Features and Applications:
Urea is a type of nitrogen fertilizer of high purification belonging to the neutral readily available fertilizer. It exerts no harm or hazard residues in soil for long time use. It can be used as feeds for cud chewer. It can also improve glossing on steel or stainless steel and used as inhibiter in acid-pickling and Pd-active catalyst. Urea also finds applications in medicine, dyeing, fabrics, dynamite, refining, etc.

Urea can be applied as base fertilizer and topdressing on all types of crops and in dry land or paddy field. After application to the soil, urea undergoes chemical changes and ammonium (NH4 +) ions form. When a urea particle dissolves, the area around it becomes a zone of high pH and ammonia concentration. Seed and seedling roots within this zone can be killed by the free ammonia with 500ppm concentration. Under no circumstances should urea or urea-based fertilizer be seed-placed. The organic nitrogenous fertilizer will be absorbed by crops after converting to ammonium carbonate or ammonium bicarbonate under urease processing in the soil. Usually it should be spread just4-8 days before plants can effectively use the nitrogen.

It is packed in 50kg plastic bag and customized bag is available.
