Potassium sulphate, also called SOP fertilizer, arcanite, or archaically known as potash of sulfur) is a non-flammable white crystalline salt which is soluble in water, competitive prices. Potassium sulphate is commonly used in fertilizers, providing both potassium and sulfur.
1) Almost no chlorine, sodium and heavy metal .
2) Free liquidity, white crystal powder, soluble in water rapidly.
3) Aqueous solution show weakly acidic, can improve absorption of other cationic (especially trace elements).
4) Can meet the need of potassium of crops, lower salt-chemical index, applicable to all crops and all stages ,including flowering and maturity stages.
Potassium sulphate / SOP fertilizer 0-0-50 / 0-0-52
Quick-acting potash fertilizer Potassium sulfate is a high-component quick-acting potassium fertilizer. It is mainly prepared from sulfate minerals anhydrous potash and potassium chloride. It is white or light yellow crystalline particles, with α-type and β-type. Crystal form. The α-type is a colorless crystal of the hexagonal system, and the β-type is a colorless crystal of the orthorhombic system. It has a bitter and salty taste. Generally, it contains 90% to 95% potassium sulfate, 50% to 52% potassium (K2O), 16% sulfur (S), and less than 2.2% chlorine (Cl); in addition, there is a small amount of sodium (Na), calcium ( Ca), magnesium (Mg) and bromine (Br) Chemicalbook, etc. are insoluble in ethanol, acetone and carbon disulfide, easily soluble in water, and can be directly absorbed and utilized by plants. They can be used as base fertilizer, seed fertilizer and top dressing. Experiments have shown that applying 1 kilogram of potassium sulfate can increase the yield of grain crops by 6 to 8 kilograms and sugar beets by 15.5 to 22.5 kilograms. Some crops that are chlorine-averse (such as fruits, flax, tobacco, tea, citrus, potatoes, etc.) cannot be treated with potassium chloride, but potassium sulfate can be applied. When applying potassium sulfate to acidic soil, you need to add appropriate lime or mix it with phosphate rock fertilizer, which can improve the utilization rate of phosphorus without increasing soil acidity.
