Products Description of Potassium Phosphate Monobasic CAS#7778-77-0
Potassium dihydrogen phosphate (chemical formula: KH₂PO₄) is a highly concentrated phosphorus-potassium compound fertilizer containing 52% P₂O₅ and 34% K₂O. It features low hygroscopicity, excellent physical properties, and high water solubility. At 20°C, 23 grams of the product can dissolve in 100 milliliters of water, forming an acidic aqueous solution. As an efficient, fast-dissolving phosphorus-potassium fertilizer, it supplies essential nutrients to support plant growth and development. It is suitable for all soil types and crops, particularly in areas with deficiencies in both phosphorus and potassium, as well as for crops with high requirements for these two essential nutrients.
