  4. It cannot retain water for long time

Correct answer and explanation

Correct answer: It cannot retain water for long time

Explanation: The correct answer is D. It cannot retain water for long time. Black soil, also called Regur soil, is well known for its high moisture retention capacity due to its clayey nature. It swells when wet and develops deep cracks when dry, helping in aeration. This soil is rich in minerals like calcium carbonate, magnesium, and potash but low in nitrogen and phosphorus. It is mainly found in the Deccan Plateau states like Maharashtra, Madhya Pradesh, Gujarat, and parts of Andhra Pradesh and Tamil Nadu. Black soil is highly suitable for cotton cultivation, which is why it is also called ‘cotton soil.’
