A field experiment was conducted in 2015-2017, in the Production and Experimental Station located in Balcyny (51.6667 degrees N, 18.1667 degrees E). The surface area of a plot for harvest was 450 m(2). The following nitrogen fertilizers were applied in the experiment: UAN - 32%N, UAN+S - 26% N + 3% S, UAN+P (medium) - 26% N and 11% P2O5, UAN+P (starter) - 21% N and 18% P2O5, UAN+Mg - 20% N + 4% Mg. It has been demonstrated that the content of micronutrients in maize grain is modified more by the atmospheric conditions (year of cultivation) than by the tested fertilization. The highest content of Zn, Mn and B was determined in the grain harvested in the second year of the experiment, when total rainfall was slightly higher than the long-term average. In turn, when the rainfall was deficient in the first year, maize contained the highest levels of Cu and Fe. Fertilization had no effect on the content of copper and manganese in grain, while nitrogen fertilization lowered the content of B and Fe. The content of micronutrients in maize straw also depended on the year of cultivation and the relationships looked similar. Concentrations of B, Cu, Zn, Mn and Fe in maize straw were differentiated more by the applied fertilization. Significantly the highest amounts of B, Cu, Zn, Mn and Fe were removed with the maize aerial mass in 2016, when the meteorological conditions favoured the growth of this plant. The unit uptake of micronutrients for the production of 1 t of grain was also more considerably affected by the weather conditions than by the applied fertilization. The contribution of grain to the accumulation of micronutrients varied significantly between the years, and ranged for particular elements as follows: B - from 35 to 44%, Cu - from 28 to 34%, Zn - from 42 to 52%, Mn - from 7 to 13% and Fe - from 15 to 17%.
