🌿 Product Overview
Urea Phosphate (UP 17.5-44-0) is a premium water-soluble NP fertilizer designed for modern agriculture systems, especially fertigation and precision irrigation. It provides a highly efficient combination of nitrogen (N) and phosphorus (P₂O₅) in a readily available form for plants.
Due to its strong acidic nature, Urea Phosphate is particularly suitable for alkaline and calcareous soils, where it helps reduce pH in the root zone and significantly improves the availability of phosphorus and micronutrients.
With excellent solubility and low impurity levels, UP ensures smooth operation in drip irrigation systems, preventing clogging and maintaining uniform nutrient delivery. It is widely used in field crops, fruit trees, vegetables, and greenhouse cultivation.
Its compatibility with most fertilizers makes it an ideal component for fertilizer blends and liquid fertilizer production, supporting flexible nutrient management programs.
✅ Key Benefit: Dual-function fertilizer — delivers essential N & P nutrition while simultaneously acidifying the root zone for improved nutrient uptake.

❓ Frequently Asked Questions (FAQ)
📌 What is Urea Phosphate (UP) and what does 17.5-44-0 mean?
Urea Phosphate (UP) is a fully water-soluble NP fertilizer with the chemical formula CO(NH₂)₂·H₃PO₄. The grade 17.5-44-0 refers to its nutrient content: 17.5% total nitrogen (N), 44% phosphorus pentoxide (P₂O₅), and 0% potassium (K₂O). It is widely used in fertigation and precision agriculture.
📌 Is Urea Phosphate suitable for drip irrigation systems?
Yes. Urea Phosphate is specifically formulated for drip and sprinkler irrigation. Its very high water solubility and ultra-low insoluble matter content (≤ 1000 ppm) ensure clean, clog-free performance in emitters and irrigation lines, maintaining uniform nutrient delivery across the field.
📌 Why is Urea Phosphate recommended for alkaline soils?
Urea Phosphate has a very low pH (1.6–2.4 in a 10% solution), making it a powerful soil acidifier. When applied to alkaline or calcareous soils, it reduces pH in the root zone, which significantly improves the solubility and plant availability of phosphorus and key micronutrients that are otherwise locked up at high pH levels.
📌 Can Urea Phosphate be used for foliar application?
Yes, Urea Phosphate can be applied as a foliar spray to provide a rapid supply of nitrogen and phosphorus directly to plant leaves. It is particularly useful during early growth stages to support root development and correct nutrient deficiencies quickly. Always follow recommended dilution rates to avoid leaf burn.
📌 Is Urea Phosphate compatible with other fertilizers?
Urea Phosphate is compatible with most water-soluble fertilizers and is widely used as a base component in NPK blends and liquid fertilizer formulations. Its chelating properties also help keep calcium, magnesium, and other metal ions in solution, improving the stability of complex nutrient mixes. Always conduct a jar test before large-scale mixing.
📌 What crops benefit most from Urea Phosphate application?
Urea Phosphate is suitable for a wide range of crops, including vegetables, fruit trees, field crops, and greenhouse plants. It is especially beneficial during the transplanting and early vegetative stages when phosphorus demand is high and rapid root establishment is critical. It is also highly effective for crops grown in alkaline or calcareous soil environments.
