INTRODUCTION Monopotassium phosphate fertilizers are high-purity, fully water-soluble fertilizers that supply phosphorus (P) and potassium (K) in readily available forms. Chemically known as KH₂PO₄, monopotassium phosphate (MKP) is widely used in fertigation, foliar feeding, and hydroponic systems due to its high solubility, chloride-free composition, and low salt index. Understanding the compositions of monopotassium phosphate fertilizers […]
