Consider the following:

  1. Strip-cropping
  2. Contour bunding
  3. No-till farming

Which of the above is/are used for soil conservation?

Answer: [D] 1, 2 & 3

Contour bunding is the farming practices of plowing across a slope following its elevation contour lines. These contour lines across a slope create water blockage and thus prevents heavy water run-off; which is a major cause of soil erosion. The water break also allows more time for the water to settle into the soil. Strip cropping is a method of farming which involves cultivating on a field which has been divided into long, narrow strips with alternate crop rotation system. It is used when a slope is too steep or when there is no alternative method of preventing soil erosion. No till farming is a method of farming where soil is not disturbed through is a way of growing crops or pasture from year to year without disturbing the soil through tillage.
