Monopotassium Phosphate (MKP) 0-52-34 Fertilizer

Monopotassium phosphate (MKP) 0-52-34 is a fully water-soluble, nitrogen-free fertilizer that supplies phosphorus and potassium for professional crop nutrition. Custom Hydro Nutrients carries Haifa MKP and ICL PeaK MKP for hydroponic nutrient solutions, greenhouse production, and fertigation programs.

With an analysis of 0-52-34, monopotassium phosphate provides 52% available phosphate (P₂O₅) and 34% soluble potash (K₂O). This concentrated phosphorus and potassium source lets growers adjust both nutrients without adding nitrogen.

Potassium phosphate fertilizer: choosing the right form

Potassium phosphate is a broader term that includes different phosphate salts. Monopotassium phosphate identifies the specific MKP form, KH₂PO₄. It is not interchangeable with dipotassium phosphate, which has a different nutrient analysis and different effects on solution pH. Check the chemical name and guaranteed analysis when selecting a product for your nutrient formula.

MKP for hydroponics and fertigation

Monopotassium phosphate is used in hydroponic nutrient solutions, drip fertigation, and water-soluble fertilizer blends. Its nitrogen-free analysis provides flexibility when balancing phosphorus and potassium against nitrogen supplied by other fertilizers.

Select application rates based on your crop, growth stage, water analysis, and complete nutrient program. Follow the selected product’s label and technical instructions for mixing and application.
