The best soil for growing paddy is the one which has :

Options

A. low percolation rate of water
B. high percolation rate of water
C. moderate percolation rate of water
D. zero percolation rate of water

Answer

To determine the best soil for growing paddy, we need to consider the characteristics of different types of soil. Here’s a step-by-step solution:

### Step 1: Understand the requirements for growing paddy
Paddy, or rice, requires specific soil conditions to thrive. The ideal soil should have certain properties that support its growth.

### Step 2: Identify soil particle size
Paddy grows best in soil with smaller particles. This is because smaller particles create a denser soil structure, which is beneficial for water retention.

### Step 3: Consider water holding capacity
The soil should have a high water holding capacity. This is crucial for paddy as it is typically grown in flooded conditions. The ability of soil to retain water is essential for the growth of paddy plants.

### Step 4: Analyze percolation rate
Percolation refers to the movement of water through soil. For paddy cultivation, a low percolation rate is desirable. This means that water does not drain away quickly, allowing the soil to remain saturated for longer periods.

### Step 5: Determine the type of soil
Based on the characteristics discussed:
- **Clay soil** has small particles, high water holding capacity, and low percolation rate. This makes it the best choice for growing paddy.
- **Sandy soil** has high percolation rates and does not retain water well, making it unsuitable for paddy.
- **Loamy soil** has moderate properties but is not as ideal as clay for paddy.
- **Silt soil** has zero percolation rate, which is not suitable for paddy cultivation either.

### Conclusion
The best soil for growing paddy is clay soil, as it possesses the necessary characteristics of small particle size, high water retention, and low percolation rate.

### Final Answer
The best soil for growing paddy is the one which has low percolation rate of water, which is found in clay soil.
