MKP Fertilizer 0-52-34
Monopotassium Phosphate
MKP Fertilizer for Fertigation, Agriculture & Fertilizer Production
Risso MKP Fertilizer 0-52-34 is a high-purity, fully water-soluble Monopotassium Phosphate (MKP) fertilizer supplying phosphorus and potassium in a concentrated nitrogen-free formulation.
What Is MKP Fertilizer?
MKP fertilizer, or Monopotassium Phosphate, is a highly water-soluble phosphorus and potassium fertilizer with the chemical formula KH₂PO₄.
The standard fertilizer grade is 0-52-34, meaning it contains approximately:- 0% Nitrogen (N)
- 52% Phosphate (P₂O₅)
- 34% Potash (K₂O)
Because MKP contains no nitrogen, it can be used when crops require additional phosphorus and potassium without increasing nitrogen input.
Its high nutrient concentration and water solubility make MKP 0-52-34 particularly suitable for precision fertilizer programs, including fertigation, greenhouse cultivation, hydroponics and foliar nutrition.

Important: MKP should be selected and applied according to crop nutrient requirements, soil or growing-medium conditions, irrigation water quality and the overall fertilizer program.
APPLICATION RATE
There is no universal application rate for MKP fertilizer. The rate should be based on crop needs, growth stage, soil or growing-medium conditions, and target P₂O₅ and K₂O supply.
For fertigation, consider irrigation water quality, fertilizer compatibility, EC, pH, and nutrient concentration.
Commercial application rates should follow crop requirements, local agronomic recommendations, and product specifications.

FREQUENTLY ASKED QUESTIONS
MKP fertilizer is Monopotassium Phosphate (KH₂PO₄), a water-soluble phosphorus and potassium fertilizer commonly sold as 0-52-34.
MKP 0-52-34 contains approximately 0% nitrogen, 52% P₂O₅ and 34% K₂O.
Yes. MKP is a highly water-soluble fertilizer and is widely used for fertigation, foliar application, hydroponics and water-soluble fertilizer production.
No. Standard MKP fertilizer has a 0-52-34 analysis and does not provide nitrogen.
MKP is primarily used to supply phosphorus and potassium in fertigation, greenhouse production, hydroponics, foliar nutrition, specialty crop production and fertilizer manufacturing.
Yes. MKP 0-52-34 is widely used in fertigation because of its high water solubility and concentrated P-K content.
Yes. MKP can be incorporated into hydroponic nutrient formulations where phosphorus and potassium need to be supplied without additional nitrogen.
Yes. MKP can be used for foliar application as a supplemental source of phosphorus and potassium. The application rate should be determined according to crop requirements and product recommendations.
MKP should generally not be mixed directly with concentrated calcium-containing fertilizers, including calcium nitrate, because phosphate and calcium can form insoluble precipitates. Separate stock tanks may be required in fertigation systems.
MKP can be used in fertilizer programs for greenhouse vegetables, fruit crops, vineyards, berries, field crops, flowers, ornamentals and hydroponic crops.
