Changes in the soil phosphorus content after triple superphosphate application into alkaline chernozem and the effect on yields of barley biomass

Popis výsledku v původním jazyce

Phosphorus deficiency is a main limiting factor for cereal production in many regions of the world. P deficiencies also diminished yield of barley. The significant decrease in use of mineral phosphate fertilisers began in the Czech Republic after political-social changes in the year 1989. More than 75% of arable land of the Czech Republic there for requires nowadays fertilisation with phosphorus. Soil testing is a remarkable and unique activity that synthesises a large amount of research information and scientific knowledge for practical needs of the identification and prevention of the majority of disproportions in plant nutrition in a given fields. In 2017 a pot experiment with four treatments (incl. unfertilised control treatment) was established with spring barley, variety KWS Irina, in the outdoor vegetation hall of Mendel University in Brno, Czech Republic. Chernozem (with a low supply of phosphorus and alkaline pH - 7,37) was used for this trial. The rates of phosphorus (0,3 – 0,6 – 1,2 g P per pot = 5 kg of soil) were increased by using the triple-superphosphate fertiliser (45% P2O5), treatments 2 – 4. Nitrogen was applied in the form of CAN (27% N) at a rate of 1 g N per pot in all treatments, inc. the control. The content of post-harvest soil phosphorus increased significantly with the applied rate (41 – 73 – 117 – 166 mg P /kg). Dry matter yields of above ground biomass increased significantly in all fertilised treatments as against the control (31,75 – 39,25 – 45,66 – 48,50 g DM per pot), without significant differences between too highest rates of P-fertiliser. Triple-superphosphate is a suitable P-fertiliser for increasing of soil P-content on alkaline soils with a joint effect on yield.
