Our core product line is specifically formulated for drip and sprinkler fertigation systems in greenhouse environments — delivering precise nutrition with zero clogging.
Years Experience
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 greenhouse fertigation systems, precision drip irrigation, and UAV foliar nutrition solutions.

+86 13219891661China has emerged as the world's dominant supplier of Monopotassium Phosphate (MKP) for greenhouse fertigation systems. Backed by abundant phosphate reserves, advanced manufacturing infrastructure, and a rapidly expanding precision agriculture sector, Chinese MKP producers now account for over 65% of global export volume.
China's Sichuan, Yunnan, and Guizhou provinces form the core of its phosphate-chemical industrial belt. State-of-the-art spray-drying towers, automated crystallization lines, and ISO-certified quality systems enable Chinese MKP suppliers to deliver pharmaceutical-grade purity (≥99.0% MKP) at competitive global pricing — a critical requirement for clog-free greenhouse fertigation emitters.
Chinese MKP suppliers export to over 80 countries, serving greenhouse operators across Europe, the Middle East, Southeast Asia, and Latin America. The global greenhouse fertigation market is projected to surpass USD 8.5 billion by 2030, driven by water scarcity concerns and the accelerating shift toward soilless cultivation, hydroponics, and vertical farming — all of which rely heavily on high-purity MKP as a primary phosphorus-potassium source.
Leading Chinese MKP manufacturers invest significantly in R&D, developing specialized formulations such as drone-spraying grade MKP, ultra-low-chloride crystal MKP for sensitive crops, and fully chelated micronutrient-enhanced NPK blends. These innovations directly address the evolving demands of smart greenhouse controllers, EC/pH dosing systems, and automated fertigation scheduling platforms.
Modern greenhouse operators increasingly demand MKP that is fully compatible with IoT-driven fertigation controllers. Chinese suppliers are developing ultra-fine crystal grades with dissolution rates under 60 seconds at 20°C, enabling real-time nutrient dosing without sensor fouling or pipe blockage in automated drip and NFT systems.
Environmental compliance is reshaping China's fertilizer sector. Manufacturers are adopting closed-loop wastewater recycling, low-emission spray-drying processes, and phosphogypsum valorization technologies. Eco-certified MKP products now carry EU REACH compliance and OMRI-listed organic certifications, opening premium greenhouse markets in Europe and North America.
The global vertical farming market is growing at 25%+ CAGR, creating surging demand for food-grade MKP in hydroponic nutrient solutions. Chinese suppliers are scaling up pharmaceutical-grade production lines to serve this premium segment, with chloride content below 50ppm and heavy metal specifications meeting EU food safety standards.
One-size-fits-all fertilizers are giving way to crop-specific, stage-specific fertigation programs. Chinese MKP suppliers now offer OEM blending services — combining MKP 0-52-34 with MAP, KNO₃, and chelated micronutrients to create tailor-made A+B nutrient concentrates for tomato, cucumber, pepper, strawberry, and cannabis greenhouse production.
From high-wire tomato production to strawberry substrate cultivation, MKP plays a critical role across diverse greenhouse fertigation scenarios. Explore how our products deliver measurable results.
Monopotassium Phosphate (MKP, 0-52-34) is uniquely positioned as the cornerstone nutrient in greenhouse fertigation programs for several scientifically grounded reasons. With a nitrogen-free formula, it allows growers to independently manage phosphorus and potassium inputs without disturbing the N-P-K balance — essential during flowering, fruit development, and root establishment phases.
In closed-loop recirculating systems such as NFT (Nutrient Film Technique) and DWC (Deep Water Culture), MKP's near-neutral pH contribution (pH 4.4–4.7 in solution) helps buffer the nutrient solution and prevent alkalinity buildup that causes calcium and magnesium precipitation. This property is indispensable for maintaining emitter performance in long-run drip tapes and micro-jet irrigation systems.
Furthermore, high-purity Chinese MKP (≥99% assay) dissolves completely without residue, ensuring EC meter accuracy and preventing the formation of insoluble phosphate salts that foul filters and drip emitters. For greenhouse operators running 16-hour fertigation cycles with sub-second dosing precision, this level of purity is non-negotiable.
As a council member of the China Agricultural Technology Extension and Service Association, Luobu pioneered drone-spraying grade MKP — a technology now adopted across 60+ countries. Our patented centrifugal spray-drying tower produces ultra-fine, free-flowing crystals optimized for both UAV nozzles and greenhouse fertigation injectors.
Our MKP 0-52-34 achieves ≥99.0% assay with chloride content below 200ppm, heavy metals below EU food-grade thresholds, and water insoluble matter below 0.05%. Each production batch undergoes third-party SGS/BV verification — providing greenhouse operators with the traceability documentation required by EU, USDA, and GLOBALG.A.P. certification bodies.
Engineered for fertigation compatibility, our crystal MKP dissolves completely in under 90 seconds at 15°C — far exceeding industry standard specifications. This eliminates filter blockages, maintains consistent EC readings in automated dosing systems, and reduces maintenance downtime for large-scale commercial greenhouse operations.
Our agronomic team provides customized fertigation program design using MKP as the phosphorus-potassium backbone, integrated with MAP, KNO₃, calcium nitrate, and chelated micronutrients. Programs are available for tomato, pepper, cucumber, lettuce, strawberry, cannabis, and cut flower greenhouse production systems.
With direct access to Chengdu-Europe railway freight and major Chinese seaports, we offer FOB, CIF, and DDP delivery options. Standard lead time is 15–25 days for 20FCL orders. Our packaging options include 25kg moisture-proof bags, 500kg jumbo bags, and custom OEM packaging for distributor branding requirements.
Luobu holds ISO 9001 Quality Management System certification, multiple invention patents for eco-friendly fertilizer formulations and spray-drying technology, and is recognized as a Patent-Intensive Product manufacturer by China's national IP authority. Our products meet EU REACH, China GB standards, and international fertigation grade specifications.
