3. Regur Soil
4. Alluvial soil
5. None of the above

Answer 1

Correct Answer - Option 2 : Red Soil

The correct answer is Red Soil.

• Red Soil:-
  • ​Red soil develops reddish colour due to the diffusion of iron in crystalline and metamorphic rocks.
  • It looks yellow in a hydrated form.
  • It is highly porous and fertile when they are fine-grained and deep.
  • This soil is deficient in nitrogen, humus, phosphoric acid, magnesium, and lime but fairly rich in potash, with its pH ranging from neutral to acidic.
  • Cotton, wheat, rice, beans, millets, tobacco, oilseeds, potatoes, and fruits are some of the appropriate crops for red soils.
  • Red soil develops on crystalline igneous rocks in areas of low rainfall in the eastern and southern parts of the Deccan plateau.
  • They are also found in parts of Orissa, Chhattisgarh, southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats.
