The effect of legumes on nutrient content in grasses growing in grass/legume mixtures

In years 1997-1998 experiments were carried out with the aim to determine the influence of leguminous plants (Trifolium pratense -and Medicago media) on the concentration of essential elements in grass components(Lolium multiflorum and Festulolium) of four grass/legume mixtures. Generally speaking, the effect of legumes on concentrations of macro-elements was only slight, albeit, a distinct decline in the concentration of nitrogen, magnesium and calcium were observed in Lolium multiflorum grown in combination with Trifolium pratense. from the point of view of nitrogen, phosphorus, potassium, magnesium and zinc contents, the mixture with the domination of Festulolium and Medicago media deserves special attention.
