Black Soils:

Black soil is black in colour and is also known as regular soil.
Black soil is ideal for growing cotton and is also known as black cotton soil.
It is believed that climatic conditions along with the parent rock material are the important factors for the formation of black soil.
This type of soil is typical of the Deccan trap (Basalt) region spread over northwest Deccan plateau and is made up of lava flows.
They cover the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh and extend in the south east direction along the Godavari and the Krishna valleys.
The black soil is made up of extremely fine i.e. clayey material.
They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents.
They develop deep cracks during hot weather, which helps in the proper aeration of the soil. These soils are sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.
