Product Introduction
Product Description
Seaweed Phosphorus-Potassium UAV Special Liquid (Liquid PK 900 UAV Fertilizer) is a high-quality substitute for monopotassium phosphate. Monopotassium phosphate dissolves slowly, which may lead to poor dissolution and nozzle clogging, delaying UAV operation progress. This product uses liquid chelated phosphorus-potassium technology to effectively solve this problem, with high phosphorus and potassium content, capable of replacing monopotassium phosphate. The product dissolves instantly in water, no waiting required, saving time and labor.
Core Advantages
- Potassium Dihydrogen Phosphate SubstituteHigh phosphorus-potassium content, P₂O₅≥400g/L, K₂O≥500g/L, can completely replace monopotassium phosphate.
- Instantly soluble in waterLiquid formulation, no waiting for dissolution, no nozzle clogging, ensures smooth aerial application operations.
- Time and Labor SavingReduces dissolution time, improves operational efficiency, and lowers labor costs.
- Sugar Alcohol Chelation TechnologyContains ≥30g/L sugar alcohols to enhance crop absorption and utilization of phosphorus and potassium.
- High-concentration LiquidDensity 1.65g/cm³, stable content, easy to transport and store.
- Designed for Aerial ApplicationOptimized for drone spraying, compatible with various plant protection drones.

- Application interval: 7–10 days
- Note: Conduct a small-scale test first when mixing with other agents.
Foliar Spray
Rapidly replenishes phosphorus and potassium nutrients, promotes crop growth and development, and improves fruit quality.
- Field crop dilution: 400 — 800 times
- Fruit tree and vegetable dilution: 600 — 1500 times
- Application rate: 30 — 60 L/mu
- Time: Morning or evening, avoid high temperatures
Drip Irrigation and Topdressing
Suitable for facility agriculture and water-saving irrigation systems, enabling precise fertilization.

Applicable Crops and Recommended Dosage
| Crop Type | Representative Crops | Recommended Dilution Ratio | Application Period |
|---|---|---|---|
| Field Crops | Wheat, corn, rice | 400 — 800 times dilution | Jointing Stage, Booting Stage, Filling Stage |
| Fruit Trees | Apple, Pear, Peach, Grape, Citrus | 600 — 1500 times dilution | Apply multiple times from early fruit set to maturity |
| Solanaceous Vegetables | Tomato, cucumber, pepper, eggplant | 600–1200 times dilution | Flowering Stage, Fruiting Stage, Expansion Stage |
| Legume Crops | Soybean, peanut, pea | 400 — 800 times dilution | Flowering stage, pod-setting stage (better nitrogen fixation effect) |
| Cash Crops | Cotton, tobacco, tea plants | 500–1000 times dilution | Mid to Late Growth Stage |
- Store in a cool, dry place away from direct sunlight; shake well before use.
- This product is a high-concentration liquid; any sedimentation is normal and does not affect fertilizer efficacy.
- Ensure the drone spraying system is clean and unobstructed during aerial application.
- Compatible with most fertilizers and pesticides, but small-scale testing prior to use is recommended.
- For cash crops such as fruit trees, multiple applications from early fruit set to maturity are recommended for optimal results.
FAQ
The main difference lies in the formulation and solubility characteristics.
- Monopotassium PhosphateSolid powder form, requires dissolution before use, dissolves relatively slowly, may lead to incomplete dissolution and potential nozzle clogging.
- Liquid Potassium Phosphate FertilizerColorless transparent liquid, dissolves instantly in water, no waiting time required, does not clog nozzles, specially optimized for UAV operations.
- Nutritional CompositionThis product contains P₂O₅≥400g/L, K₂O≥500g/L, total phosphorus-potassium content≥900g/L, and added sugar alcohol≥30g/L to improve absorption and utilization.
Aerial application has the following specific requirements for fertilizers:
- Dissolution RateShort time windows for drone operations require fertilizers that dissolve instantly upon contact with water, avoiding delays in work progress.
- Clog-FreeIncomplete dissolution of solid fertilizers can clog nozzles, affecting operational efficiency and even damaging equipment.
- Easy to DiluteLiquid fertilizers are easier to evenly dilute and proportion
- High ConcentrationReduce dosing frequency and improve operational efficiency
- Excellent CompatibilityNeeds to be used in combination with various pesticides
This product fully meets the above requirements and is an ideal choice for aerial application.
According to the crop growth cycle and fertilizer requirements:
- Field CropsApply during jointing, booting, and filling stages to promote plump grains and increase yield.
- Fruit TreesMultiple applications from early fruit set to maturity promote fruit expansion and improve quality.
- Solanaceous VegetablesApply during flowering, fruiting, and expansion stages to improve fruit set rate and promote fruit development.
- Legume CropsBest used during flowering and pod-setting stages for enhanced nitrogen fixation.
Recommended application interval: 7-10 days for optimal results with continuous use.
