Urea with a 46 percent nitrogen content, is a solid nitrogen fertilizer product. Urea fertilizers are widely used in agriculture. It is the most common form of nitrogen fertilizer used around the world. They are considered as economic nitrogen source. It has the highest nitrogen content of any solid nitrogen fertilizer. As a granular product, urea can be applied directly to the soil using conventional spreading equipment. In addition to soil applications, urea fertilizers can be also used in fertigation or as a foliar application. However, urea fertilizers should not be used in soil less culture, as urea will immediately leach out of the container. In its solid form, urea is provided as either prilled or granules. Granules are slightly larger than prilled and are more dense. Both prilled and granular urea fertilizers contain 46% N.
