Question: Shelter belt is a method of
Options:
water conservation
soil formation
plantation
soil conservation
Shelterbelts:
🌳 In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
🌳 Shelterbelts are rows of trees, usually along fence lines.
🌳 They are planted mainly to protect animals or crops from cold winds, but also to give shade in hot weather.
🌳 In regions such as Canterbury where there is a lot of cultivated land, shelterbelts also reduce wind erosion.
🌳 Shelter belts are a series of trees or shrubs grown in a form of horizontal lines adjacent to the field.
🌳 A series of trees planted to grow in the edges of a field in order to protect the fields from high-speed winds.
🏆 Hence, option 4 is the correct answer.
🌾 Other methods of soil conservation:
🌱 Mulching: The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.
🌱 Contour barriers: Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.
🌱 Rock dam: Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
🌱 Terrace farming: These are made on steep slopes so that flat surfaces are available to grow crops. They can reduce surface run-off and soil erosion.
🌱 Intercropping: Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
🌱 Contour ploughing: Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.
