Description
Nitrogen-based fertilizer that is produced by reacting ammonia and carbon dioxide. Urea is the most widely used fertilizer in the world, as it provides a high concentration of nitrogen and is easy to store and transport. Urea can be applied to the soil or sprayed on the leaves of the plants. Urea improves the yield and quality of crops, but it also can cause environmental problems such as nitrate leaching and greenhouse gas emissions.
