The aim of the study were stable fertilization experiments in which was possible to investigate on different crops the influence of increasing doses of potassium in dependence on soil pH and magnesium content. The lower doses of potassium (83 kg K/ha) significantly increased yields of potatoes, spring barley, Italian rye grass, seradella and winter rape of 12 species grown on acid soils. The higher dose of potassium (166 kg K/ha) did not increase yields of any plants. The highest yields of all plants examined, were obtained on plots limed and fertilized with K and Mg
