Regur soil is black in colour and it is also known as ‘black soils’.
They are perfect for growing cotton, they are also called cotton soils
These soils are most characteristic of the Deccan trap (Basalt) region , spread over the north-west Deccan plateau and are made up of lava flows.
They cover the plateaus of Maharashtra, Saurashtra, Malwa and southern Madhya Pradesh and continue eastwards in the south, along the Godavari River and Krishna River Valleys
Owing to the high proportion of clay, Regur soils are sticky when wet and consequently becomes difficult to plough
They are well-known for their ability to retain moisture
They are prosperous in soil nutrients, like calcium carbonate, magnesium carbonate, potash and lime
They are usually poor in phosphoric content
They develop thick fissures in the field during hot weather
This helps in their ventilation.
This soil is viscous and unmanageable to work unless tilled without delay, after the first or pre-monsoon showers.
