The research aimed to determine the influence of Cr(III) and Cr(VI) in doses of 0 (control), 25, 50, 100 and 150 mg Cr.kg−1 of soil as well as compost, zeolite and CaO additives on the content of heavy metals in the spring oilseed rape (Brassica napus var. oleifera) and yellow lupine (Lupinus luteus L.). The contents of heavy metals (Cr, Zn, Ni, Cu) in plants, were determined using the method of spectrophotometry. All of the investigated element contents in the tested plants differed significantly in the case of applying amendments to the soil, as well as increasing concentrations of Cr(III) and Cr(VI). In the series without additives in soils containing Cr(III) and Cr(VI), rapeseed was characterized by a higher average content of Cr than yellow lupine. Compost most noticeably limited the negative effect of chromium. Cr(VI) modified the contents of trace elements in the tested plants more significantly than Cr(III).

The research was conducted as part of a project no N305 1059 33 and supported by Polish Ministry of Science and Higher Education.
