Confusion Points

📌 Other Methods of Soil Conservation:
🌱 Mulching:
→ Bare ground between plants is covered with organic matter like straw, helping to retain soil moisture.

🌿 Contour Barriers:
→ Stones, grass, or soil are used to build barriers along contours, with trenches in front of the barriers to collect water.

🪨 Rock Dam:
→ Rocks are piled up to slow the flow of water, preventing gullies and soil loss.

🌾 Terrace Farming:
→ Flat surfaces are created on steep slopes to grow crops, reducing surface runoff and soil erosion.

🌾 Intercropping:
→ Different crops are grown in alternate rows, sown at different times to protect soil from rain wash.

🌄 Contour Ploughing:
→ Ploughing parallel to the contours of a hill slope forms a natural barrier, slowing water flow and conserving soil.
