abstract: Foliar fertilization with urea and nickel chelate Ni-EDTA and micronutrients fertilizers Plonvit Z and Plonvit R was applied in model pot experiment. The content of Zn and Ni in washed and unwashed plants of wheat and spring oilseed rape was determined with AAS method. Foliar fertilization with micronutrients increased the content of zinc and nickel in plants. In a weak period after foliar application the content of both nutrients in unwashed plants was higher than in washed ones. Zinc was easier displaced from vegetative mass into seeds than nickel.
