Terrace farming is done on which of the following types of land?

The correct answer is Hills.

Key Points

• Terrace Farming:
  • This is practiced on hill slopes that do not have enough flat terrain for growing crops. Hence, Option 4 is correct.
  • In this, the slopes of the hills are converted into horizontal terraces of regular intervals which allow the cultivation of crops.
  • They also reduce the surface runoff along the slopes and help in preventing soil erosion.

Additional Information

• Contour Bunding
  • In this, a series of checks are put in place across the slope of a hilly surface.
  • The bunds divide the entire slope into numerous smaller segments which help in reducing the runoff along the slopes, ensure greater absorption of rainwater on the slopes thus controlling soil erosion.
  • Sometimes, the bunds can be in the form of retaining walls.
• Contour Ploughing
  • On slopy areas, ploughing of land must be done across the contours, at right angles to the slope.
  • This will prevent the formation of gullies along the slopes which could erode the topsoil through runoff.
  • This also helps in ensuring that the crops along the slopes get adequate water.
