Question 1
Applied ConceptA farmer in Rajasthan wants to cultivate crops on his arid land. With reference to the characteristics of arid soils, advise him on the steps he should take to make the land productive.
- Arid soils in Rajasthan are sandy, saline, and deficient in humus and moisture; the kankar layer in the lower horizons restricts water infiltration, making natural cultivation difficult.
- The farmer should invest in proper irrigation infrastructure — the chapter notes that arid soils can become cultivable after proper irrigation, as demonstrated in western Rajasthan.
- He should also adopt soil improvement measures such as adding organic matter to build humus content, breaking the kankar layer where possible, and using drought-resistant crop varieties suited to sandy soils.
