High-purity phosphate and potassium compounds designed specifically for rapid floral initiation, ovarian development, and stress-resilient fruit set.
From thermal-process phosphoric acid reaction to ultra-fine crystal screening, discover why our Monopotassium Phosphate delivers unmatched performance during anthesis and fruit development.
Formulated using high-purity crystalline chemistry that dissolves rapidly within seconds. Completely free from insoluble contaminants, ensuring zero clogging in high-pressure drip emitters, micro-sprinklers, and precision drone nozzles.
Supplies 52% P2O5 and 34% K2O with 0% Nitrogen. This critical ratio prevents excessive vegetative growth, tightens internodal spacing, and channels photosynthetic energy directly into reproductive floral sinks.
Free from chloride (Cl-), sodium (Na+), and heavy metal impurities. Features an exceptionally low electrical conductivity (EC) profile, safeguarding delicate flower petals and newly emerged fruitlets from chemical scorching.
During the critical transition from vegetative growth to reproductive development, plant physiology demands an abrupt shift in cellular energetics and carbohydrate allocation. Monopotassium Phosphate (KH2PO4), commonly referred to as MKP 0-52-34, represents the most bioavailable, fully soluble source of primary phosphorus and potassium for commercial agriculture.
Phosphorus (52% P2O5) acts as the essential structural backbone of adenosine triphosphate (ATP) and nucleic acids. In the pre-bloom and blooming phases, vigorous cellular division takes place within the floral meristem. Ample bioavailable phosphorus accelerates flower bud differentiation, increases the total number of viable blossoms, fortifies pollen tube elongation, and significantly extends ovule longevity, thereby maximizing the window for effective pollination.
Simultaneously, Potassium (34% K2O) governs stomatal conductance, osmotic equilibrium, and the enzymatic activation required for sucrose translocation. Upon successful fertilization, the newly formed fruitlet transitions into a high-demand carbohydrate sink. Potassium activates transport enzymes that shuttle photoassimilates from source leaves directly to developing fruit ovaries, preventing premature fruitlet abscission (drop) and initiating uniform cell division.
The global market for specialty water-soluble fertilizers has witnessed a structural shift toward high-efficiency, targeted nutrient delivery systems. Intensive horticulture, indoor vertical farming, substrate hydroponics, and precision UAV aerial spraying are replacing legacy broadcast fertilization methods. As a premier monopotassium phosphate manufacturer, Sichuan Luobu New Material Technology Co., Ltd. sits at the heart of this technological transformation.
Situated in Shifang City, Sichuan Province—China's world-renowned phosphate chemical corridor—our manufacturing infrastructure benefits from direct access to high-grade mineral reserves and fully integrated thermal phosphoric acid processing lines. This industrial foundation guarantees steady supply chain stability, tight control over raw chemical inputs, and consistent lot-to-lot crystallization purity.
Commercial agronomists and fertilizer distributors worldwide increasingly mandate stringent purity thresholds. Our manufacturing process specifically eliminates unreacted orthophosphates, organic residues, and heavy metals, yielding a technical-grade crystal that complies with strict global agricultural standards across the Americas, Europe, the Middle East, and Southeast Asia.
Strategic application schedules designed to optimize reproductive yields across orchards, fruiting vegetables, and intensive greenhouse operations.

Luobu holds multiple invention and utility model patents related to fertilizer formulation and application technology. The company has been recognized in China as a National High-Tech Enterprise and has received several provincial-level innovation awards.
In 2023, its flagship Drone-Grade MKP was officially included in the “Top 100 Major Agricultural Science and Technology Achievements” by the Chinese Academy of Agricultural Sciences, underscoring our technological leadership in ultra-efficient foliar delivery systems.
The company operates its own manufacturing facility, equipped with standardized production lines and internal quality control procedures. From raw material sourcing to finished product packaging, each stage follows established operating standards to ensure product consistency and traceability.
Particular attention is given to dissolution rate, insoluble residue control, particle distribution, and moisture stability—factors that are critical in both drone spraying systems and irrigation-based applications. In addition to Drone-Grade MKP, Luobu also manufactures conventional crystalline MKP, monoammonium phosphate (MAP), and a comprehensive portfolio of water-soluble nutrients.
Engineered specifically for agricultural drone spraying systems to achieve flawless atomization and rapid foliar absorption during peak reproductive stress.
Drone-Grade MKP dissolves completely in cold water within 30 seconds without secondary stirring. Its instant-solubility matrix eliminates nozzle sedimentation in ultra-concentrated drone tanks.
Conventional fertilizers designed for ground fertigation often suffer from micro-particulate residue. Our drone-optimized MKP features strict particle distribution control, guaranteeing 100% spray uniformity.
Delivers rapid phosphorus-potassium systemic absorption via leaf stomata, boosting cellular turgor and enzymatic stress-defense pathways when heatwaves threaten floral pollination.

Monopotassium Phosphate provides a concentrated source of phosphorus and potassium with zero nitrogen. High nitrogen levels during bloom induce aggressive shoot extension, leading to floral abortion and reduced fruit set. MKP checks this vegetative vigor, fostering strong reproductive sink strength.
