1. Product Introduction & Main Application
Arnico’s Urea Prilled 46% is a solid, white, nitrogen-rich chemical fertilizer in the form of small, spherical prills, produced by the solidification of molten urea droplets in a prilling tower. With 46% nitrogen, this product is the most concentrated solid nitrogen fertilizer in the world, serving as the primary source of nitrogen for the vegetative growth of agricultural and horticultural crops, and is also a raw material for the production of urea-formaldehyde resins and DEF (AdBlue) solution.

3. Features & Benefits
-
The Highest Nitrogen Concentration (46%): Dramatically reduces transportation, warehousing, and per-hectare application costs compared to other nitrogen fertilizers.
-
Rapid & Complete Water Solubility: Ideal for use in fertigation systems and foliar spray applications.
-
Controlled Biuret: The technical grade, with its very low biuret content, is safe for the production of AdBlue and sensitive foliar applications.
-
Uniform Spherical Prills: Excellent flowability in fertilizer spreaders and no caking.
4. Industrial Applications
-
Agriculture & Horticulture: The primary top-dressing fertilizer in wheat, corn, rice, and citrus orchards.
-
Chemical Industry: A raw material in the production of urea-formaldehyde resins and MDF adhesives.
-
Automotive Industry: The production of AdBlue/DEF solution to reduce NOx emissions from diesel vehicles.
-
Animal Husbandry: A non-protein nitrogen source in the diet of dairy cattle.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance is non-toxic and non-flammable, but its dust is a mechanical eye and lung irritant. The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in completely moisture-proof bags, in a dry, cool warehouse, on pallets, and away from rain. It is highly hygroscopic and will cake.
-
Personal Protective Equipment (PPE): When decanting, the use of a P2 dust mask and safety goggles is recommended.
6. Quality Assurance & COA
Arnico Urea Prilled shipments are accompanied by a Certificate of Analysis (COA) detailing the nitrogen, biuret, and particle size percentages.
