In a finished field experiment N, P, K, Ca, Mg, Na, Zn, Ni, Pb and Cd contents were compared, as well as interrelations between some elements in plants and silages of red clover and Italian ryegrass cultivated pure and in mixtures. Separate cultivation (pure sowing) or red clover sowing in a mixture did not diversify the contents of most macroelements in plants. An interaction of sowing with cut markedly affected magnesium content in red clover plants, while Mg amount in ryegrass was significantly differentiated in the result of cooperation of the years of cultivation and methods of sowing. Relations between macroelements revealed changes in the years and cuts.
