In the experiment a differentiated mineral NPK fertilization was applied on the background of constant fertilization with farmyard manure in dose of 25 t/ha. Two experiments were carried out, in which also differentiated mineral fertilization against the background of constant fertilizing with magnesium and liming was applied. The experiment was carried out on acid soil and very acid one. The crop rotation in both the experiments was similar, the differences pertained only to the variety of fodder plant. In the result of 4-year long intensive cultivation of plants in crop rotation and differentiated mineral fertilization the soil reaction of very acid soil changed for acid while that of acid changed for worse
