✅ Applications of Urea Phosphate in Agriculture
⭐ 1. Fertigation (Drip and Sprinkler Irrigation)
Highly efficient nitrogen and phosphorus source for fertigation systems.
Recommended Dosage: 2–4 kg/acre per application depending on crop and growth stage.
Compatible with calcium- and magnesium-free fertilizers for drip systems.
⭐ 2. Acidification of Irrigation Water
Strongly acidic nature makes urea phosphate effective in lowering pH of alkaline irrigation water.
Helps prevent clogging of drip irrigation lines caused by calcium and magnesium precipitates.
⭐ 3. Foliar Fertilization
Supplies quick nitrogen and phosphorus to plants via foliar sprays.
Recommended Concentration: 0.5–1.0% solution (5–10 g/L water).
Effective for correcting phosphorus deficiencies during critical growth stages.
⭐ 4. Promotes Root and Flower Development
High phosphorus content enhances root initiation, flowering, and fruit development.
Boosts plant resistance against stress and improves nutrient uptake efficiency.
⭐ 5. Suitable for High-Value Crops:
Fruits: Citrus, grapes, bananas, strawberries.
Vegetables: Tomatoes, cucumbers, peppers.
Flowers & Ornamentals: Roses, gerberas, orchids.
Field Crops: Cotton, corn, and more.
✅ Advantages of Urea Phosphate:
✅ Dual nutrient source of nitrogen and phosphorus.
✅ Chloride-free and sulfate-free, safe for sensitive crops.
✅ Highly acidic, improves nutrient solubility and availability in alkaline soils.
✅ Prevents scaling in irrigation systems.
✅ Compatible with other fertilizers (except calcium and magnesium fertilizers).
✅ Packaging and Storage:
Standard Packaging: 25 kg or 50 kg plastic woven bags with PE inner lining.
Bulk Supply: Available for agricultural distributors.
Storage Conditions: Store in a cool, dry, ventilated place; keep away from moisture and direct sunlight.
✅ Conclusion:
Urea Phosphate is an advanced high-efficiency fertilizer combining nitrogen and phosphorus, ideal for modern fertigation and foliar applications. Its acidic properties enhance nutrient availability and help manage water quality in irrigation systems. Suitable for a wide range of crops, it is an essential tool for improving yields, quality, and soil health.
