Which practice helps protect soil and crops by creating a wind barrier?

• A. Reduced Stock Density
• B. Check Dams
• C. Shelter Belts
• D. Desertification

Answer: (C)

Creating a wind barrier to protect soil and crops from wind erosion is the key idea. Shelter belts are rows of trees or tall shrubs planted along field edges. They slow the wind near the ground, reducing the distance soil particles can be blown and helping to conserve soil moisture by cutting evaporation. They also create a more favorable microclimate for crops and seedlings. Other practices don’t form a wind barrier: reducing stock density mainly helps with soil compaction from animals; check dams trap runoff to reduce water erosion, not wind; desertification describes land degradation rather than a protective wind-breaking method. So shelter belts are the best fit for guarding soil and crops against wind.
