Question

Name the states where black soil is found.

Answer 1

Hint:
Black soil is referred to as regur, and has come from the Telugu word reguda and popularly known as black cotton soil because cotton is the most traditional crop in the areas where it is found.

Black soils are mineral soils enriched with organic carbon. It is at least 25 cm deep with a black surface horizon.

Complete answer:
In India, among the in situ soils, the black soil is found in the lava-covered areas. During the dry season, the black soils develop wide cracks because of their clay content. The soil has an iron-rich granular structure, which makes it resistant to water and wind erosion.

Black soil is rich in potassium, calcium, and magnesium, and it has very poor nitrogen content. The crops which grow very well in this type of soil are jowar, ragi, maize, cotton, tobacco, oil, chilly, and seeds. This soil is clayey and has the ability to hold a lot of moisture, and it becomes sticky in the rainy season. Wheat, linseeds, millets, and cotton can be grown in the Black soil.

Black soils are the derivatives of trap layer and are found in the states of Karnataka, Gujarat, Maharashtra, and Madhya Pradesh of Deccan lava plateau and the Malwa plateau as these places have moderate rainfall and underlying basaltic rock.

Note:
The black soil is very poor in humus, but it is highly moisture-retentive, which responds well to irrigation.

The soil is found in peripheral tracts, where the tracts are underlying basalt are shifted by fluvial processes.
