Industrial processing of carbon dioxide and ammonia by the method of synthesis made it possible to obtain a useful product. It is a urea or urea fertilizer that contains 46% nitrogen.
Urea (or urea) is one of the main nitrogen - containing fertilizers for foliar feeding of plants. Agrochemical looks like, colorless to white (sometimes with a yellow shade) crystals, which are odorless.
Chemical formula: H2N-CO-NH2.
Urea fertilizer is available in two grades:
Grade A for the industrial use. It is used as a raw material for making resins, glue, or in animal husbandry, as a feed additive.
Mark b is exclusively for agriculture. This mark is used to fertilize winter crops, vegetable and row crops of plants.
