High-Purity Urea Phosphate UP 17.5-44-0 from China Suppliers and Factory for Optimal Fertigation and Crop Performance
🌿 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)
Urea Phosphate is a fully water-soluble NP fertilizer combining nitrogen (17.5%) and phosphorus pentoxide (44.0%). It dissolves completely in water, making nutrients immediately available to plants. Its strong acidic nature (pH 1.6–2.4) also helps lower soil pH in the root zone, improving nutrient uptake efficiency.
Yes. Urea Phosphate is specifically designed for fertigation and drip irrigation. Its high solubility and very low water-insoluble matter (≤ 1000 ppm) prevent dripper clogging and ensure consistent, uniform nutrient delivery throughout the irrigation system.
Urea Phosphate is especially effective on alkaline and calcareous soils where phosphorus availability is typically limited. Its acidifying properties help reduce soil pH in the root zone, making it an excellent choice for growers dealing with high-pH soil conditions. It can also be used on neutral soils with appropriate rate adjustments.
Urea Phosphate is compatible with most water-soluble fertilizers and is widely used as a component in NPK blends and liquid fertilizer formulations. However, it is recommended to perform a jar compatibility test before mixing with calcium- or magnesium-based fertilizers to avoid precipitation.
Urea Phosphate is widely used across a broad range of crops, including field crops, fruit trees, vegetables, and greenhouse plants. It is particularly beneficial during early growth stages when strong root development and rapid phosphorus uptake are critical for establishing healthy plants.
Urea Phosphate is available in standard 25 kg bags. OEM and ODM customized packaging options are also available upon request, allowing distributors and manufacturers to tailor packaging to their specific branding and market requirements.
