Acidic Potassium Phosphate (AKP) is a highly concentrated, fully water-soluble phosphorus and potassium fertilizer with an NPK analysis of 0-60-20. Chemically, AKP is commonly represented as KH₅(PO₄)₂, also known as potassium pentahydrogen bis (phosphate). It may also be described as an acidic phosphate system derived from approximately equimolar monopotassium phosphate (KH₂PO₄) and phosphoric acid (H₃PO₄). Its molecular weight is approximately 234.08 g/mol. Unlike convention
