UP Fertilizer
Urea Phosphate 17-44-0
Urea Phosphate Fertilizer Manufacturer & Supplier
Risso UP Fertilizer is a high-purity, water-soluble nitrogen and phosphorus fertilizer containing approximately 17% nitrogen (N) and 44% phosphorus pentoxide (P₂O₅).
What Is UP Fertilizer?
UP fertilizer is Urea Phosphate, a water-soluble nitrogen-phosphorus fertilizer commonly identified by the fertilizer grade 17-44-0.
UP is produced by reacting urea with phosphoric acid, forming a crystalline fertilizer that combines nitrogen and phosphorus in one product.
A typical UP fertilizer contains:- 17% Total Nitrogen (N)
- 44% Available Phosphate, expressed as P₂O₅
- 0% Potassium (K₂O)
The combination of relatively high phosphorus content, water solubility and acidic reaction makes UP particularly relevant to fertigation and precision nutrient management.
Compared with conventional nitrogen fertilizers such as urea, UP supplies both nitrogen and phosphorus. Compared with MAP, UP generally provides more nitrogen but less P₂O₅.

FREQUENTLY ASKED QUESTIONS
UP fertilizer is Urea Phosphate, a water-soluble nitrogen-phosphorus fertilizer commonly sold under the grade 17-44-0. supplied in nitrate and ammonium forms.
The numbers represent the fertilizer's N-P-K analysis:
17% nitrogen (N) – 44% phosphorus pentoxide (P₂O₅) – 0% potassium (K₂O).
Yes. Fertilizer-grade UP is a highly water-soluble material commonly used in fertigation and water-soluble fertilizer formulations.
Yes. Its water solubility makes UP suitable for fertigation and drip irrigation applications when the product is correctly dissolved and used according to the irrigation system and fertilizer program.
Yes. Urea phosphate produces an acidic solution when dissolved in water. The exact pH depends on the test conditions and product specification.
UP may be useful in fertilizer programs involving alkaline or high-pH conditions because of its acidic reaction. However, application should be based on soil testing, irrigation water quality and the complete nutrient management program.
UP typically contains 17% N and 44% P₂O₅, while MAP commonly contains 12% N and 61% P₂O₅. UP supplies more nitrogen per unit of product, while MAP provides a higher concentration of P₂O₅.
Urea is a concentrated nitrogen fertilizer, commonly graded 46-0-0. UP is typically graded 17-44-0, providing both nitrogen and phosphorus.
Yes. UP can be used as a raw material in water-soluble NP and NPK fertilizer formulations, provided that the formulation is chemically compatible.
Risso supplies fertilizer products for international markets. Buyers can contact Risso with their required grade, quantity, packaging and destination to discuss availability and export supply arrangements.
