INTRODUCTION
Urea ( free flowing ) is one of the most widely used nitrogen fertilizers in agriculture. It is valued for its high nitrogen content, easy handling, and efficient application properties. The specification of urea ( free flowing ) defines its physical, chemical, and quality characteristics to ensure safe storage, transport, and agricultural performance.
WHAT IS UREA ( FREE FLOWING )
Urea ( free flowing ) is a solid nitrogen fertilizer in prilled or granular form designed to maintain good flowability without caking or clumping during storage. The free flowing characteristic ensures smooth mechanical handling and uniform field application.
CHEMICAL SPECIFICATION OF UREA ( FREE FLOWING )
The chemical specification of urea ( free flowing ) focuses on nitrogen concentration and purity.
Key chemical characteristics include:
-
High nitrogen content
-
Low biuret content
-
Minimal impurities
-
Stable chemical composition
Controlled chemical properties ensure effective nitrogen supply.
PHYSICAL SPECIFICATION OF UREA ( FREE FLOWING )
Physical specification plays a critical role in defining urea ( free flowing ) quality.
GRANULE SIZE
Uniform particle size ensures even distribution during application and reduces dust formation.
FLOWABILITY
Free flowing structure prevents caking and ensures smooth movement through storage systems and application equipment.
HARDNESS AND STRENGTH
Granule strength protects urea ( free flowing ) from breakage during handling and transportation.
MOISTURE CONTENT
Low moisture content improves storage stability and prevents lump formation.
