Chemical analysis showed that the soil is characterized by acid reaction, high content of potassium, magnesium, calcium and sodium, but very low of phosphorus content. Since there is no mineral or organic fertilization on the area under study, macro- and microelement content of the soil depends on natural chemical properties. The results presenting the content of macroelements in the sward reveal a very low content of phosphorus, potassium, magnesium and calcium, whereas the concentration of sodium exceeds many times the optimum content for a good feed. There is a high content of manganesse and iron and too low copper content. The level of the elements in the soil affected their content in the sward, mostly that of sodium, manganese and iron
