Urea Phosphate (UP 17.5-44-0)
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.
