2.The lower horizons of the soil are occupied by Kankar.
3.Arid soils range from red to brown in colour.
How many of the statements given above are correct?
Answer: C
Notes:
Explanation: Arid soils range from red to brown in colour. They are generally sandy in texture and saline in nature.
- In some areas, the salt content is high, and common salt is obtained by evaporating the water.
- Due to the dry climate, high temperature, evaporation is faster and the soil lacks humus and moisture.
- The lower horizons of the soil are occupied by Kankar because of the increasing calcium content downwards.
- The Kankar layer formations in the bottom horizons restrict the infiltration of water.
