Consider the following:

  1. Contour bunding
  2. Monocropping 
  3. Crop rotation

  Which of the above help in soil conservation?

Answer: [C] 1 & 3 Only

Crop rotation reduces soil erosion by wind and water and increases soil fertility.Contour bunding is the farming practice of plowing and/or planting across a slope following its elevation contour lines. Monocropping is the agricultural practice of growing a single crop year after year on the same land. Monocropping is responsible for soil erosion.
