Which Indian soil term is correctly associated with classification or identity “an organic-rich soil formed in waterlogged conditions”, and also with “found in parts of Kerala, coastal wetlands and other poorly drained depressions”?

Correct Answer: Option A — Peaty and Marshy Soil. Peaty and Marshy Soil is correctly identified as an organic-rich soil formed in waterlogged conditions. Peaty and Marshy Soil is also associated with found in parts of Kerala, coastal wetlands and other poorly drained depressions. 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 B — Khadar: Khadar is the newer alluvium of active floodplains. It is incorrect here because Khadar is instead associated with deposited repeatedly along low-lying river floodplains. • Option C — Bangar: Bangar is the older alluvium of elevated river terraces. It is incorrect here because Bangar is instead associated with located above the active floodplain in many northern plains. • Option D — Alluvial Soil: Alluvial Soil is a transported soil deposited mainly by rivers. It is incorrect here because Alluvial Soil is instead associated with widespread across the Indo-Gangetic-Brahmaputra plains and coastal deltas. Exam Takeaway: Connect Peaty and Marshy Soil with “an organic-rich soil formed in waterlogged conditions” and “found in parts of Kerala, coastal wetlands and other poorly drained depressions” for revision.
