Question

mention any four features of black soil​

Answer 1

The following are five important characteristics of Black soil:

1. It is fine textured and clayey in nature.
2. It has high amounts of lime, iron, magnesium and generally low quantities of phosphorus, nitrogen and organic matter.
3. It is black in colour since it is formed from weathered lava rocks.
4. It has up to 50% clay content and therefore is highly retentive of water. Because of the high clay content, these soils expand when wet and become difficult to plough through. During the dry season, these soils shrink and develop big cracks which help in the circulation of air.
5. The soil is extremely fertile in most of the places where it is found.

This answer has all the basic points related to black soil.
