UREA 46
Urea is the most concentrated nitrogen mineral fertilizer (contains 46% of N). It is a non-acid-forming fertilizer and can be used for all types of soil and for any crops as major fertilizer and in solution for additional foliar fertilization. Urea will be more effective then ammonium nitrate for irrigation and soil leaching. Besides, it is an essential nitrogen fertilizer by cultivation of rice and cucurbit crops.

UNCOATED UREA 46
Urea besides agriculture is used in industrial sectors too ,some of industrial areas urea grade should be uncoated.Uncoated urea is used to produce resines and adblue.
