Investigations were made in 1977-79 on the three mountain meadows in Czarny Potok near Krynica (600-700 m a.s.l.). In experiments respected 3 frequences of mowing (2, 3, and 4 mowings). On the base each of this frequency used 2 levels of nitrogen fertilization. Moderately of increasing of number of mowings observed in green the increment of contents: P, K, Mg, and Na. At the same time thin down the proportions Ca:P and widen the proportion K:(Ca+Mg). But in influence of increasing doses of nitrogen, using on the base of determining number of mowings decreased the welfare plants in: P, K, and Ca thin down the proportion K:Na. The improvement of nourishment value of green on the influence of frequency mowing not enough significance for compensation the costs of increasing number of mowings
