Arrange these fertilizers as per nitrogen content (Higher to lower): A. Urea B. Ammonium sulphate C. Ammonium chloride D. Ammonium nitrate E. Di-ammonium phosphate

Correct option is A

Correct Answer: (A) A → D → C → B →E
This arrangement is based on the percentage of nitrogen content present in different fertilizers, as per standard ICAR and TNAU fertilizer composition data.

Urea (A) contains 46% N, making it the highest nitrogen-containing fertilizer among the given options.

Ammonium nitrate (D) contains about 33–34% N, which is second highest.

Ammonium chloride (C) contains around 25–26% N, lower than ammonium nitrate but higher than ammonium sulphate.

Ammonium sulphate (B) contains about 20–21% N, making it lower than ammonium chloride.

Di-ammonium phosphate (DAP) (E) contains approximately 18% N, which is the lowest among the given fertilizers.

Therefore, the correct order from higher to lower nitrogen content is:
Urea → Ammonium nitrate → Ammonium chloride → Ammonium sulphate → DAP

Information Booster:

Urea: 46% N – most concentrated solid nitrogen fertilizer.

Ammonium nitrate: ~33–34% N – highly soluble and quick acting.

Ammonium chloride: ~25–26% N – commonly used in paddy fields.

Ammonium sulphate: ~20–21% N – also supplies sulphur.

DAP: ~18% N – mainly a phosphatic fertilizer with secondary nitrogen content.

Additional Knowledge:

Fertilizers are often classified based on nutrient concentration and solubility.

High nitrogen fertilizers like urea are widely used for rapid vegetative growth.

Balanced fertilization is important, as excessive nitrogen can lead to lodging and reduced crop quality.
