Urea 46 N

タイトルまたは説明

Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. Urea is solid, colorless, and odorless (although the ammonia that it gives off in the presence of water, including water vapor in the air, has a strong odor). Urea is highly soluble in water. In the past decade Urea has surpassed and nearly replaced ammonium nitrate as a nitrogen fertilizer. Urea is also widely used in the agricultural industry as an animal feed additive.
Urea fertilizer can be coated with certain materials, such as sulfur, to reduce the rate at which the nitrogen becomes available to plants. Under certain conditions these slow-release materials result in more efficient use by growing plants. Urea in a slow-release form is popular for use on golf courses, parks, and other special lawn situations.
Urea is neither combustible nor explosive. It can be stored safely with no loss of quality under normal circumstances. Small or fast-moving augers should not be used to move granular Urea. Urea particles are generally soft and abrasion can break the granules. Belt conveyers should be used whenever possible.
