Which of the following statement is not true about Black Soils in India?

Question

Accepted Answer

Option 1 is the correct answer because the statement "This soil is spread in 10.6 percent of the total geographical area of the country" is not true about Black Soils in India. Black soils actually cover approximately 16-19% of the total geographical area of India, primarily in the Deccan plateau. The 10.6% figure is inaccurate and therefore makes this statement false.

Now, let's explain why the other options are incorrect:

*   **Option 2: The Black colour of this soil is due to presence of titaniferous magnetite.** This statement is true. The presence of titaniferous magnetite, along with iron and aluminum compounds, contributes to the characteristic black color of these soils. Therefore, this option is incorrect because the question asks for the *false* statement.

*   **Option 3: This soil is highly retentive of moisture.** This statement is also true. Black soils are known for their high moisture retention capacity. This is due to their clayey nature, which allows them to hold water for extended periods. Therefore, this option is incorrect.

*   **Option 4: It becomes sticky in rainy season.** This statement is true. Due to the high clay content, black soils become sticky and difficult to work with during the rainy season. Therefore, this option is incorrect.

In conclusion, only Option 1 presents a false statement about Black Soils in India, making it the correct answer. The other options accurately describe characteristics of black soil.
