nr 1

The aim of the experiment was to determine the effect of cadmium (10, 20, 30 and 40 mg Cd ˇ kg-1 soil) on phosphorus uptake in plants. Neutralising matter, including compost, brown coal, lime and bentonite, was introduced into the soil for a basic pot experiments. Correlation between the phosphorus content and the cadmium contamination in the soil, plant yield and the macro- and microelements content in the plants were determined. The effect of soil contamination with cadmium on the phosphorus content was related to the species and the organs of plants. High cadmium concentration in the soil caused the phosphorus content in the grain and roots of oats, in maize root and in the above-ground parts of yellow lupine to increase. Such a correlation was not observed for oats straw, roots of yellow lupine and above-ground parts and roots of radish.
