Sažetak
The quality and some minerals contents were followed in the green mass and hay from different localities on Divčibare. Samples were taken from three different altitudes, up to 250 m, from 250 m to 550 m and over 550 m above sea level. Twelve samples of early bloom plants were taken
(four samples of green mass from the same altitude), and after mowing, samples of hay were also taken from the same meadow. The samples were prepared from ashes by use of atomic absorption spectrophotometry (AAS) macro- and microelements content was determined, while the phosphorus content was determined by application of standard methods. Average calcium content in the plants valued 5.85 g/kg, phosphorus 2.41 g/kg, magnesium 2.47 g/kg, sodium 0.93 g/kg and potassium 10.35 g/kg in dry substance. In the samples of hay, macro elements content was 6.65, 1.56, 1.54, 0.78 and 10.76 g/kg respectively. Average iron content in the samples of plants from Divčibare region amounted to 171.87 mg/kg, copper 5.12 mg/kg, zinc 21.67 mg/kg, manganese 63.97 mg/kg and
selenium 17.17 μg/kg in dry substance. The average amount of iron 92.47 mg/kg, 4.75 mg/kg copper, 19.65 mg/kg zinc, 113.29 mg/kg manganese and 26.00 μg/kg selenium were found in the hay from the same localities.
