Our flagship foliar-grade water soluble NPK fertilizers — precisely formulated for aerial spraying, drip irrigation, and high-efficiency crop nutrition programs.
Water soluble NPK fertilizers are fully dissolvable compound fertilizers containing nitrogen (N), phosphorus (P), and potassium (K) in precisely balanced ratios, often enhanced with trace elements (TE). When applied as foliar sprays, they are absorbed directly through leaf stomata, enabling rapid correction of nutrient deficiencies and significantly boosting crop performance at critical growth stages.
Foliar-applied water soluble NPK is absorbed within hours through leaf surfaces, bypassing soil fixation and delivering nutrients precisely when crops need them most — during flowering, fruiting, or stress recovery.
Customizable NPK ratios allow agronomists to tailor nutrient programs to specific crop growth stages — from high-phosphorus formulas for root establishment to high-potassium blends for fruit development and quality enhancement.
Zero insoluble residue ensures no nozzle clogging in drip systems or drone sprayers. High-purity crystalline formulations dissolve instantly in water, maintaining solution stability across a wide pH and temperature range.
Suitable for fertigation via drip, sprinkler, center pivot, flood irrigation, and aerial drone application — making it the most versatile nutrient delivery solution in modern precision agriculture.
Premium formulations include chelated micronutrients (Fe, Mn, Zn, Cu, B, Mo) that synergize with NPK to prevent hidden hunger, improve chlorophyll synthesis, and enhance overall crop immunity and market quality.
Higher nutrient use efficiency (NUE) compared to granular fertilizers reduces total input costs and environmental load. Less product is needed to achieve the same or superior agronomic outcomes.

Agricultural drones are transforming foliar nutrition delivery. The global agricultural drone market is projected to exceed USD 10 billion by 2030. Water soluble NPK fertilizers engineered for drone-grade compatibility — featuring ultra-fast dissolution and zero residue — are becoming the industry standard for aerial crop nutrition programs.
Drip fertigation systems now cover over 12 million hectares globally, with rapid expansion in the Middle East, North Africa, and Southeast Asia. Fully water soluble NPK fertilizers are the only viable nutrient source for these systems, driving sustained demand growth across all major agricultural markets.
The explosive growth of greenhouse horticulture, vertical farming, and hydroponic production worldwide demands premium water soluble NPK solutions. These closed-loop systems require 100% solubility, precise EC management, and compatibility with recirculating nutrient solutions — all hallmarks of professional-grade WSF products.
Water soluble NPK fertilizers unlock superior agronomic outcomes across a diverse range of crop systems and delivery technologies. Explore the key application scenarios driving commercial adoption globally.
High-potassium foliar NPK (e.g., NPK 15-15-30+TE) applied during fruit sizing and color development significantly improves Brix levels, skin firmness, shelf life, and export grading. Apple, citrus, mango, and grape growers report 15–25% quality improvement with targeted foliar programs.
Balanced NPK 20-20-20+TE provides uniform vegetative growth, enhanced leaf color, and improved nutrient density in lettuce, spinach, broccoli, and cabbage. Weekly foliar applications reduce crop cycle length by 5–10 days and increase marketable yield by up to 20%.
High-nitrogen foliar NPK (NPK 30-10-10+TE) applied at tillering and flag leaf stage in wheat, rice, and maize boosts grain filling efficiency and protein content. Drone-based application enables large-scale foliar nutrition of staple crops at fraction of traditional labor costs.
Precision water soluble NPK programs in cut flower and pot plant production deliver vibrant blooms, extended vase life, and superior stem strength. Greenhouse rose and chrysanthemum producers rely on weekly foliar feeding with balanced NPK+TE to meet international export quality standards.
In NFT, DWC, and substrate-based growing systems, water soluble NPK fertilizers serve as the primary nutrient source. Ultra-high purity formulations with controlled EC values and pH stability are essential for consistent plant performance in controlled environment agriculture.
Drone-grade water soluble NPK formulations must dissolve in under 60 seconds, leave zero residue in nozzles, and maintain solution stability at high concentrations. This specialized application is one of the fastest-growing segments in the global foliar fertilizer market.
Combining 20+ years of industry expertise with cutting-edge manufacturing technology, Luobu delivers water soluble NPK solutions that meet the most demanding agronomic and industrial standards worldwide.

Drone-Grade Monopotassium Phosphate (MKP) is the core product developed and manufactured by Sichuan Luobu New Material Technology Co., Ltd. It is specifically engineered and optimized for agricultural drone application, meeting the practical requirements of modern aerial spraying systems.
Drone-Grade MKP is formulated to ensure fast dissolution, stable purity, and compatibility with drone spraying equipment. In aerial operations, fertilizers must dissolve quickly and leave minimal residue to avoid clogging nozzles or affecting spray uniformity. Conventional products are often designed for ground application or irrigation systems and may not fully meet the technical demands of drone-based farming.
This innovation positions Luobu at the forefront of the precision agriculture revolution, where speed, reliability, and agronomic performance are non-negotiable requirements for commercial growers and agricultural service operators worldwide.
