Evaluation of the impact of soil contamination with mercury and application of soil amendments on the yield and chemical composition of L.

The purpose of this study was to determine the effect of soil contamination with Hg on the yield and chemical composition of L. Mercury was incorporated into soil in amounts: 0, 50, 100 and 150 mg Hg·kgof soil. Zeolite, lime and bentonite were used to alleviate the soil contamination.

Effect of soil contamination with fluorine on the yield and content of nitrogen forms in the biomass of crops.

The research was based on a pot experiment, in which the response of eight species of crops to soil contamination with fluorine was investigated. In parallel, some inactivating substances were tested in terms of their potential use for the neutralization of the harmful influence of fluorine on plants. The response of crops to soil contamination with fluorine was assessed according to the volume of biomass produced by aerial organs and roots as well as their content of N-total, N-protein, and N-NO.

Effect of organic matter and liming on the reduction of cadmium uptake from soil by triticale and spring oilseed rape.

The aim of the study conducted on triticale and spring oilseed rape was to determine the role of liming, brown coal and compost medium in reducing the effect of cadmium contamination (at the rates of 0, 7.5, 15 and 22.5 mg Cd kg(-1) of soil) on yield and chemical composition of the crop.
