Potassium sulphate is a kind of chlorine-free, high-quality and high-efficiency potash, especially in the cultivation ofchlorine-sensitive crops such as tobacco, grape, sugar beet, tea tree, potato, flax and various fruit trees. It is also an indispensable important fertilizer; it is also high quality. The main raw material of nitrogen, phosphorus and potassium ternary compound fertilizer.
First, in acidic soils, excess sulfate will increase the acidity of the soil and even increase the toxicity of active aluminum and iron in the soil. Under flooding conditions, too much sulfate will be reduced to form hydrogen sulfide, causing the roots to become black. Therefore, the long-term application of potassium sulfate should be combined with farmyard manure, alkaline phosphate fertilizer and lime to reduce the acidity. In practice, it should also be combined with drainage and drying measures to improve ventilation.
Second, in calcareous soils, sulfate and calcium ions in the soil produce calcium sulfate (gypsum) that is not easily soluble. Too much calcium sulphate will cause soil compaction. At this time, we should pay attention to the application of farmyard manure.
Third, the key use in the avoidance of chlorine crops, such as tobacco, tea trees, grapes, sugar cane, sugar beets, watermelons, potatoes, etc., increased potassium but not only increased yield, but also improved quality. The price of potassium sulphate is higher than that of potassium chloride, and there are few sources of supply. The focus should be on economic crops that are sensitive to chlorine and sulphur and potassium. The benefits will be better.
Fourth, the fertilizer is a physiologically acidic salt that is applied to alkaline soils to reduce soil pH.
