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.
