1. Product Introduction & Main Application
Arnico’s Urea Granular 46% is a solid, white, nitrogen-rich chemical fertilizer in the form of hard, spherical granules, produced from the reaction of carbon dioxide with ammonia under high pressure. 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 arable, horticultural, and vegetable 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.
-
Controlled Biuret: The technical grade, with its very low biuret content, is safe for foliar application and AdBlue production.
-
Hard & Resistant Granules: No crushing or dust generation during transport and application with centrifugal spreaders.
-
Excellent Water Solubility: Suitable for pressurized irrigation systems (fertigation) and foliar spraying.
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.
