Soil A has a high percolation rate of water whereas soil B has a low percolation rate of water. Which of the two soils, A or B, is most suitable for growing paddy (rice crop)? Why?

Answer

To determine which soil is more suitable for growing paddy (rice crop), we need to analyze the characteristics of both soils based on their percolation rates.

### Step-by-Step Solution:

1. **Understanding Percolation Rate**:
- Percolation rate refers to the speed at which water moves through soil. A high percolation rate means water drains quickly, while a low percolation rate means water drains slowly.

2. **Characteristics of Soil A**:
- Soil A has a high percolation rate. This type of soil is typically sandy, which has larger particles and allows water to pass through quickly.

3. **Characteristics of Soil B**:
- Soil B has a low percolation rate. This type of soil is usually clayey, which has smaller particles that hold water and do not allow it to drain quickly.

4. **Water Requirement for Paddy**:
- Paddy (rice) crops require a lot of water and thrive in conditions where water can stand in the fields. This means that the soil should retain water rather than allow it to drain away quickly.

5. **Conclusion**:
- Given that soil B has a low percolation rate, it is more suitable for growing paddy because it retains water, creating the necessary conditions for rice cultivation. In contrast, soil A, with its high percolation rate, would not hold water well, making it unsuitable for paddy.

### Final Answer:
Soil B is most suitable for growing paddy (rice crop) because it has a low percolation rate, which allows it to retain water, essential for the growth of rice.
