Soil porosity is the maximum in

Options

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

Answer

To determine which type of soil has the maximum porosity, we need to understand the concept of soil porosity and how it relates to the size of soil particles.

### Step-by-Step Solution:

1. **Define Soil Porosity**:
- Soil porosity refers to the amount of pore space available in the soil. It is the ratio of the volume of voids (pores) to the total volume of soil.

2. **Understand Particle Size**:
- The size of soil particles plays a crucial role in determining porosity. Generally, smaller particles create more pore spaces compared to larger particles.

3. **Analyze Different Soil Types**:
- **Sandy Soil**: Composed of larger particles, which means it has fewer pores and thus lower porosity.
- **Clay Soil**: Made up of very fine particles, leading to a higher number of pores and thus higher porosity.
- **Silt**: Has intermediate particle sizes, which means it has moderate porosity, but not as high as clay.
- **Loam**: A mixture of sand, silt, and clay, which gives it a balanced porosity, but still not as high as pure clay.

4. **Conclusion**:
- Among the options provided (sandy soil, clay soil, silt, and loam), clay soil has the maximum porosity due to its composition of many small particles that create numerous pore spaces.

### Final Answer:
- **Clay soil has the maximum porosity.**
