Crop production is among others an economic activity, and farmers should have a profit from the fertilizers use. To test the profitable use of fertilizers in different climatic and soil conditions, a five years’ experiment was set up in the Czech Republic (CZ), Poland (PL), and in Albania (AL) in a rotation scheme with potato, as the main crop, preceding winter wheat and winter barley. In all the experimental sites, potato was the crop that reacted better to K fertilization, showing the highest profit compared with the other crops. The benefit of the farmers using fertilizers in the potato-cereal rotation reached than 11.200 Euro ha−1 in Albania and 3.000 and 4.100 Euro ha−1 for The Czech Republic and Poland, respectively. The beneficial profitable effect of K fertilization was recorded also in the second year after its application, in turn increasing economic benefits in barley production. The highest benefit was achieved when the requirements of the main crop, i.e. potato was fully covered by application of three essential nutrients, i.e. N, P and K. The balanced application of the three nutrients, not only affected positively the yields, but also contributed to increase the farmers’ incomes.
