Question

Which soil is most suitable for growing cotton?

• A. Sandy soil
• B. Alluvial soil
• C. Black soil
• D. Laterite soil

Hint:

Black soil is also called regur soil and is popularly known as cotton soil because it provides ideal moisture and nutrient conditions for cotton cultivation.

Answer 1

The Correct Option is C

Step 1: Understanding soil requirements of cotton.
Cotton is a major commercial crop that requires specific soil conditions for healthy growth. The soil should have good moisture retention capacity, proper aeration, and adequate nutrients to support the crop during its growing period.

Step 2: Characteristics of black soil.
Black soil, also known as regur soil, is rich in clay and has a high capacity to retain moisture. It contains essential nutrients such as calcium carbonate, magnesium, potash, and lime. This soil swells when wet and shrinks when dry, helping maintain soil moisture for longer periods.

Step 3: Comparison with other soil types.

• (A) Sandy soil: Sandy soil drains water quickly and has poor nutrient retention, making it less suitable for cotton cultivation.
• (B) Alluvial soil: Although fertile and suitable for many crops, it does not retain moisture as effectively as black soil for cotton growth.
• (C) Black soil: Correct. Its high moisture retention and nutrient content make it ideal for cotton cultivation.
• (D) Laterite soil: Laterite soil is generally acidic and low in fertility, making it less suitable for cotton.

Step 4: Conclusion.
Because of its high moisture retention capacity and nutrient-rich composition, black soil is the most suitable soil type for growing cotton. Final Answer:} Black soil.
