Which Indian soil term is correctly associated with source or location “found in parts of Kerala, coastal wetlands and other poorly drained depressions”, and also with “it commonly has high humus and may be acidic”?

Correct Answer: Option B — Peaty and Marshy Soil. Peaty and Marshy Soil is correctly identified as found in parts of Kerala, coastal wetlands and other poorly drained depressions. Peaty and Marshy Soil is also associated with it commonly has high humus and may be acidic. Another identifying fact about Peaty and Marshy Soil is that it commonly has high humus and may be acidic. A further exam-relevant fact about Peaty and Marshy Soil is that prolonged saturation slows decomposition of plant material. Why the other options are incorrect: • Option A — Khadar: Khadar is deposited repeatedly along low-lying river floodplains. It is incorrect here because Khadar is instead associated with fresh silt renewal generally makes it highly fertile. • Option C — Bangar: Bangar is located above the active floodplain in many northern plains. It is incorrect here because Bangar is instead associated with calcareous kankar nodules may occur within its profile. • Option D — Alluvial Soil: Alluvial Soil is widespread across the Indo-Gangetic-Brahmaputra plains and coastal deltas. It is incorrect here because Alluvial Soil is instead associated with it commonly contains varying proportions of sand, silt and clay. Exam Takeaway: Connect Peaty and Marshy Soil with “found in parts of Kerala, coastal wetlands and other poorly drained depressions” and “it commonly has high humus and may be acidic” for revision.
