The effect of location (Kromeriz, Zabcice (Czech Republic)) and year (2005, 2007 and 2008) on the content of mineral elements and basic grain chemical composition (N-substances, starch, fat, fibre) was studied in seven spring malting barley cultivars (Amulet, Bojos, Jersey, Malz, Prestige, Sebastian and Tolar) grown under a cropping system with restricted chemical treatment. Considering the requirements for the levels of macro- and microelements for good growth, development and fermentation activity of brewers' yeast, the best cultivars were Amulet and Prestige, cv. Bojos ranked among the cultivars with low concentrations of all macroelements and the lowest concentrations of microelements were characteristic for cv. Sebastian. The levels of the examined nutrients, minerals and heavy metals were significantly influenced by all factors studied, i.e. cultivar, location and year. There was a significant difference among cultivars in the concentrations of P, B, Cu, Fe and Ca to Mg ratio. The concentrations of minerals were significantly influenced by grain weight.
