說明

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. SABIC
produces and markets both Prilled and Granular Urea, thus giving customers a flexible choice to suit their requirements.
