Sažetak
Phosphorus (P) belongs among macronutrients and its interaction with other nutrients significantly contributes to optimum crop yields and nutrients utilisation efficiency. As part of the research project a pot experiment was established with spring barley, variety KWS Irina. The experiment was conducted in the vegetation hall of the Botanical Garden of Mendel University in Brno, Czech Republic. The soil (cambisol) had a good supply of phosphorus – 113 mg kg-1 (Mehlich 3) and slightly acid 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 significantly with the applied rate (173 – 221 – 295 mg kg-1). Dry matter yields of the aboveground biomass were the lowest in the control treatment not fertilised with P (40.3 g per pot) and increased significantly with the P rate applied (45.1 – 45.4 – 43.7 g per pot) without any significant differences among all fertilized rates. The results showed that the application of water- soluble phosphorus forms in soils can significantly increase the P content in soils with a good phosphorus supply moving to higher categories of supply. Therefore, it is very important that fertilisation of crops be based on the soil supply of P.
