Soils in India Questions and Answers

Correct Answer: Option D — Bangar. Bangar is correctly identified as it is generally less frequently renewed by floods than khadar. Bangar is also associated with the older alluvium of elevated river terraces. Another identifying fact about Bangar is that calcareous kankar nodules may occur within its profile. A further exam-relevant fact about Bangar is that it is generally less frequently renewed by floods than khadar. Why the other options are incorrect: • Option A — Alluvial Soil: Alluvial Soil is it supports crops such as rice, wheat, sugarcane and jute. It is incorrect here because Alluvial Soil is instead associated with a transported soil deposited mainly by rivers. • Option B — Black Soil: Black Soil is its high moisture retention makes it especially suitable for cotton. It is incorrect here because Black Soil is instead associated with a clay-rich soil also called regur or black cotton soil. • Option C — Red and Yellow Soil: Red and Yellow Soil is it is generally deficient in nitrogen, phosphorus and humus. It is incorrect here because Red and Yellow Soil is instead associated with a soil whose colour is linked mainly to iron compounds. Exam Takeaway: Connect Bangar with “it is generally less frequently renewed by floods than khadar” and “the older alluvium of elevated river terraces” for revision.

Correct Answer: Option D — Khadar. Khadar is correctly identified as it is more frequently flooded than the older alluvial terraces. Khadar is also associated with the newer alluvium of active floodplains. Another identifying fact about Khadar is that fresh silt renewal generally makes it highly fertile.
