For its specific physical and physicochemical properties, the water treated with low-frequency low-pressure glow plasma (GPTW) affects the growth of plants and enhances the phytoavalibility of selenium (Se) ions from the nutrient solution. The basic biometric and physiological parameters of cucumber and the uptake of Se ions applied as selenate (Na2SeO4) from the nutrient solution prepared using GPTW or distilled water (DW) were compared. In the presence of Se, the fresh weight (f.w.) of shoots of plants growing in waterdifferentiated nutrient solutions did not differ, whilst their dry weight (d.w.) and leaf area (LA) were higher in plants grown in the GPTW- than in DW-containing medium. The use of GPTW for preparation of the nutrient solution was associated with a substantial improvement of Se ions phytoavailability, compared to the regular growth medium based on DW. Despite the higher Se bioaccumulation in the GPTW- than in DW-based medium, the phytotoxicity of this element was not enhanced. GPTW-induced Se accumulation was remarkable and hence recommended for further study to understand the detailed mechanism GPTW action.

The present paper reviews content and phytoavailability of heavy metals (Cd, Cu, Ni, Pb, Zn) in the soils of seven selected regions in the former Tarnów province, considered to be particularly endangered by contamination by these metals. One hundred soil samples were collected, 50 from the 0-10 cm layer and 50 from the 40-50 cm layer and mixed meadow sward from the same places. Most of the examined soil samples had a natural heavy metal content with the exception of a few samples containing higher amounts of Cd, Ni, and Zn. A strong correlation between heavy metal content and soil sorptive capacity and the organic matter content and the level of soil fraction with particle diameter of <0.02 and <0.002 mm was observed. Analysis of heavy metals in plants revealed that the limit values of Cd and Zn content were exceeded only occasionally together with reduced fodder quality of the investigated sward.

The aim of this study was to assess the influence of mineral NPK, Mg and micronutrient fertilisation on the content of macroelements and root yield of a sugar beet cultivar called Khazar. The effects of three fertilisation levels were assessed. Additionally, the highest NPK dose was analysed in treatments with NPK + Mg and micronutrients (B, Cu, Zn, Mn). The increasing level of NPK fertilisation as well as the nutrition with magnesium and micronutrients caused an increase in root yield. The highest yield of roots was achieved by beet plants fertilised with the high NPK dose combined with magnesium, boron, copper and zinc. It was demonstrated that roots fertilised with the 3NPK dose and magnesium tended to accumulate more N-total. At the same time, the applied micronutrients contributed to a decline in the N-total content of dry matter in roots. The analysed fertilisation with NPK and micronutrients did not affect the content of phosphorus, potassium and calcium in either of the two beet organs. In general, beet leaves were characterised by higher concentrations of nutrients than roots.
