Which Indian soil term is correctly associated with source or location “occurs in arid tracts, poorly drained plains and some coastal areas”, and also with “reh, usar and kallar are regional names associated with salt-affected land”?

Correct Answer: Option B — Saline and Alkaline Soil. Saline and Alkaline Soil is correctly identified as occurs in arid tracts, poorly drained plains and some coastal areas. Saline and Alkaline Soil is also associated with reh, usar and kallar are regional names associated with salt-affected land. Another identifying fact about Saline and Alkaline Soil is that reh, usar and kallar are regional names associated with salt-affected land. A further exam-relevant fact about Saline and Alkaline Soil is that drainage, leaching and gypsum treatment can aid reclamation where appropriate. Why the other options are incorrect: • Option A — Peaty and Marshy Soil: Peaty and Marshy Soil is found in parts of Kerala, coastal wetlands and other poorly drained depressions. It is incorrect here because Peaty and Marshy Soil is instead associated with it commonly has high humus and may be acidic. • Option C — 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 D — 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. Exam Takeaway: Connect Saline and Alkaline Soil with “occurs in arid tracts, poorly drained plains and some coastal areas” and “reh, usar and kallar are regional names associated with salt-affected land” for revision.
