In the production of water-soluble fertilizers, liquid fertilizers, and phosphorus-potassium fertilizers, both potassium hydroxide (KOH) and potassium carbonate (K₂CO₃) can serve as potassium sources. Since neither compound is based on chloride as its principal anion, both are commonly considered for fertilizer systems designed for chloride-sensitive crops or applications where chloride content needs to be controlled. However, when viewed as fertilizer raw materials, rather t

Potassium hydroxide, with the chemical formula KOH, is also known as caustic potash. It is an inorganic compound characterized by strong alkalinity, high water solubility, and high chemical reactivity. Among its various commercial forms, 90% potassium hydroxide flakes are widely used due to their high active content and convenient storage and transportation.
