Q. Which of the following soil is called as a “self – ploughing” soil?

[A] Black Soils

[B] Peaty Soils

[C] Red Soils

[D] Alluvial Soils

Answer: A

Explanation: The black soil is generally clayey, deep and impermeable. They swell and become sticky when wet and shrink when dried.

  • So, during the dry season, these soils develop wide cracks. Thus, there occurs a kind of ‘self-ploughing’.
  • Because of this slow absorption and loss of moisture, the black soil retains the moisture for a very long time, which helps the crops, especially the rain fed ones, to sustain even during the dry season.
