Precautions for use of Potassium Sulphate

Potassium Sulphate is an inorganic salt that is a white crystalline powder. There are many things to pay attention to when using it, let's take a look at it today.

Precautions for using Potassium Sulphate:
First, in acidic soil, excess sulfate radicals will increase the acidity of the soil, and even aggravate the toxicity of active aluminum and iron in the soil to crops. Under flooding conditions, excessive sulfate radicals will be reduced to hydrogen sulfide, which will cause the roots to suffer and turn black. Therefore, long-term application of Potassium Sulphate should be combined with farmyard manure, alkaline phosphate fertilizer and lime to reduce acidity. In practice, drainage and drying measures should be combined to improve ventilation.
Second, in calcareous soils, sulfate radicals and calcium ions in the soil form insoluble calcium sulfate (gypsum). Too much calcium sulfate will cause soil compaction, and attention should be paid to increasing the application of farmyard manure at this time.
Third, focus on the use of chlorine-avoiding crops, such as tobacco, tea trees, grapes, sugarcane, sugar beets, watermelons, potatoes, etc., the application of Potassium Sulphate not only increases the yield, but also improves the quality. Potassium Sulphate is more expensive than potassium chloride and has less supply. It should be mainly used in cash crops that are sensitive to chlorine and prefer sulfur and potassium, and the benefits will be better.
Fourth, this fertilizer is a physiological acid salt, and Potassium Sulphate can reduce soil pH when applied to alkaline soils.
