Question

Rows of trees planted in the coastal areas to check the wind movement are called intercropping. State whether the given statement is true or false. If true, give the reasons.

Answer 1

Answer: The given statement is false. To protect the top soil from erosion due to wind movement, shelter belts are used; it is nothing but planting trees in rows. This method is used in dry and coastal regions.

• Terrace farming reduces soil erosion and surface runoff.
• In Terrace farming flat surfaces are made for growing crops by making terraces or flat steps.
• To protect the soil from getting washed away due to rains, different crops are grown in alternate rows and at different times. This method of protecting soil is known as intercropping.
• To slow down the flow of water and prevent soil loss, rocks are piled up, this is known as rock dam.
• Soil moisture can be retained by covering bare ground between plants with a layer of organic matter like straw. This is known as mulching.
• Soil, grass, stones are used as a barrier along contours, this is known as a contour barrier. Trenches are made in front of the barriers to collect water.
