Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This is a geography and agriculture question regarding soil profiles in India and their suitability for major commercial cash crops.

Step 2: Key Formulas and approach:
Identify the physical properties and water-retention requirements of the cotton plant.
Determine which Indian soil type matches these properties.

Step 3: Detailed Explanation:

• Black soil is also widely known as "Regur Soil" or "Black Cotton Soil" because of its high suitability for cotton farming.

• It is formed by the weathering of lava/basaltic rocks in the Deccan Trap region (comprising parts of Maharashtra, Gujarat, and Madhya Pradesh).

• This soil has a high clay content, which gives it an excellent capacity to retain moisture for long periods.

• It is rich in calcium carbonate, magnesium, potash, and lime, which are critical nutrients for cotton growth.

• Alluvial soil is highly fertile but is primarily suited for crops like wheat, rice, and sugarcane, while laterite soil is acidic and suited for plantations like tea and coffee.


Step 4: Final Answer:
Black soil is the most suitable type for cotton cultivation, making Option (C) the correct choice.
