Question

In Rajasthan, both granite and sandstone give birth to which kind of soil under arid climate?
(A) Alluvium
(B) Sandy soil
(C) Red soil
(D) None of these

Answer 1

Hint: Soil is light, warm, dry and has a tendency to be acidic and low in nutrients. Sandy soils are frequently recognised as mild soils due to their excessive percentage of sand and little clay (clay weighs extra than sand). These soils have speedy water drainage and are convenient to work with.

Complete answer:
Silty and sandy soils are most inclined to water erosion, especially in areas with excessive rainfall and the place the floor slopes. Fields very prone to erosion regularly have shallow channels or rills, or even large deeper gullies, after heavy rain. Surface water runoff occurs when the depth of rainfall is so exquisite that all the water can't soak into the soil. Livestock management can additionally have an effect on the quantity of soil erosion and runoff in grassland. Grazing with giant numbers of inventory in moist prerequisites can motivate serious poaching of the soil and compaction in the topsoil which can lead to an improved hazard of runoff.

Galanga requires fertile sandy soil and a heat-humid climate. It prospers properly up to an elevation of about 1500 m above MSL. A well-distributed annual rainfall of 1500–3000 mm is required at some point of the developing length and dry spells at some point of land guidance and harvesting. The species is propagated by means of rhizome fragments. Mother rhizomes are top of the line in contrast to fingers. The rhizome bits are planted on beds of 1–2 m width and 25 cm top at a spacing of 40–60 cm2.

Hence, the correct answer is option ‘B’.

Note: In Rajasthan, both granite and sandstone provide beginning to sandy soil. Sandy soils have low moisture storage. High evaporation and low ability restrict the availability of rainwater for plant use. As Rajasthan is commonly protected by means of desert, it has sandy soil to the most extent..
