Urea Fertilizer specification , Granular and Prill
Compared to the granular and urea fertilizer, we must say that N content of both is in the same range. Prill fertilizer is usually softer than granola. Usually the size of pearl is between 1 up to 2/4 mm but Granule is between 2 up to 4 mm. Some farmers prefer granules because they are gradually absorbed, and others think prill is better for faster absorption. It may seem strange, but based on the experience of Tradeinfact group, sometimes these two kinds of psychological aspects are chosen, and in some areas they prefer one to another.
