Fully dissolves in water within 2 minutes with zero residue. Will not clog drip emitters, spray nozzles, or irrigation systems.
Iron, zinc, manganese, and copper are chelated (EDTA/DTPA) to remain stable and fully available in solution, preventing precipitation and nutrient lock-up.
Combines nitrate, ammoniacal, and urea nitrogen for rapid uptake, sustained release, and balanced nutrition across all growth stages.
Direct delivery to root zone or leaf surface achieves 90%+ nutrient utilization, far exceeding the 30-40% of conventional soil application.
Foliar or fertigation application provides visible nutrient response within 3-5 days, ideal for correcting mid-season deficiencies.
Manufactured to ISO 9001 standards with SGS pre-shipment inspection. Full COA provided with every shipment.
WS NPK 20-20-20+TE is designed for fertigation, drip irrigation, and foliar application in high-value crop production systems.
Tomato, cucumber, pepper, strawberry, leafy greens. Fertigation at 2-5g/L throughout growth cycle.
Apple, citrus, grape, banana, mango. Foliar spray at 1-3g/L or fertigation during flowering and fruiting.
Coffee, cocoa, tobacco, ornamentals, medicinal crops. Foliar or drip application for precision nutrition.
| Crop Stage | Application Rate | Method |
|---|---|---|
| Foliar spray | 1-3 g/L (0.1-0.3% solution) | Every 7-14 days |
| Drip fertigation | 2-5 g/L per irrigation | 2-3 times per week |
| Hydroponics | 1.0-1.5 g/L stock solution | Continuous / daily |
