Explore the advanced world of Mono Potassium Phosphate (MKP)—from production process and technical indicators to global application cases, product advantages, and customized solutions. A data-driven guide to monopotassium phosphate and mkp fertilizer for progressive industries.
Industry Trends of Mono Potassium Phosphate (MKP)
As a leading water-soluble phosphate fertilizer, mono potassium phosphate is increasingly pivotal in modern agriculture, specialty chemicals, and water treatment. Global demand for MKP fertilizer has exhibited a CAGR of 5.6% (2021-2024, source) owing to its unrivaled purity, high NPK value (0-52-34), and eco-friendly characteristics.
Rising adoption in precision agriculture and fertigation systems
Growing popularity in seed coating & foliar application
Emergence in non-agricultural sectors: fire retardants, ceramics, electronics
Stringent demands for ISO-compliant, food & pharma grade monopotassium phosphate
* Conforming to ISO 9001, REACH, and FDA food safety standards where applicable.
Manufacturing Process of Mono Potassium Phosphate
The typical manufacturing process of mono potassium phosphate involves high-purity raw materials, rigorous controls, and advanced technology to ensure optimum quality for agrochemical and industrial uses.
Raw Materials: Food/pharma grade phosphoric acid (H3PO4), high-purity potassium carbonate (K2CO3) or potassium hydroxide (KOH)
Reaction: Conducted under controlled temperature (80–120°C) for optimum conversion
Filtration/Purification: Removal of insoluble matter and color-imparting impurities
Crystallization: Slow cooling for optimal crystal formation and flowability
Final Product: High purity mono potassium phosphate (MKP, KH2PO4)
The production is strictly governed by ISO 9001, REACH, and SGS inspection protocols, ensuring each batch of MKP fertilizer meets the highest global standards (ISO/TC 134: Fertilizers and soil conditioners).

The micro-granular, free-flowing nature and high solubility of mono potassium phosphate make it suitable for modern fertigation and hydroponics.
Uniform granule size: 0.1–0.3 mm
No caking, fast-dissolving
Innovative packaging with anti-moisture laminates
Product Comparison: MKP vs. Other Phosphate Fertilizers
MKP stands out with its balanced potassium (34%) and phosphorus (52%) and zero nitrogen, making it ideal for chloride-sensitive crops, precision nutrition, and as base for fertilizer customization.
Application Sectors of Monopotassium Phosphate
Fertigation/Drip irrigation: Enhances yield & root development (62%)
Fire Retardants: As ingredient in fire extinguishing powders (7%)
Ceramic/Electroplating: Flux and buffer functions (6%)
Feed Additives: Mineral nutrition for livestock (5%)
Key Technical Advantages of Mono Potassium Phosphate
Purity & Solubility: Water solubility up to 230g/L @ 20°C (no precipitation), ensures total uptake via fertigation.
Material: Ultra-fine crystal structure, free from chloride, sodium, and heavy metals.
Flexibility: Non-hygroscopic, free-flowing, easy integration with other NPKs and micronutrients.
Corrosion Inhibition: Phosphate ions act as safe corrosion inhibitors for water networks (meets NSF/ANSI Standard 60 requirements).
Energy-Saving: Efficient conversion reduces energy input by 8% compared to conventional triple superphosphate.
Industrial Case: Steel Pipe Company, Hebei, China
In 2022, a major steel pipe factory adopted mono potassium phosphate as anti-scaling agent. Their cooling water circuits displayed a 39% decrease in calcium deposits (ISO 9227:2017), enhancing pipe lifespan by 18% and reducing energy use for cleaning maintenance.
MKP fertilizer was integrated into a drip fertigation schedule, raising average fruit set by 16% compared to MAP baseline, and reducing total fertilizer salt index by 19%.

1. What is the chemical structure of mono potassium phosphate?
Mono potassium phosphate (KH2PO4) is a compound of potassium cation (K+) and dihydrogen phosphate anion (H2PO4-).
2. What are the main mkp fertilizer uses in agriculture?
As a source of highly plant-available phosphorus and potassium, MKP is widely applied for root growth, fruiting, flower development, and as a foliar feed for crops requiring chloride-free nutrition.
3. How do you ensure MKP product quality?
FIZA Chemical follows ISO 9001:2015 quality systems, multi-parameter batch testing (ICP-MS, titrimetric, UV-Vis), and third-party inspection with COA traceability for every lot.
4. What are the packaging options and shelf life?
Standard is 25kg/50kg/1000kg moisture-resistant bags; shelf life is 2 years under recommended storage.
5. Is MKP fertilizer suitable for organic farming?
Certain grades are suitable for organic farming and comply with NOP standards (subject to certification).
6. What installation standards should be followed for industrial use?
When using MKP in water treatment or industrial dosing, refer to ANSI/ASAE S318.17 and local health & safety protocols for chemical integration.
7. Can mono potassium phosphate be blended with other products?
Yes, MKP is compatible with most NPK fertilizers except calcium/magnesium-based solutions to prevent reactant precipitation.
