Abstract
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.
