Q. Consider the following statements regarding Alluvial soils in India:

1. Khadar is the new alluvium and is deposited by floods annually.
2. Bhangar represents a system of older alluvium, deposited away from the flood plains.
3. Only Bhangar soils contain calcareous concretions.
4. The sand content decreases from the east to west.

Which of the above statements is / are correct?
Answer: Only 1 and 2
Notes: Khadar is indeed the newer alluvium deposited annually by floods, while Bhangar is older alluvium away from recent floods. Both Khadar and Bhangar may contain calcareous concretions (kankars), not just Bhangar. Sand content decreases generally from west to east, not east to west. Thus, only statements 1 and 2 are correct.
