The Soil found in the Deccan Plateau is Black Soil. It is also known as the Deccan Trap. The igneous rocks from which the soil is formed give it its distinctive black color. These igneous rocks are volcanic in origin, and the soil is the result of denudation over time. Cotton is abundantly grown because the black soil is extremely fertile. Because of the traditional method of growing cotton, black soil is also known as black cotton soil.

Soil Found in the Deccan Plateau

Black soil is derivated from trap lava and hence, has its signature black appearance. It can be found in the states of Gujarat, Karnataka, Maharashtra, and Madhya Pradesh on the Deccan lava and the Malwa Plateau. These areas experience moderate rainfall.

Because black soil contains a high concentration of clay, it develops wide and deep cracks during the summer. However, its iron-rich granular structure prevents it from being prone to water and wind erosion. It retains a lot of moisture and, as a result, responds well to irrigation.

  • Mineral soils having a black surface horizon that is at least 25 cm deep and rich in organic carbon are known as black soils.
  • Black soils are divided into the first and second groups.
  • The distinctions between the categories are made to acknowledge the higher value and hence greater need for the protection of specific soils (Category 1) while encompassing a larger variety of soils under the overall concept of black soil (Category 2).
  • Some minerals found in black soil include lime, iron, calcium, magnesium, potash, and aluminum.
