It has been found that it was nitrogen which exerted the strongest effect on the content of the macro- (N, N-NO3, P, K, Na, Mg, Ca) and microelements (B, Mn, Cu, Zn) in the period from May to October, somewhat weaker farmyard manure and lime. Along with increasing nitrogen rate increased more quickly the content of nitrate nitrogen than that of total nitrogen as well narrowed quantitative relations between the above N forms.
