Acidic, fully water-soluble nitrogen-phosphorus fertilizer for saline-alkali soil improvement and precision fertigation.
Product Overview
UP (Urea Phosphate) is a highly water-soluble acidic nitrogen-phosphorus fertilizer formed from urea and phosphoric acid. Its strong acidity makes it valuable in fertigation systems where pH adjustment, phosphorus availability and irrigation line maintenance are important.
It is especially suitable for saline-alkali soil improvement, drip irrigation, fertigation and crops requiring efficient phosphorus supply under challenging soil conditions.
