Rezumat: Balanced nutrition and fertilisation is essential for soil fertility and a prerequisite for achieving adequate yields and quality of production. As part of the national research project a pot experiment was established (Mitscherlich pots) with spring barley, variety KWS Irina. The experiment was conducted in the vegetation hall of the Crop Research Institute in Prague. The soil (chernozem) had a satisfactory supply of phosphorus – 57 mg/kg (Mehlich 3) and alkali soil reaction. The rates of phosphorus in the form of triple superphosphate (45% P2O5) were increased from 0.3 – 0.6 – 1.2 g per pot (5 kg of soil). Nitrogen was applied in the form of CAN (27% N) at a rate of 1 g N per pot in all the treatments incl. the control. The content of post-harvest soil phosphorus increased with the applied rate (65 – 90 – 116 mg/kg). Dry matter yields of the aboveground biomass were the lowest in the control treatment not fertilised with P (63.3 g per pot) and increased significantly with the P rate applied (66.7 – 68.6 – 70.7 g per pot).
