Abstract
The potassium supply is important in strawberry production. Potassium plays a role in the plant’s water management, promotes the cell elongation, it takes part in the synthesis of all kinds of carbohydrates: sugar, starch, and cellulose. Strawberry that is well supplied with potassium synthetizes more sugar, so the yield will be sweeter. In plant production mostly the potassium chloride is used as potassium fertilizer. Some plants – and so strawberry as well – react sensitive to chloride ions, because high chloride-concentration hinders the translocation of assimilates. Therefore the application of chloride-free fertilizers such as potassium-sulphate might be reasonable. Besides potassium, magnesium plays also a relevant role in plant life. It is important to watch out on magnesium supply on soils that are treated with a higher dosage of potassium, because of the antagonism between different ions, high potassium content can hinder magnesium utilization. To study the potassium and magnesium supply of soils we set up field experiments in acidic sandy soil with different fertilizers, such as potassium-chloride, potassium-sulphate and Patentkali (that contains also magnesium-sulphate beside potassium-sulphate). It was stated, that the most favourable conditions for the strawberry development were ensured by the treatments with a combination of potassium-sulphate and magnesium-sulphate. The positive effect was confirmed by the statistical analysis at P = 0.1% probability level. Nutrients applied in form of sulphate inhibited the uptake of chloride-ions. It is presumable, that the decrease in the chloride-ion concentration of plants contributed to the yield increment.
