High-Purity 99% MKP — Chloride-Free Fast Dissolving Solution for Fertigation Programs
Monopotassium Phosphate (MKP, KH₂PO₄) with the formula 0-52-34 is one of the most efficient water-soluble fertilizers available for fertigation programs. Its exceptionally high purity (≥99%), complete water solubility, and fast-dissolving crystal structure make it the preferred phosphorus-potassium source for drip irrigation, hydroponic systems, and precision fertigation operations worldwide.
💡 Fast Dissolving MKP dissolves completely within seconds at standard fertigation temperatures, ensuring zero clogging in drip emitters, filters, and injection lines — a critical advantage over conventional granular fertilizers.
Unlike compound fertilizers that may leave residues or cause pH instability, MKP carries a slightly acidic reaction (pH ~4.5 in solution), which helps prevent calcium and magnesium precipitation in irrigation water, keeping fertigation lines clean and nutrient delivery consistent across every irrigation cycle.
With a phosphorus content of 52% P₂O₅ and potassium content of 34% K₂O, MKP delivers two critical macronutrients simultaneously — supporting root development, flowering, fruit set, and stress resistance throughout the crop's growth cycle.
Engineered for the demands of precision agriculture — from greenhouse hydroponics to large-scale open-field drip fertigation.
Specially processed crystal structure ensures complete dissolution in seconds, even in cold water conditions — critical for automated fertigation injectors and dosing systems.
Pharmaceutical-grade purity with minimal impurities, ensuring no clogging of micro-drip emitters, no scale buildup in pipes, and consistent nutrient concentration across every batch.
Zero insoluble residue. Compatible with all fertigation hardware including venturi injectors, dosatron systems, and EC/pH-controlled nutrient dosing stations.
Completely free of chloride ions — safe for chloride-sensitive crops including strawberries, tomatoes, lettuce, and high-value horticultural produce in fertigation systems.
MKP solution has a natural pH of ~4.5, helping neutralize alkaline irrigation water and preventing nutrient lock-out — especially important in calcareous soil fertigation programs.
Mixes seamlessly with calcium nitrate, magnesium sulfate, and micronutrient concentrates in multi-tank fertigation systems without precipitation or chemical interaction.
The global fertigation market is expanding rapidly, driven by water scarcity, precision agriculture adoption, and the growing demand for high-quality produce.
Global drip irrigation area surpassed 17 million hectares in 2024 and is projected to reach 26 million hectares by 2030. Every new drip system represents a direct demand for fast-dissolving, fully water-soluble fertilizers like MKP — making fertigation-grade MKP one of the fastest-growing specialty fertilizer segments globally.
Controlled Environment Agriculture (CEA) and hydroponic production are growing at 12–15% annually worldwide. Fast dissolving MKP is a foundational component of virtually all hydroponic nutrient solutions, particularly during the phosphorus-intensive vegetative and early flowering stages, creating sustained commercial demand.
Smart fertigation systems with EC/pH sensors, automated dosing, and real-time monitoring are being deployed at scale across Europe, North America, and Asia-Pacific. These systems require fertilizers with guaranteed purity and solubility specifications — elevating the standard for MKP quality in commercial fertigation programs.
China produces over 60% of the world's MKP supply, with Sichuan Province — home to abundant phosphate rock reserves — emerging as the premier production hub. Chinese manufacturers are rapidly upgrading to food/agricultural-grade and drone/fertigation-grade MKP to meet the quality demands of international buyers across 60+ countries.
From small greenhouse operations to large-scale commercial farms, MKP is integrated into fertigation programs at multiple critical growth stages and delivery methods.
In large-scale wheat, corn, and cotton production, fast dissolving MKP is injected through drip tapes during the tillering, jointing, and grain-filling stages. Its rapid dissolution ensures uniform nutrient distribution across thousands of meters of drip line without concentration gradients or emitter blockage.
MKP is a primary phosphorus-potassium source in hydroponic nutrient recipes for tomatoes, cucumbers, peppers, and leafy greens. Its neutral-to-acidic reaction in solution helps maintain the ideal pH range (5.5–6.5) in recirculating hydroponic systems, reducing the need for additional pH-down products.
In coco coir, perlite, and rockwool substrate systems, MKP delivers phosphorus and potassium without competing ions. Its chloride-free, sulfate-free profile makes it ideal for substrate fertigation where ion balance is critical for preventing osmotic stress and nutrient antagonism.
During fruit set and sizing stages, MKP is applied via drip or micro-sprinkler fertigation to boost potassium translocation to developing fruits, improving sugar content (Brix), skin firmness, color development, and post-harvest shelf life — key quality parameters for export markets.
In two-tank or three-tank fertigation systems, MKP is typically placed in the phosphorus-potassium tank (Tank B), separate from calcium nitrate (Tank A) to prevent calcium phosphate precipitation. Its fast dissolution allows rapid stock solution preparation at high concentrations (up to 300 g/L).
Drone-grade fast dissolving MKP is formulated specifically for agricultural UAV spray systems, where ultra-fine droplet generation requires fertilizers with zero undissolved particles. Luobu's spray-drying technology produces MKP crystals with optimized particle size distribution for instant dissolution in drone spray tanks.
Sichuan Luobu New Material Technology Co., Ltd., founded in 2019, is located in Shifang City, Sichuan Province — one of China's key phosphate production regions. The area is known for its strong phosphate resource base and well-developed industrial infrastructure, providing a solid foundation for fertilizer manufacturing and technical innovation.
The company focuses on the research, production, and supply of high-performance phosphate-based fertilizers for modern agriculture, with a particular specialization in fast-dissolving MKP products engineered for fertigation programs, hydroponic systems, and agricultural UAV spraying applications.
