Question

Which of the following is used for soil conservation?
(a) mulching (b) shelter belt
(c) contour ploughing
(d) all of these

Answer 1

Answer:

d. All of these.

Explanation:

The correct option is d, all of these.

The reason is that all the three practices mentioned here, mulching, shelter belt, and contour plowing are all used for soil conservation as:

• Instead of arranging crop rows up and down a slope, contour plowing follows the contours of hills and slopes.
• A windbreak is a planting that typically consists of one or more rows of trees or shrubs that are placed so as to offer protection from the wind and prevent soil erosion. On farms, they are frequently planted as hedgerows along the boundaries of fields.
• Spreading a layer of material on the ground around plants to protect their roots from heat, cold, or drought or to keep the fruit clean is a well-known horticultural practice known as mulching.
• Hence, all option D is the correct answer.
