High-purity Monopotassium Phosphate (MKP) engineered for zero-clog drip irrigation and fertigation systems — factory direct from China's leading phosphate production hub.
Monopotassium Phosphate (KH₂PO₄) is the preferred phosphorus-potassium source for modern drip irrigation and fertigation due to its unique physicochemical properties and agronomic performance.
Ultra-high purity MKP dissolves completely in water with no insoluble residues, eliminating emitter clogging in drip lines, micro-sprinklers, and fertigation injectors.
Engineered spray-dried particle structure ensures fast, uniform dissolution even in cold water, maintaining consistent nutrient concentration throughout the irrigation cycle.
Delivers 52% P₂O₅ and 34% K₂O in a single compound, supporting root development, flowering, fruit setting, and stress resistance without nitrogen interference.
MKP naturally acidifies irrigation water, preventing calcium and magnesium carbonate precipitation inside drip lines, extending system lifespan significantly.
Fully compatible with drip tape, subsurface drip, micro-sprinkler, and pivot fertigation systems across greenhouse, open-field, and hydroponic applications.
ISO 9001 quality management, multiple invention patents, and membership in China's leading phosphate industry associations ensure consistent, verified product quality.
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 specialization in water-soluble MKP products optimized for drip irrigation, fertigation, and precision agricultural delivery systems.

+86 13219891661The global Monopotassium Phosphate market is experiencing robust growth driven by the rapid adoption of precision irrigation technologies, water scarcity challenges, and the intensification of high-value crop production worldwide.
The global drip irrigation market is projected to exceed USD 12 billion by 2030, growing at a CAGR of over 9%. As drip systems proliferate across arid regions in the Middle East, India, Africa, and Latin America, demand for fully water-soluble fertilizers like MKP is surging in parallel, making reliable MKP suppliers increasingly critical to the supply chain.
Fertigation — the injection of fertilizers through irrigation systems — is rapidly replacing broadcast and foliar application in commercial horticulture, greenhouse production, and row crop farming. MKP's complete water solubility, neutral-to-slightly-acidic pH, and chloride-free formulation make it the top-choice phosphorus-potassium source for fertigation programs globally.
China accounts for over 60% of global MKP production capacity, with Sichuan Province being a key production hub due to abundant phosphate rock reserves. Chinese MKP suppliers have significantly improved product purity to 99%+, meeting international standards for drip irrigation and hydroponic applications, while maintaining competitive pricing that drives global sourcing decisions.
The convergence of IoT-enabled irrigation controllers, soil sensors, and automated fertigation systems is creating demand for highly consistent, ultra-pure MKP that performs predictably in automated dosing equipment. Suppliers capable of delivering pharmaceutical-grade consistency at agricultural scale are commanding premium market positions in this fast-evolving segment.
From greenhouse hydroponics to large-scale field crop fertigation, MKP delivers precision phosphorus and potassium nutrition across the most demanding drip irrigation environments.

Beyond drip lines, MKP's ultra-fine particle size and complete solubility make it the ideal complement to UAV (drone) foliar nutrition programs, delivering synchronized soil and canopy phosphorus-potassium nutrition for maximum crop response.
In closed-loop hydroponic drip systems for tomatoes, cucumbers, peppers, and leafy greens, MKP is a cornerstone of nutrient solution formulation. Its chloride-free, sodium-free profile prevents ion toxicity, while its acidifying effect helps maintain optimal pH (5.5–6.5) in recirculating systems. Suppliers providing consistent EC-neutral MKP batches are preferred by large greenhouse operators.
For corn, wheat, cotton, and soybean production under subsurface drip irrigation (SDI), MKP is applied during critical phosphorus demand windows — early vegetative growth, pre-flowering, and grain fill. Compared to MAP or DAP, MKP delivers simultaneous potassium without requiring a separate K source, reducing fertigation program complexity and injection equipment wear.
Vineyards, citrus orchards, avocado farms, and berry operations rely on MKP fertigation during flowering and fruit development stages to boost sugar content, fruit firmness, and shelf life. The potassium component activates over 60 plant enzymes involved in photosynthesis and sugar transport, while phosphorus supports energy transfer during rapid cell division periods.
Large-scale commercial farming operations and irrigation districts are increasingly investing in automated fertigation infrastructure with inline EC/pH monitoring, proportional injectors, and real-time nutrient management software. For these systems, MKP supplier consistency — batch-to-batch purity, particle size uniformity, and dissolution rate stability — directly impacts system calibration accuracy and crop nutrition outcomes.
