Also known as regur soil, black soil is ideal for growing cotton and is known as black cotton soil. They are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents. [1] The black soils are made up of clayey soil, well known for
Fertile soils such as terra preta show high levels of microorganic activities and other specific characteristics within particular ecosystems. Terra preta zones are generally surrounded by terra comum ([ˈtɛʁɐ koˈmũ, ku-]), or "common soil"; these are infertile soils, mainly acrisols, [6] but also ferralsols and arenosols. [7]
Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [4] Chernozem is very fertile soil and can produce high agricultural yields with its high ...
In this region the main classes of soil are black, brown and bhatori (stony) soil. The volcanic, clay-like soil of the region owes its black colour to the high iron content of the basalt from which it formed. The soil requires less irrigation because of its high capacity for moisture retention.
Most of the region with igneous basaltic rock consists of black soil. These soils have a high clay content, retain moisture and are resistant to erosion, but develop cracks during the dry season. The gneiss peneplain region in the low rainfall areas in the eastern vicinity of the Western Ghats consist of infertile red soil. [32] [37]
In western India, the Kutch region in Gujarat and Koyna in Maharashtra are classified as a Zone IV region (high risk) for earthquakes. The Kutch city of Bhuj was the epicentre of the 2001 Gujarat earthquake , which claimed the lives of more than 1,337 people and injured 166,836 while destroying or damaging near a million homes.

The region is drained by rivers such as Mahanadi, Brahmani, Baitarani, and Subarnarekha. The region consists of fertile red and black soil interspersed with gneiss and sandstone rock formations formed during the paleogene and neogene eras. The sands in the beaches consists of small granites and zircon.
Black soil may refer to: Chernozem, fertile black soils found in eastern Europe, Russia, India and the Canadian prairies; Muck (soil), a soil made up primarily of humus from drained swampland; Vertisol, dark cracking soils with a high clay; Terra preta, "black earth" or soil of the Amazon river basin
