Which substance is commonly recognized as a chemical fertilizer?

• A. Ammonium nitrate
• B. Sucrose
• C. Sulphate
• D. Chlorophyll

Answer: (C)

The correct answer is ammonium nitrate, which is a widely used chemical fertilizer known for providing both nitrogen and, to a smaller degree, ammonia to plants. Ammonium nitrate is particularly efficient because it delivers nutrients rapidly to plants, promoting leafy growth and improving overall plant health. While sulphate is a compound that can be part of fertilizers, it is not recognized as a standalone chemical fertilizer in the same way ammonium nitrate is, which is a complete, commercially available product designed specifically for enhancing agricultural productivity. Sucrose, commonly known as table sugar, is not a fertilizer but rather a carbohydrate used by plants for energy; it does not provide essential nutrients for growth. Chlorophyll is a pigment crucial for photosynthesis in plants, but it is not a fertilizer either. Understanding the specific roles and definitions of these substances helps in identifying ammonium nitrate’s unique position as a chemical fertilizer.
