    Monopotassium Phosphate (MKP) | High-Purity Potassium Dihydrogen Phosphate

    Monopotassium Phosphate (MKP), also known as Potassium Dihydrogen Phosphate, is a highly soluble source of phosphorus and potassium widely used in agriculture, horticulture, fertigation, and specialty fertilizer production. It provides two essential plant nutrients without adding nitrogen or chloride.

    MKP is typically supplied as a white crystalline powder or granules with excellent water solubility. Its high nutrient concentration makes it suitable for water-soluble fertilizer blends and applications where precise nutrient management is required.

    MKP Fertilizer Applications

    Monopotassium Phosphate fertilizer is widely used for crops requiring phosphorus and potassium without additional nitrogen. It can be applied through fertigation, foliar feeding, hydroponic systems, and other controlled fertilizer programs where the product grade is appropriate.

    MKP is suitable for various agricultural and horticultural crops, including fruits, vegetables, flowers, ornamental plants, and specialty crops.

    Key Benefits of Monopotassium Phosphate

    MKP provides a concentrated combination of phosphorus and potassium. Phosphorus supports important processes related to energy transfer and root development. Meanwhile, potassium contributes to water regulation, enzyme activity, nutrient transport, and overall plant growth.

    Because MKP contains no nitrogen, it can be incorporated into fertilizer programs where nitrogen application needs to be controlled. Furthermore, its high water solubility makes it convenient for many water-soluble fertilizer applications.

    Industrial and Specialty Applications

    Beyond agricultural use, Potassium Dihydrogen Phosphate is used in selected industrial, laboratory, food-related, and technical applications, depending on the product grade and applicable regulations.

    The appropriate grade should be selected according to the intended application. Buyers should review the technical specification, COA, and SDS before purchase and use.

    Packaging and Wholesale Supply

    Monopotassium Phosphate can be supplied in 25 kg bags, 50 kg bags, jumbo bags, or bulk packaging. Packaging can be selected according to order quantity, transportation requirements, and destination.

    We offer Monopotassium Phosphate wholesale and bulk supply for international B2B buyers. Customers can request product specifications, COA, SDS, packaging information, origin, loading quantities, and commercial quotations.

    Potassium dihydrogen phosphate is a potassium salt in which dihydrogen phosphate(1-) is the counterion. It has a role as a fertilizer. It is a potassium salt and an inorganic phosphate.|Monopotassium phosphate, MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate), KH2PO4, is a soluble salt of potassium and the dihydrogen phosphate ion. It is a source of phosphorus and potassium as well as a buffering agent. It can be used in fertilizer mixtures to reduce escape of ammonia by keeping pH low.
