Question

Arrange the following in increasing the amount of nitrogen in the fertilizers:
(A). Ammonium sulphate,
(B). Ammonium nitrate,
(C). Ammonium chloride,
(D). Calcium ammonium nitrate

Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (A), (D), (C), (B)

Hint:

Remember: Ammonium sulphate has the lowest nitrogen content (21%) among these options, while Ammonium nitrate has the highest (33-34%).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Knowing the exact nutrient percentage of common chemical fertilizers is essential for calculating application rates and blending mixtures.

Step 2: Detailed Explanation:
Let us identify the standard nitrogen (% \(\text{N}\)) content of each fertilizer:
- (A) Ammonium sulphate contains approximately 21% \(\text{N}\).
- (D) Calcium ammonium nitrate (CAN) contains approximately 25% \(\text{N}\).
- (C) Ammonium chloride contains approximately 26% \(\text{N}\).
- (B) Ammonium nitrate contains approximately 33.5--34% \(\text{N}\).
Arranging these in increasing order of nitrogen content gives:
Ammonium sulphate (21%) \(\lt\) Calcium ammonium nitrate (25%) \(\lt\) Ammonium chloride (26%) \(\lt\) Ammonium nitrate (34%).
This corresponds to the sequence: (A), (D), (C), (B).

Step 3: Final Answer:
Hence, the correct option is (D).
