Abstract
This experiment aimed at determining the effect of copper, zinc, tin and barium administered to soil at doses of 4, 40, 400 mg/kg on the contents of macroelements in spring barley and their correlations with the enzymatic activity of soil. The elements applied were found to be the most favourable for nitrogen accumulation in spring barely, however, the most beneficial effect was usually observed at their lowest (4 mg/kg) and medium doses (40 mg/kg). The highest increase in nitrogen content was evoked by zinc and copper. An increased zinc content of soil was accompanied by a rise in the contents of calcium, magnesium, potassium and partly phosphorus and sodium in plants. High doses of zinc resulted in decreased levels of phosphorus and sodium in spring barley. Copper contributed to an increase in the contents of calcium, sodium, magnesium and potassium, and a decrease in the phosphorus content of spring barley. Soil contamination with tin and barium was found to affect to the greatest extent the contents of calcium, magnesium and phosphorus, however, in the case of magnesium its effect was definitely negative, whereas in the case of calcium it was positive. The correlations between the activity of urease in the soil and nitrogen content of plant were usually negative, and between the activity of alkaline phosphatase and the phosphorus content of spring barley was usually positive.
