How Is Black Soil Formed?

Black soil is formed by the weathering or breaking of igneous rocks and also by the cooling or solidification of lava from the volcano eruption. Therefore, it is also called as the lava soil. As per the name, black soil is black in colour and is most abundantly found in Chhattisgarh, Madhya Pradesh, Maharashtra and in some southern parts of India, including the Godavari and near to the Krishna valleys.

Black soil are rich in Calcium, Carbonate, Potash and hold moisture, hence it is found sticky when it is wet and cracks when it is dry. As discussed, back soil is formed from the volcano eruption, which is very much fertile and best suitable for intensive agriculture.

This soil is black in colour mainly because they are formed by weathering of lava rocks and are high iron, alumina and magnesia content and is best suitable for cottoncrop production. Because of its fertility and high moisture-retentive, black soil is widely used for cultivating several other crops including linseed, castor, millets, sunflower, sugarcane, etc.
