To maintain control over wind erosion, soil should be kept in what condition?

1. Dry

2. Moist

3. Loose

4. Compact

The correct answer is: Moist

Maintaining soil in a moist condition is essential for controlling wind erosion. When soil is kept moist, it helps to bind the soil particles together, reducing the likelihood that they will be lifted into the air by strong winds. Moisture creates a cohesive environment in which soil particles stick together, which is essential for preventing erosion. In contrast, dry soil becomes loose and more easily disturbed by wind, leading to greater erosion risk. Loose soil is also more prone to being picked up and carried away by wind. Meanwhile, compact soil can lead to poor water infiltration and root growth, but it does not address the wind erosion concern effectively. Therefore, keeping the soil moist is a best practice for managing erosion caused by wind.
