The trials were conducted in three series: without Actinomyces, with Actinomyces inoculum consiting of Streptomyces odorifer and Streptomyces viridid spores. Yield of spring barley and concentration of macroelements depended on the type of soil, application of Actinomyces inoculum and rate of contamination with copper. The content of all macroelements except phosphorus was higher in plants grown in light soil rather than in light clay sand. In general, soil contamination with copper had a positive effect on accumulation of macroelements in spring barley, increasing their levels in aboveground parts of plants. A particularly high, nearly 3-fold increase was observed in the case of calcium on light soil. Application of Actinomyces spores to soil limited the accumulation of macroelements in spring barley under the effect of copper. Nitrogen, calcium and magnesium were more strongly affected by Streptomyces viridis, whereas Streptomyces odorifer had a more pronounced effect on phosphorus, potassium and sodium. The levels of nitrogen, phosphorus, potassium and sodium were correlated with the yield of barley and with the concentration and uptake of other macroelements by spring barley
