The knowledge of interactions between nitrogen and other nutrients and trace elements is the key to improving the uptake of nutrients. A study on a grapevine cultivar called Bianca was carried out in the Garlicki Lamus vineyard located in Garlica Murowana (near Krakow, Poland) in 2010-2011. The plants were treated with three nitrogen doses (0, 50 and 100 kg N ha–1) supplied as ammonium nitrate in a single application at three weeks pre-flowering. Samples of leaf petioles and blades, as well as grapes were taken. After wet microwave digestion in HNO3, some nutrient elements: B, Cu, Fe, Zn, Mn, Mo and Na, as well as trace elements: Al, Ba, Cd, Cr, Li, Ni, Sr, Ti and V were measured using the ICP-OES technique. Concentrations of microelements in the grapevine tissues were in the optimum (B, Cu, Fe, Zn and Mo) or high (Mn) range of content reported for ‘full bloom’ plants. N fertilizers enhanced leaf accumulation of trace elements such as Ti and V or depressed the uptake of some elements like B, Mn, Ba, Cd and Sr. Analyzed leaf blades contained higher amounts of Fe, Mn, Al, Ni, Pb, Ti and V than petioles. In contrast, petioles had more B, Zn, Mo, Cd, Ba, Li and Sr. Increased N fertilization diminished Cd and Ti (only at 50 kg N ha–1) in grape must; the reverse was true for Ba and Sr. The vintage strongly influenced grape mineral content. During warmer and wet year 2010, higher amounts Al, Cu, Fe and Ti were measured in fruits. The dry season in 2011 increased the content of Mn, B, Cd, Cr and Ni in fruits.
