In which one of the following soils, the salt content is so high that common salt is obtained by evaporating the saline water in some areas?

Peaty soil
Alluvial soil
Laterite soil
Arid soil

UPSC CAPF – 2021
Arid soils are characteristic of dry regions with high evaporation. Due to capillary action, salts from lower layers are brought to the surface, leading to high salinity. In areas with saline arid soils, particularly those with shallow groundwater or proximity to saline water sources, the salt content can be so high that common salt can be obtained by evaporating the saline water collected in pans. This practice is common in Rann of Kutch, which has characteristics of arid soil.
– Arid soils are found in dry climates.
– High evaporation in arid regions leads to salt accumulation on the surface.
– Saline arid soils can be a source of common salt through evaporation.
Peaty soils are found in humid areas with waterlogged conditions and high organic matter. Alluvial soils are deposited by rivers and are generally fertile, although they can become saline in dry areas with poor drainage. Laterite soils are formed in tropical regions through intense leaching and are rich in iron and aluminum oxides, typically acidic and not saline.
