Urea is widely used in the agricultural industry as an animal feed additive and fertilizer. With 46 percent nitrogen, it is an efficient source of nitrogen in fertilizers.
Urea is a water soluble white crystalline solid organic compound. It has the chemical formula of CO(NH2)2, containing 46 percent nitrogen. Urea is used both as cattle feed and fertilizer for providing nitrogen. In the context of "prilled urea," fertilization is the relevant use.
Chemists first synthesized urea in the early 1800s.
Prilled urea, or "prills" are formed by dropping liquid urea from a prilling tower into droplets that dry into roughly spherical shapes 1mm to 4 mm in diameter.
Granular urea is chemically the same as prilled urea. Granular urea, however, is slightly larger and harder. Today, the use of prilled urea is more prevalent because it is more resistant to breaking down when being blended with the other components of fertilizer.
Urea was the first organic compound successfully synthesized by chemists in the early 1800s.
Water the area immediately to dilute the dog urine before it has time to damage the grass. If neighborhood dogs are the issue, water daily to help keep any urine in the lawn diluted so it doesn't cause damage.
Avoid adding nitrogen-rich or urea-based fertilizers to the affected area during your normal fertilizer routine. These fertilizers will just add to the problem and cause further burning or grass death.
Rake the damaged area to remove the dead grass and thatch, revealing some of the soil beneath. Spread fresh grass seed over the location, using the same type of seed as the surrounding lawn grass. Keep the seed bed moist until the seeds germinate and the grass establishes.
Remove the entire patch if the grass is completely dead. Dig up the grass and up to 1 inch of the topsoil. Cut a sod piece to fit the bare spot and set it in place. Keep the sod evenly moist until the roots establish in the soil beneath.
Due to it's high nitrogen content, the majority of urea is used to make fertilizer. Nitrogen helps plants grow quickly and aids in the production of a healthy and abundant crop. In addition to providing ample nitrogen, urea is also useful because it can be used as either a solid or a solution. In addition, there are very few hazards associated with the use of urea, and it does not release as many pollutants into the air as other nitrogen sources.
Urea is also found in cattle feed, because it provides the animals with a good source of nitrogen.
The high nitrogen content found in urea is useful to the cosmetic industry as well. A number of skin creams contain urea because it helps to moisturize and nourish skin. In addition to providing nitrogen, a necessary ingredient to treating rough, dry skin, urea is also antibacterial and antimicrobial. Another advantage of using urea in skin creams is that it requires fewer preservatives to maintain product freshness.
Urea is also used to help improve the environment. In addition to its use as a fertilizer, which does not pollute the air, urea also lowers NOx emissions in vehicles. NOx refers to a group of "highly reactive gasses" according to the Environmental Protection Agency. These gasses can cause respiratory problems and assist in the formation of ozone.
The Institute of Clean Air Companies notes that urea and similar agents have been found to lower NOx emissions by up to 75%.
