Q. Consider the following:
- Diammonium phosphate (DAP)
- Muriate of potash (MOP)
- Calcium Carbonate
- Ammonium sulfide
Which of the above is/are commonly used as fertilizers in agriculture?
Answer:
1, 2 and 3
Notes:
- Fertilizers are substances that are added to soil to improve plant growth and crop yields. They provide essential nutrients like nitrogen (N), phosphorus (P), and potassium (K).
- The most commonly used fertilizers in agriculture are urea, diammonium phosphate (DAP), and muriate of potash (MOP).
- Calcium carbonate, also known as limestone, is a natural fertilizer that helps improve soil pH and supplies calcium to plants.
- Ammonium sulfide ((NH4)2S) is not used as a fertilizer, whereas ammonium sulfate ((NH4)2SO4) is commonly used.
