Question

Which of the following is/are methods of checking soil erosion?
$1$. Strip cropping
$2$. Contour ploughing
$3$. Use of irrigation and fertilisers
$4$. Terrace farming.

• A. $1$ and $2$
• B. $3$ and $4$
• C. $2,3$ and $4$
• D. $1,2,$ and $4$

Answer 1

The correct option is D $1,2,$ and $4$

• Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing.
• Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion.
• Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. This method is known as strip cropping. Strip cropping method reduce the soil erosion
