What is the formula for urea fertilizer?
CO(NH2)2
The chemical formula of urea is CO(NH2)2 and, in nature, urea is excreted in the urine of mammals. Commercial urea fertilizers are produced by reacting ammonia with carbon dioxide.
How many types of urea are there?
In addition to their value as a nitrogen source, urea fertilizers are also non-toxic, nonflammable, highly soluble, and neither alkaline nor acidic when suspended in water. The most common urea fertilizer types are the crystalline and granular variants.
What is granular urea used for?
Urea is the most widely used nitrogen fertilizer in the world. It is effective on all crops, including regions with a warm climate. Urea is a synthesized organic molecule that is easily accessible to plants and can be absorbed by all parts of plants, both roots and vegetative mass.
What is the difference between prilled and granular urea?
Prilled urea and granular urea are two types of solid nitrogen fertilizers. The key difference between prilled and granular urea is that prilled urea takes a little time to dissolve in water, whereas granular urea takes a lot of time to dissolve.
What is the pH of urea fertilizer?
These values typically vary from 3.6 to 7.2 for the N fertilizers that are typically used (See Table 1)….The Role of Nitrogen Fertilizer on Soil pH.
| Fertilizer | % N | Pounds of ECC needed to neutralize 1 pound of actual N |
|---|---|---|
| Urea | 46% | 3.6 |
| UAN Solutions | 28-32% | 3.6 |
| Diammonium Phosphate (DAP) | 18% | 5.4 |
| Ammonium Sulfate | 21% | 7.2 |
What is the formula of amine?
Amine molecules have the general formula of R3-xNHx where R is a hydrocarbon group, and x is an integer with 0 < x < 3. Put another way, amines are derivatives of ammonia, NH3, in which one or more hydrogen atoms have been replaced by hydrocarbon groups.
