This paper informs about N, P, K, Ca and Mg concentrations in tissues of 4-year old Norway spruce and 3-year old European beech transplants after two years of Mg fertilization (100 kg Mg/ha/year) in the form of magnesium sulphate, and N fertilization (100 kg N/ha/year) in the form of ammonium sulphate. Analyses of buds, needles/leaves, bark, wood, fine and small-diameter roots showed that the greatest amounts of uptaken nutrients are in both tree species stored in assimilatory organs and in buds. The increased supply of N was mostly in small-diameter roots (spruce), and in root-wood, wood of stem and branches (beech). The two species responded to the increased supply of Mg by increasing the bioelement content in root-wood and in fine roots. The increase of Mg concentration in leaves occurred only in the second year of fertilization.
