Which of the following fertilizers cannot replenish nitrogen?

Options

A. Super phosphate of lime (calcium dihydrogen phosphate with gypsum)
B. Nitre
C. Ammonium sulphate
D. Triammonium phosphate

Explanation

To determine which fertilizer cannot replenish nitrogen, we need to analyze the options provided. Here's a step-by-step solution:

### Step 1: Understand the Question
The question asks which fertilizer does not replenish nitrogen. Replenishing nitrogen means providing a source of nitrogen that can be used by plants.

**Hint:** Remember that not all fertilizers contain nitrogen; some may provide other nutrients.

### Step 2: Identify the Fertilizers
We need to look at the options given (though they are not listed in the question, we will assume common fertilizers). Common fertilizers include:
- Urea
- Ammonium sulfate
- Super phosphate of lime
- Calcium nitrate

**Hint:** Familiarize yourself with common fertilizers and their nitrogen content.

### Step 3: Analyze Each Fertilizer
- **Urea:** Contains a high amount of nitrogen (46% N).
- **Ammonium sulfate:** Also contains nitrogen (21% N).
- **Super phosphate of lime:** Primarily provides phosphorus and does not contain nitrogen.
- **Calcium nitrate:** Contains nitrogen (15.5% N).

**Hint:** Look for the primary nutrient each fertilizer provides.

### Step 4: Identify the Correct Answer
From the analysis, we see that **Super phosphate of lime** does not replenish nitrogen, as it primarily provides phosphorus.

**Hint:** Focus on the nutrient composition of fertilizers to determine their function.

### Conclusion
The fertilizer that cannot replenish nitrogen is **Super phosphate of lime**.

**Final Answer:** Super phosphate of lime
