Monopotassium Phosphate (MKP) 0-52-34 Potassium Fertilizer

Monopotassium phosphate (MKP) 0-52-34 supplies water-soluble potassium and phosphorus without adding nitrogen. Explore Haifa MKP and ICL PeaK MKP for hydroponic nutrient solutions, greenhouse production, and professional fertigation programs.

A nitrogen-free potassium source with phosphorus

MKP provides 34% soluble potash (K₂O) alongside 52% available phosphate (P₂O₅). For growers selecting fertilizers by potassium source, it is an option when the nutrient formula also requires phosphorus. Account for both nutrients when calculating application rates rather than treating MKP as a potassium-only fertilizer.

Choosing a potassium phosphate fertilizer

Potassium phosphate describes a family of salts, not one interchangeable fertilizer. Monopotassium phosphate, KH₂PO₄, is the specific form commonly abbreviated MKP. It differs from dipotassium phosphate in nutrient analysis and effects on solution pH. Match the chemical form and guaranteed analysis to your formulation.

MKP for hydroponics and fertigation

Fully water-soluble monopotassium phosphate can be incorporated into hydroponic nutrient solutions, drip fertigation programs, and soluble fertilizer blends. Its nitrogen-free analysis lets growers supply potassium and phosphorus while managing nitrogen separately through other ingredients.

Base application rates on your water analysis, crop requirements, and the other fertilizers in your program. Follow the selected product’s label and technical guidance for mixing and application.
