Question

list the main characteristics of arid soil

Answer 1

Arid soil is widely found in Western Rajasthan.
(i) The soil ranges red to brown in colour.
(ii) The soils contain considerable amount of soluble salts.
(iii) The soils contain a low percentage of organic matter due to dry climate and absence of vegetation.
(iv) The soil is alkaline in nature as there is no rainfall to wash soluble salts.
(v) The lower horizon of the soil is occupied by ‘kankar’ because of the increasing calcium content downwards. The ‘kankar’ layer formations in the bottom horizons restrict the infiltration of water.
(vi) The soils are infertile but with irrigation and
fertilizers, the drought resistant and salt tolerant dry crops such as barley, cotton, wheat, millets, maize, pulses, etc., are grown.

In some areas the salt content is very high and common salt is obtained by evaporating the water.

->>

Due to the dry climate, high temperature, evaporation is faster and the soil lacks humus and moisture.

->>

The lower horizons of the soil are occupied by Kankar because of the increasing calcium content downwards.
