Question

Which of the following fertilisers provides maximum amount of nitrogen?

• A. Calcium Nitrate
• B. Urea
• C. Ammonium Sulphate
• D. Nitrolium

Answer 1

The correct option is B Urea

Urea.

Of the commonly used dry fertilizers, urea contains the highest percentage of nitrogen and is rapidly replacing ammonium nitrate. When surface applied, urea is the most readily volatilized of the dry nitrogen materials. After application to the soil, urea will hydrolyze (combine with water) to form ammonium carbonate.
