Explanation:

Black soil is not found in Punjab. Black soil is a  group of soils characterised by dark grey to black colour with high clay content.
They are neutral to slightly alkaline in reaction. Deep cracks develop during summer, the depth of the soil varies from less than a meter to several meters. Poor free drainage results in the soils, base exchange is high with high pH and rich in lime and potash. Major black soils are found in Maharastra, Madhyapradesh, Gujarat and Tamilnadu.

Cotton is most favourable crop to be grown in these soils. These soils are classified in the order 'Entisols', ' Inceptisols' and ' vertisols'.
