Potassium sulfate fertilizer use precautions

First, in the acidic soil, the excess sulfate will increase the acidity of the soil, and even increase the soil of active aluminum, iron poisoning crops. In the flooding conditions, too much sulfate will be reduced to generate hydrogen sulfide, so that the root damage black. Therefore, the long-term use of potassium sulfate with farm manure, alkaline phosphate and lime with the reduction of acidity, in practice should also be combined with drainage measures to improve ventilation.
Second, in calcareous soils, sulfate and calcium ions in the soil produce insoluble calcium sulphate (gypsum). Too much calcium sulfate will cause soil compaction, this time should pay attention to increase farm manure.
Third, the use of bogey chlorine crops, such as tobacco, tea, grapes, sugar cane, beets, watermelon, potato and other potash increase not only yield, but also improve the quality. Potassium sulfate price is more expensive than potassium chloride, less supply, should focus on the use of chlorine sensitive and hi hi potassium on the economic crops, the benefits will be better.
Fourth, potassium sulphate fertilizer supplier is a physiological acidic salt, applied in alkaline soil can reduce soil pH.
