Arid soils:
i. Arid soils range from red to brown in colour. They are generally sandy and alkaline.
ii. In some areas, salt content is so high that common salt is obtained by evaporating the saline water. Due to dry climate, high temperature and accelerated evaporation, the lack of moisture and humus content is normal.
iii. Lower horizons of soils are occupied by kankar because of increase calcium content downward.
iv. Arid soils are characteristically developed in western Rajasthan, which exhibits characteristic desert topography.
v. These soils are poor and contain less humus and organic matter. They are generally used for the cultivation of coarse grains like jowar, bajra, ragi etc. and oil seeds.
