Question

Nitrogen content of urea is ____________.
A) 46%
B) 36%
C) 26%
D) 56%

Answer 1

Urea has the maximum content of nitrogen and mostly used as nitrogen fertilizer. The pH value of urea is neutral, and it can adjust to almost all types of soil.

Complete answer:
Urea plays an important role in animal's metabolism of nitrogen-containing compounds and is the dominant nitrogen-containing material in mammalian urine. It is an odorless, extremely water-soluble, colorless, and virtually non-toxic solid. It is neither alkaline or acidic when dissolved in water. In several processes, most especially nitrogen excretion, the body uses it. It is formed by the liver by mixing two molecules of ammonia with one carbon dioxide molecule in the urea cycle. Urea is commonly used as a source of nitrogen in fertilizers and is a major raw material for the chemical industry.

With the highest content of nitrogen (about 46 percent), urea is the most effective nitrogen fertilizer on the market. It is an organic chemical compound named white crystalline. The pH value of urea is neutral and can adjust nearly all soil types. Urea is a white crystalline solid that contains 46% nitrogen as fertilizer and an animal feed additive. It is commonly used by the agricultural industry.

Thus, the correct answer is option A i.e., 46%.

Note: As a fertilizer that released nitrogen, more than 90 % of the world 's industrial supply of urea is intended for use. Of all solid nitrogen fertilizers in general use, urea has the maximum content of nitrogen. Therefore, urea has the minimum transport costs per nitrogen nutrient unit.
