The research covered monocultures of Arrhenatherum elatius, Dactylis glomerata, Festuca pratensis and Phleum pratense as well as their two component mixtures with Galega orientalis. The ratio of Ca:P and K:(Ca+Mg) were generally within tolerable leveles under grass green growths in monocultures while the ratio K:Na was rather wide. The presence of Galega orientalis in the green growths in a decisive way widened the ratio Ca:P while narrowing that of K:Na and K:(Ca+Mg)
