Question

A. Clay content of black soils ranges from 30-80%.
B. Black soils are developed on basalt or alluvium derived basaltic rock.
C. Black soils exhibit eluviation and/or illuviation process.
D. Black soils have high bulk density.
Choose the correct answer from the options given below:

• A. A, B and C only
• B. A, B and D only
• C. A, C and D only
• D. B, C and D only

Hint:

Black soil: high clay, high bulk density.
Developed on basalt.
No eluviation-illuviation.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Black soils have specific characteristics.
We need to identify the correct statements about black soils.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the properties of black soils.

Step 3: Detailed Explanation:
Clay content of black soils ranges from 30-80%.
This is correct.
Black soils are developed on basalt or alluvium derived from basalt.
This is correct.
Black soils do not exhibit eluviation and illuviation.
They have a uniform profile.
Thus, C is incorrect.
Black soils have high bulk density.
This is correct.
Thus, A, B, and D are correct.

Step 4: Final Answer:
The correct statements are A, B, and D.
Hence, the correct option is (B).
