Soils of Western Rajasthan have a high content of
- (a) Aluminum
- (b) Calcium
- (c) Nitrogen
- (d) Phosphorus
Show the answer and explanation
Answer: (b) Calcium
Desert soils are rich in calcium (kankar layers) because low rain doesn’t wash it out.
Why the others are wrong
(a) Aluminium is high in laterite soils.
(c) Desert soils are poor in nitrogen.
(d) Phosphate is moderate, not notably high.
The trap
None.
🔒 Arid soils: high calcium and salts, low nitrogen and humus.
