Why is it necessary to level the soil after ploughing?

Explanation

### Step-by-Step Solution:

1. **Understanding Soil Leveling**: After ploughing, the soil is often uneven due to the turning and breaking up of the soil. Leveling the soil helps create a uniform surface.

2. **Improving Soil Quality**: Leveling does not directly change the soil's inherent quality but can enhance its overall condition. A level surface allows for better air circulation and water distribution.

3. **Reducing Soil Erosion**: An even surface minimizes the risk of soil erosion. When the soil is level, water can flow evenly across the surface, reducing the chances of runoff that can wash away topsoil.
