In this paper changes in the manganese content in the sward and soil were presented on the basis of the experiment taking place in Czarny Potok near Krynica (20°54 E; 49°24 N), which was set up on natural mountain meadowland (Nardus stricta L. and Festuca rubra L. type) in 1968. The experiment conducted in series 0Ca and +Ca comprised 8 fertilized objects. The manganese content in the meadow sward depended on the cut, time, object and series. This content was usually lower in the 1st cut than in the 2nd and this difference grew less over the time of the experiment. After 35 years of the experiment, equalization of the manganese content in both cuts was observed. The amount of manganese taken up depended chiefly on doses conditioning the yield and acidification rather than on the nitrogen form. The highest yields were obtained between the 11th-17th years of the experiment. The average manganese uptake for these yields amounted to more than 4 kg Mn ha-1 for sward fertilized with 180 kg N ha-1 and around 3 kg Mn for sward fertilized with half the dose. Applied liming, which did not influence the yield, caused changes in the amount of manganese taken up. An examination of the manganese forms (total and mobile) in the soil confirmed the relation between the amount of manganese removed and sward yield and its lower content in the soil.
