Urea Ammonium Nitrate Solution
Main Advantages
-
High nitrogen content with multiple forms of nitrogen: Contains both ammonium (NH₄⁺) and nitrate (NO₃⁻) forms, providing quick and long-lasting nutrient supply.
-
Fast absorption and quick results: Nitrate nitrogen can be absorbed immediately by the roots, promoting chlorophyll synthesis and rapid growth.
-
Flexible application methods: Can be used as a base fertilizer, topdressing, or through drip irrigation, foliar spraying, and fertigation systems.
-
Excellent solubility and easy mixing: Compatible with most water-soluble fertilizers and trace elements (pre-test recommended), convenient for blending and on-site application.
TWO
-
Reduced nitrogen fixation losses: Compared with pure urea, the presence of nitrate nitrogen reduces the risk of temporary nitrogen fixation in the soil.
-
Improved fertilizer efficiency: Enhances nitrogen utilization, reduces fertilizer frequency, and lowers labor costs when used with scientific fertilization practices.
-
Ideal for mechanized and precision agriculture: Liquid form allows for precise dosing and use in automated fertilization systems.
-
Efficient transportation and storage: Higher effective nitrogen per unit volume compared to solid fertilizers, suitable for large-scale continuous application.
-
Spring topdressing or grain-filling stage for rapid nitrogen supply.
-
Drip irrigation systems in vegetable and greenhouse cultivation.
-
Foliar spraying (with proper dilution and according to crop tolerance).
-
Control concentration carefully to avoid leaf burn during foliar spraying.
-
Always perform a compatibility test before mixing with trace elements or alkaline pesticides.
-
Slightly corrosive—use corrosion-resistant containers and pipelines.
-
Avoid surface application under hot or dry conditions to reduce volatilization; combine with irrigation for better efficiency.
