Monopotassium Phosphate MKP 0-52-34
Premium agricultural Monopotassium Phosphate MKP 0-52-34: a nitrogen-free, concentrated phosphorus and potassium source
Ihumate Monopotassium Phosphate is a high-specification, fully water-soluble PK fertilizer raw material containing water-soluble phosphorus pentoxide > 52% and potassium oxide > 34%. Available as white crystals and white powder, this nitrogen-free input is designed for growth stages that require phosphorus and potassium while nitrogen must remain controlled. It suits fertigation, hydroponics, sprinklers, foliar feeding, water-soluble fertilizers and liquid fertilizer production.
1. Nitrogen-free P-K precision: useful during root establishment, flower induction, flowering, fruit set, sizing and ripening, while allowing agronomists to manage nitrogen independently.
2. High purity and rapid dissolution: controlled chloride, moisture and insoluble matter support clear nutrient solutions, lower emitter-blockage risk and reliable use in high-value crops and soilless systems.
3. Crystal and powder grades: crystals offer good flow and lower dust for handling and automated dosing; powder offers greater surface area and faster dispersion for rapid dissolution and fine blending.
4. The Ihumate advantage: every batch is checked for P2O5, K2O, moisture, chloride, pH, appearance and dissolution. Ihumate supports dependable supply, export documents, formulation guidance and 1-25 kg OEM/ODM packaging.
Compatibility: do not combine concentrated MKP stock with calcium or magnesium fertilizers because phosphate precipitates may form. Use separate A/B tanks or different application times. Iron, manganese, zinc and copper should be chelated, and every new tank mix should pass a jar test.

Frequently Asked Questions
1
Why is MKP 0-52-34 useful during flowering, fruit set and ripening?
MKP contains no nitrogen and supplies concentrated water-soluble phosphorus and potassium. Phosphorus supports energy transfer and reproductive development, while potassium contributes to sugar transport, water regulation and fruit-quality formation, allowing precise nutrition when excess nitrogen is undesirable.
2
What is the difference between crystal and powder MKP?
Both grades follow the same 0-52-34 nutrient specification. Crystals offer better flow and lower dust for storage and automated dosing, while powder disperses more quickly for rapid dissolution, foliar formulations and fine blending. Choose according to processing equipment and formulation needs.
3
Can MKP be used in fertigation, hydroponics and foliar spray?
Yes. High-purity, fully soluble MKP suits drip irrigation, hydroponics, sprinklers and validated foliar programs. Adjust rates to the crop, leaf age, water quality, target EC and local label, and test foliar applications on a small area first.
4
Can MKP share a concentrated stock tank with calcium nitrate or magnesium sulfate?
No concentrated mixing is recommended. Phosphate can react with calcium or magnesium and create precipitates that reduce nutrient availability and clog equipment. Use separate A/B tanks or separate application times.
5
Do the specifications printed in the packaging image apply to this product?
No. The packaging image only demonstrates Ihumate bag formats and OEM/ODM design capability. Final guaranteed analysis, net weight and regulatory text will follow the contract, batch COA and destination-market requirements.

Application & Dosage: Monopotassium Phosphate MKP 0-52-34
For fertigation, hydroponics, sprinklers, validated foliar feeding and production of high-phosphorus, high-potassium water-soluble, liquid and NPK fertilizers. The nitrogen-free analysis allows precise nitrogen control during flowering, fruit set, sizing and ripening. MKP is not a complete nutrition program; nitrogen, calcium, magnesium and micronutrients should follow soil, water and tissue analysis.
Agricultural Application
- Root and Reproductive Stages:Supply nitrogen-free P-K through fertigation or hydroponics during root establishment, pre-flowering, fruit set and quality development.
- Foliar P-K Supplement:Apply an even, low-concentration spray outside high heat and intense sunlight; test sensitive crops, new cultivars and new mixtures first.
Fertilizer Manufacturing
- Water-Soluble and Liquid Fertilizers:Use as a high-purity PK source for high-phosphorus, high-potassium, nitrogen-free and custom NPK formulas.
- Crystal or Powder Selection:Choose crystals for low-dust flow and handling, or powder for rapid dispersion and precision blending.
Application Ratio Scheme
| Crop Name | Growth Stage | Application Ratio |
|---|---|---|
| Fertigation/Hydroponics | Rooting, pre-flowering, fruit set or sizing | 3-8 kg/ha per application; adjust to analysis and formulation |
| Foliar Spray | Young leaves or sensitive crops | 0.5%-1.0%; conduct a crop-safety test first |
| Mature leaves and tolerant crops | 1.0%-2.0%; follow the local label | |
| Fertilizer Production | Water-soluble, liquid and NPK blending | Calculate from target P2O5 and K2O analysis |
