Question

What is black soil a type of?

Answer 1

Hint: Soil is made up of organic matter, minerals, gases, liquids, and organisms, all of which work together to support life. The pedosphere, or body of soil on Earth, serves four important functions: it serves as a medium for plant growth. as a means of storing, supplying, and purifying water

Complete answer:
Cotton soil is a type of black soil. As cotton is the most important crop grown on these soils, they are also known as regur (from the Telugu word Reguda) and black cotton soils. Several theories have been proposed to explain the origin of this group of soils, but most pedologists believe that they were formed as a result of the solidification of lava that was spread over large areas during volcanic activity in the Deccan Plateau, thousands of years ago.
The Deccan and Rajmahal traps, as well as ferruginous gneisses and schists found in Tamil Nadu, account for the majority of black soils. The former is sufficiently deep, whereas the latter is mostly shallow.
Black soil's characteristics:
Most of the Deccan Plateau is covered in black soil, including Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, and parts of Tamil Nadu.
Clayey, deep, and impermeable soils characterize black soils.
The black soils are chemically rich in lime, iron, magnesia, and alumina.
They also have potash in them. However, they are deficient in phosphorus, nitrogen, and organic matter.
The black soil is extremely water-retentive. When wet during the rainy season, it swells dramatically and becomes sticky.

Thus, Cotton soil is a type of black soil.

Note:
The origin of black cotton soils is attributed in some parts of Gujarat and Tamil Nadu to old lagoons where rivers deposited materials brought down from the interior of the Peninsula covered in lava.
