Soil is the reservoir of essential elements except:

Options

A. Phosporus
B. Sulphur
C. Carbon
D. Calcium

Answer

To solve the question "Soil is the reservoir of essential elements except:", we can follow these steps:

### Step 1: Understand the Question
The question asks us to identify which element is not found in the soil, among the options provided.

### Step 2: Analyze the Options
We need to evaluate each option to determine whether it is typically found in soil or not.

### Step 3: Evaluate Each Element
1. **Phosphorus**: Phosphorus is derived from rocks through weathering and is an essential nutrient for plants. It is indeed present in the soil.

2. **Sulfur**: Sulfur is also found in soil as it comes from various sources, including the decomposition of organic matter and minerals. Therefore, sulfur is present in the soil.

3. **Calcium**: Calcium is commonly found in the form of calcium salts in the soil and is essential for plant growth. Thus, calcium is present in the soil.

4. **Carbon**: Carbon is primarily found in the atmosphere and oceans, and while it is essential for life, it is not typically stored in the soil as a mineral. Instead, it exists in organic forms (like organic matter) and in fossil fuels, but not as a mineral element in soil.

### Step 4: Identify the Correct Answer
Based on the evaluation, the only element that is not found in soil is **Carbon**.

### Final Answer
Soil is the reservoir of essential elements except **Carbon**.
