🌿 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.

❓ Frequently Asked Questions (FAQ)
❓ What is Urea Phosphate (UP 17.5-44-0) and how does it differ from other NP fertilizers?
Urea Phosphate is a fully water-soluble NP fertilizer with the chemical formula CO(NH₂)₂·H₃PO₄. Unlike conventional NP fertilizers, it has a strongly acidic pH (1.6–2.4 in a 10% solution), which makes it uniquely effective in alkaline and calcareous soils. It simultaneously provides nitrogen and phosphorus while acidifying the root zone to improve nutrient availability.
❓ Is Urea Phosphate safe to use in drip irrigation systems?
Yes. Urea Phosphate is specifically formulated for fertigation use. Its high water solubility and extremely low water-insoluble matter content (≤ 1000 ppm) ensure that drip lines and emitters remain clog-free, maintaining consistent and uniform nutrient delivery throughout the irrigation system.
❓ Which crops and soil types benefit most from Urea Phosphate?
Urea Phosphate is most beneficial for crops grown in alkaline or calcareous soils, including fruit trees, vegetables, field crops, and greenhouse plants. Its acidifying effect lowers the soil pH in the root zone, significantly enhancing phosphorus and micronutrient uptake — making it ideal for any crop that requires rapid early-stage phosphorus supply.
❓ Can Urea Phosphate be mixed with other fertilizers?
Urea Phosphate is compatible with most water-soluble fertilizers and is widely used in NPK blends and liquid fertilizer production. However, as with all fertilizers, it is recommended to perform a small-scale compatibility test before large-scale mixing, especially with calcium or magnesium-containing fertilizers, to avoid potential precipitation.
❓ What packaging options are available, and can custom packaging be arranged?
Urea Phosphate is available in standard 25 kg bags suitable for both retail and bulk agricultural use. Custom OEM/ODM packaging can be arranged upon request, allowing distributors and manufacturers to brand the product according to their market requirements. Please contact us for more details on customized packaging solutions.
❓ How does Urea Phosphate contribute to long-term soil health?
Beyond providing immediate crop nutrition, Urea Phosphate acts as a soil amendment by gradually reducing excessive alkalinity in the root zone. Its chelating properties help mobilize Ca²⁺, Mg²⁺, and other metal ions, improving overall soil structure and micronutrient availability over time. This dual function — nutrition and acidification — supports both short-term crop performance and long-term soil productivity.
