The paper presents microelements content in vegetation of mountain grasslands. Samples of the sward were taken from Ujsoly commune situated in the southern part of Beskid Zywiecki with altitude 540-1324 m a.s.l., in a strongly formatted terrain with a slope reaching 30-50 deg C. The vegetation from Zlatna contained the most of microelements, and the lowest Fe, Zn and Cu levels were observed in Soblowka. Fe content in the sward from Ujsoly and Zlatna was more diversified than in the other localities. More than half of the samples had optimum Fe content, and all samples of the sward from Soblowka and 50 percent from Glinka revealed its deficit. Mn level in the sward from Soblowka showed the greatest variability. Mn deficit was confirmed in 4 percent of sward samples, 8 percent - had optimal its level, and 88 percent its excessive concentration. Zn content was the most diversified in the sward from Zlatna, and in the other localities it proved smaller variability. Too low Zn level was observed in 38 percent of sward samples, 54 percent had optimum Zn content, and in 8 percent its excessive quantity was confirmed. Cu level was more diversified in Soblowka and Ujsoly than in the other two localities. All sward samples revealed a deficit of Cu. Zn and Cu in vegetation were positively correlated with their soil content, and Zn and Mn demonstrated a negative correlation with soil pH. Moreover Zn, Mn and Cu content was positively correlated with total N content in sward, and Zn and Cu - with Fe content in sward
