Urea, also known as nitrogen (N) fertilizer, has a nitrogen content of 46%. Urea is produced from a chemical reaction between ammonia and carbon dioxide, which results in solid urea in prill form (size 1-3 mm) or granule form (size 2-4 mm), both produced by Pupuk Kaltim. Prill urea is mostly used by the food crops and industry sector, while granule urea is more suitable for the plantation sector, although it can also be used in the food crops sector. Urea are marketed and sold under the trademark Mandau, Daun Buah and Pupuk Indonesia. The brand Pupuk Indonesia is used especially for the pink-colored subsidized urea.
