    🌿 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 combines nitrogen and phosphorus in a single compound with a strongly acidic pH (1.6–2.4), making it uniquely effective for alkaline soil correction and precision fertigation where clean, clog-free nutrient delivery is essential.
    📌 Is Urea Phosphate suitable for drip irrigation systems?
    Yes. Urea Phosphate is specifically designed for drip irrigation and fertigation systems. Its high water solubility and very low water-insoluble matter content (≤ 1000 ppm) prevent dripper clogging and ensure consistent, uniform nutrient distribution throughout the irrigation network.
    📌 How does Urea Phosphate help with alkaline and calcareous soils?
    Due to its strongly acidic nature, Urea Phosphate lowers the pH in the root zone when applied to alkaline or calcareous soils. This pH reduction significantly improves the availability of phosphorus and key micronutrients that are otherwise locked up in high-pH soils, leading to better nutrient uptake and crop performance.
    📌 Can Urea Phosphate be used for foliar application?
    Yes, Urea Phosphate can be applied as a foliar spray to provide a rapid supply of both phosphorus and nitrogen to plants. It is particularly useful during early growth stages to support root development and quick nutrient response. Appropriate dilution rates should be followed to avoid leaf burn.
    📌 Is Urea Phosphate compatible with other fertilizers in blends or liquid formulations?
    Urea Phosphate is compatible with most water-soluble fertilizers, making it an excellent component for NPK blends and liquid fertilizer production. It is widely used by fertilizer manufacturers to create customized nutrient solutions. However, compatibility testing is recommended before large-scale mixing, particularly with calcium- or magnesium-based fertilizers.
    📌 What packaging options are available for Urea Phosphate?
    Urea Phosphate is available in standard 25 kg bags. OEM and ODM customized packaging is also available upon request, allowing distributors and manufacturers to brand the product according to their specific market requirements.
