Launches Third-Generation Drone-Grade Monopotassium Phosphate
Shifang, Sichuan — November 14, 2025 — Sichuan Luobu New Materials Technology Co., Ltd., a specialized manufacturer of drone-optimized monopotassium phosphate (MKP), announced today that it has achieved RMB 450 million in annual revenue, reflecting strong market adoption of its proprietary Drone-Grade MKP fertilizer designed for agricultural UAV spraying systems.
The milestone coincides with the company’s sixth anniversary and the commercial launch of its third-generation Drone-Grade Monopotassium Phosphate, marking another step in Luobu’s focused strategy on precision-application fertilizers.
Engineered for Real-World Drone Operations
Unlike conventional crystalline MKP products originally designed for irrigation systems, Luobu’s Drone-Grade MKP is formulated specifically for high-concentration aerial spraying environments.
The newly released third-generation formulation introduces three major upgrades:
- 24-month anti-caking stability, reducing storage risks in humid and tropical climates
- Improved tank-mix compatibility, allowing co-application with a broader spectrum of crop protection products and micronutrients
- Lower surface tension and optimized wetting performance, enhancing leaf adhesion and phosphorus–potassium uptake efficiency
According to field feedback from large-scale growers and drone service providers, dissolution speed and spray consistency directly affect operational cost and equipment longevity. The upgraded MKP formulation was developed to address those practical challenges rather than compete solely on nutrient content.

Intellectual Property and Industry Recognition
Luobu’s Drone-Grade MKP portfolio is supported by 4 invention patents and 9 utility model patents, including eight patents related to flash-dissolution processes and formulation optimization tailored for drone spraying systems.
The product has been recognized as a National Patent-Intensive Product by the China Patent Protection Association and was included in China’s Top 100 Major Agricultural Science and Technology Achievements (2023).
These recognitions reflect the company’s emphasis on application-driven R&D within the broader water-soluble phosphate fertilizer sector.
Fourth-Generation Development Underway
Luobu confirmed that a fourth-generation Drone-Grade MKP is currently in development. The research focuses on improving phosphorus compatibility with calcium, zinc, iron, and aluminum — a long-standing formulation challenge in water-soluble fertilizers.
Phosphorus fixation in soil remains a key constraint in high-yield cropping systems. By enhancing compatibility and reducing antagonistic reactions, the new technology aims to improve same-season nutrient uptake efficiency under both drone spraying and fertigation systems.
Strategic Discipline: “Go Deep, Not Wide”
Since 2022, Sichuan Luobu has maintained a deliberate strategic focus on drone-grade and precision-application monopotassium phosphate, avoiding expansion into unrelated fertilizer categories.
“We chose to go deep rather than diversify broadly,” said Zhang Xuan, Chairman of Sichuan Luobu. “In a market where price competition is common, we believe long-term competitiveness comes from solving application-level problems.”
This focus has positioned Luobu as a specialized MKP manufacturer for agricultural drone systems, rather than a general fertilizer trader.
Expansion in Talent and Research Infrastructure
Between 2022 and 2025, the company expanded from 70 to more than 170 employees, including seven postgraduate researchers. In parallel, Luobu established long-term R&D collaborations with:
- Peking University
- China Agricultural University
- Sichuan University
- Sichuan Agricultural University
- Shandong Agricultural University
- Gansu Agricultural University
- Sichuan University of Science & Engineering
The partnerships are supported by a 10-year, RMB 100 million innovation investment plan dedicated to phosphorus–potassium efficiency enhancement and formulation science.
