminated soils and ranged from 2.0 to 14.4 mg kg. The share of acid soluble and exchangeable fraction was above 20 %, as compared to pseudo-total content. Reducible fraction comprised 20–40 %. The most of nickel was bound to organic matter. The factors which influenced fractional composition of nickel were determined. For the light soils it was content of soil fraction < 0.02 mm, granulometric composition and pH, while for medium-heavy soils, organic carbon and magnesium content, granulometric composition and content of soil fraction < 0.02 mm. The factors related to the changes of Ni content in light soils in fraction II and IV and for medium-heavy soils in fraction I, were not determined.
