Answer 2

Among the following practices kul is not used to prevent soil erosion. (Option 2)

• Kul is a method for water conservation that involves a lot of soil erosion.
• This is because, kuls are long channels which carry water from glaciers to the regions of requirements (like villages).
• Bunding is a practice of barrier construction for various purposes, and this prevents water run-off as well as filters water passing through it and hence helps reduce soil erosion.
• Mulching is the practice of planting trees, shrubs, grasses, etc. or covering plain or recently planted soils with wood, gravel, hay, straw, etc. to prevent soil erosion.
• Soil moisture retains soil density as well as increases its stickiness which will prevent it from eroding away.
