The grain yield of winter barley was significantly increased by 100 kg ha-1 year-1 N application by 39% (1.4 t ha-1). However, larger N doses, such as 200 and 300 kg ha-1 year-1 caused N over fertilisation and resulted in 0.2–0.4 t ha-1 decrease of grain yield. Cu fertilisation did not affect yield. The N load increased the N concentration of the vegetable organs and that of the examined cations. The N supply enhanced the Cu uptake of the above-ground organs more significantly than Cu fertilisation. However, the Cu content of the root increased 2–3 times as a result of applying N and Cu. As a consequence of the positive interaction between N×Cu, the measured amount of Cu in the control treatment (5 mg kg-1) increased 6 times to 29 mg kg-1. At the same time, the Cu which accumulated in the root was transported to above-ground organs only slightly or it was not transported at all. The vertical movement of Cu was blocked.
