In 2016 a pot experiment (5 kg of soil -- Mitscherlich pots) with 4 treatments (incl. unfertilized control treatment) was established with spring barley, variety KWS Irina, in the outdoor vegetation hall. Haplic luvisol from Jaroměřice nad Rokytnou (with a good supply of magnesium and slightly acid soil reaction -- 6.01) was used for this trial. The rates of magnesium (0.075 - 0.15 - 0.3 g Mg per pot) and sulphur (0.1 - 0.2 - 0.4 g S per pot) were increased by using the ESTA Kieserite fertiliser (25 % MgO; 20 % S), treatments 2 - 4. 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 magnesium and sulphur increased significantly with the applied rate (196 - 227 - 261 mg Mg/kg and 40.1 - 76.8 - 208.6 mg S/ kg, respectively). The soil reaction (pH) increased significantly in all the fertilised treatments (6.42 - 6.57 - 6.60) against the unfertilised control treatment (6.10). Dry matter yields of the aboveground biomass (41.75 - 42.25 - 44.75 - 44.25 g DM per pot) increased significantly only when the two highest rates of fertilisers were applied (44.75 - 44.25 g DM per pot) as against the other treatments.
