Arid:

The three main characteristics of arid soil of India are

(i) Arid soils are the soils of desert or semi-desert regions and colours varies from red to brown.

(ii) The soil has sandy texture and salinity. As precipitation is very low the temperature is high and evaporation is faster making it lack in moisture and humus.

(iii) The calcium content increase downward and forms kankar layers downward and sometimes the kankar layer in the bottom layers restrict the infiltration of water. Sometimes, after irrigation its productivity is increased and it becomes suitable for cultivation.

Black Soil :

Three characteristics of black soil which make the soil fertile are:

(i) It is fine textured and clayey in nature.

(ii) It is moisture retentive.

(iii) It is black in colour as it is formed from weathered lava rocks.

Alluvial Soil:

Major characteristics of alluvial soil are:

i) It is formed by the deposition of the river load as it flows from its upper to its lower course.

ii) It is light and porous, therefore easily tillable.
