Which one of the following soil types of India is rendered infertile by the presence of excess Iron?

  1. Desert sand

  2. Alluvial

  3. Black soils

  4. Laterite
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Lateritic soil types of India are rendered infertile by the presence of excess iron. Laterite soils are those soils that are found in the areas which receive high rainfall and have a very high temperature. This results in less humus content in the soil. Hence, they are not fertile soil and are not suitable for cultivation.
