The black cotton soils are also called 'Regur'
They are highly moisture retentive
They are rich in lime
These soils have less clay factor and hence can support a wide variety of crops and vegetables

Answer 1

The correct answer is These soils have less clay factor and hence can support a wide variety of crops and vegetables.

Key Points

The black cotton soils, also known as 'Regur', are found in the Deccan Plateau region.
These soils are characterized by their high moisture retention capacity due to the high clay content.
They are rich in lime, iron, magnesium, and alumina, which are essential for plant growth.
The high clay content makes these soils sticky when wet and hard when dry, which can limit the variety of crops that can be grown compared to soils with less clay.

Additional Information

Regur Soil:
- Derived from the lava rock formations in the Deccan Plateau.
- Known for its fertility, particularly for cotton cultivation.
Composition:
- High in clay, making it capable of retaining water for longer periods.
- Rich in calcium carbonate, magnesium, potash, and lime.
Challenges:
- Heavy and difficult to work with when wet.
- Forms deep cracks in dry conditions, affecting soil structure and crop roots.
Uses:
- Primarily used for growing cotton, hence the name 'black cotton soil'.
- Also suitable for crops like sorghum, millets, pulses, and maize.
