Urea is made when carbon dioxide is reacted with ammonia. The process occurs under extreme pressures, around 180 degrees Celsius. Urea is processed to take the form granules.
When applied urea is converted to ammonium by the action of urease, a naturally occurring enzyme present in the soil. This process is known as ammonification and is usually completed within a few days. Soil bacteria then converts the ammonium to nitrate. The nitrification and is usually completed within a few weeks.
High analysis form of nitrogen, used as a straight fertiliser and in blends.
