Product Details

1. Product description:

Potassium sulfate is a kind of high-component quick-acting potassium fertilizer, mainly prepared from sulfate ore anhydrous magnesia and potassium chloride as raw materials. It is white or light yellow crystalline particles, and has two crystal forms: α-type and β-type . α-type is colorless crystal of hexagonal system, β-type is colorless crystal of orthorhombic system. It has a bitter and salty taste. Generally, it contains 90%-95% potassium sulfate, 50%-52% potassium (K2O), 16% sulfur (S), and less than 2.2% chlorine (Cl); in addition, there are still a small amount of sodium (Na) and calcium ( Ca), magnesium (Mg) and bromine (Br), etc. Chemicalbook is insoluble in ethanol, acetone and carbon disulfide, but easily soluble in water, can be directly absorbed and utilized by plants, and can be used as base fertilizer, seed fertilizer and top dressing. Experiments have proved that the application of 1 kg of potassium sulfate can increase the yield of food crops by 6-8 kg, and the yield of sugar beet by 15.5-22.5 kg. Some crops that avoid chlorine (such as fruits, flax, tobacco, tea, citrus, potatoes, etc.) can not use potassium chloride, but can use potassium sulfate. Applying potassium sulfate to acidic soil requires proper application of lime or mixed application with phosphate rock powder fertilizer, which can increase the utilization rate of phosphorus without increasing the acidity of the soil.

Potassium sulfate dissolves in water immediately after being applied to the soil and dissociates into K+ and SO2-4; part of K+ is absorbed by plants and produces a physiological acid reaction, and the other part of K+ is absorbed by soil colloids and exchanges Ca2+ and other positive Chemicalbook ions into the soil. In the solution, it forms CaSO4 with the remaining SO2-4; the latter has low solubility and is not easy to lose with water. In neutral and calcareous soils, the effect on the degree of decalcification and acidification of the soil is light.
