Basing on the results obtained as well as the analysis of equations of multiple regression and their coefficients of correlation the author ascertained that the content of Cu in the upper leaf of winter wheat is conditioned not only by the content of Cu in a definite soil extract but also by the hydrolytic acidity of the soil. The content of zinc in the tops of winter wheat is very strongly correlated with the amounts of this element determined in the 0.1 M or 1 M HCl extracts as well as the total exchangeable bases in soil (R = 0.99). No significant effect of the investigated soil features on the content of manganese in winter wheat was found
