Soil porosity is the maximum in

Options

A. Sandy soil
B. Clay soil
C. Loam soil
D. Loam

Answer

To determine which type of soil has the maximum porosity, we need to understand what soil porosity is and how it varies among different soil types.

### Step-by-Step Solution:

1. **Understanding Soil Porosity**:
- Soil porosity refers to the volume of soil voids or gaps that can be filled with water or air. It is an important property of soil that affects water retention, drainage, and aeration.

2. **Factors Affecting Soil Porosity**:
- The porosity of soil primarily depends on two factors:
- **Particle Size**: Smaller particles create more voids.
- **Soil Aggregation**: The arrangement of soil particles can influence the amount of space between them.

3. **Comparison of Soil Types**:
- **Sandy Soil**:
- Composed of larger particles, sandy soil has fewer voids and lower porosity.
- **Clay Soil**:
- Made up of very small particles, clay soil has a high number of tiny voids, leading to higher porosity.
- **Loam Soil**:
- A mixture of sand, silt, and clay, loam has moderate porosity, which is generally less than clay but more than sandy soil.

4. **Conclusion**:
- Among the soil types mentioned (sandy, clay, and loam), clay soil has the maximum porosity due to its small particle size and the large number of voids it contains.

5. **Final Answer**:
- The correct answer is **clay soil**.
