Urea is the most popular and economical of all nitrogenous fertilizers being used worldwide. Urea has a nitrogen content of 46%, a higher concentration than this is available in other solid sources of nitrogen. Unlike phosphate and potassium fertilizers, which normally require a single application, urea needs to be applied several times during the growing season. Urea is an ideal source of nitrogen for all kinds of crops (wheat, barley, rice, maize etc.) In addition, urea is a major raw material for melamine, and an important raw material for the manufacture of other industrial products.

Broadcasting or in irrigation water (fertigation); often more effective if applied at least three times throughout the growing season; suitable for a wide variety of crops across a wide range of environmental conditions.
STORAGE AND HANDLING
The product is normally stored in bulk and in bags.
PACKAGING
The product is mainly exported in bulk. Also, in 1000 and 50 kg bags.
