Urea Phosphate (UP 17.5-44-0) is a high-purity, fully water-soluble nitrogen and phosphorus fertilizer combining urea nitrogen with concentrated phosphate. Its distinctive acidity can lower the pH of alkaline irrigation water and improve nutrient availability. Highly soluble, it suits fertigation and suitable soil application, particularly in greenhouse and intensive production requiring combined N–P nutrition and water-quality management, and can also serve as a raw material for fertilizer blending.
