Luobu’s drone-grade MKP Certified in 2024 National Patent-Intensive Products List
On February 8, 2025, the China Patent Protection Association released the 2024 Annual PatentIntensive Products List, Luobu’s drone‑grade monopotassium phosphate (MKP) has been officially awarded the Patent-Intensive Product Certification.
A patent-intensive product gains its competitive strength mainly from its patents.
As the first mover of drone-grade MKP, Sichuan Luobu created an entirely new product category for drone-grade MKP.
It owns a total of 8 patents for its drone-grade MKP.
Through continuous R&D and innovation,
Sichuan Luobu has upgraded its drone-grade MKP to the third generation.
All this fully demonstrates our strong market advantage and competitiveness in the MKP sector.
It is reported that since Sichuan Luobu pioneered in drone-grade MKP,the company has greatly driven innovation and development across the entire MKP industry.
In addition，on January 9, 2025, Sichuan Luobu--headquartered in Shifang, one of China’s four major phosphate ore bases--hosted the 2025 Drone-Grade MKP Technology Innovation & Upgrade Seminar, where the company officially launched its third-generation drone-grade MKP.
At the seminar the company also officially launched the Luobu Phosphate & Potassium Innovation Fund，with a commitment to invest 100 million yuan over the next decade dedicated to product R&D and innovation.
The third-generation drone-grade MKP from Sichuan Luobu marks a major technological breakthrough for MKP products, with key advancements in the following areas:
1. Excellent moisture resistance and superior anti-caking performance.Under normal storage conditions, the product remains stable for more than two years without caking.
2. Improved flowability.With synergists, the product has a smaller angle of repose, making it smoother and more flowable.
3. Smaller contact angle, better wettability.After adding synergists, the product has a contact angle of less than 69° on leaf surfaces, enabling stronger adhesion and improved wetting.
4. Lower surface tension.The product solution delivers a surface tension of below 30 mN/m, after adding synergistsclose to the critical wetting threshold of plant leaf surfaces (approximately 25 mN/m) so the solution can penetrate directly into the epidermis through stomata, boosting nutrient uptake and enhancing fertilizer efficiency.
5. Fast dissolution rate. Mild foaming at the beginning of dissolution is a normal result of the synergists, which improves spreading and penetration on leaves and also helps reduce drift in drone applications.
6. Strong tank-mix compatibility.As a value-added product developed on the basis of original drone-grade MKP, it features excellent tank-mix compatibility and can be mixed and applied on site with a broader range of pesticides and fertilizers.The built-in synergists also improve the efficacy of pesticides.
In short: excellent adhesion, small contact angle, anti-caking, high absorption, and strong compatibility.
Most importantly, the board of directors of Sichuan Luobu has made a clear decision: the third-generation drone-grade MKP – enhanced performance at no extra cost! As a value-added product, it is offered at the same price as our original drone-grade MKP. We provide greater value without raising the price. It delivers better performance, improves effective absorption and utilization, saves farmers’ efforts,boosts their yields and helps our customers earn more.
