Which of the following soils has the highest water-retaining capacity?

Correct option is B

The correct answer is: (B) Black soil

Explanation:

• Black soil (also known as Regur soil) has a high clay content which gives it a high water-retaining capacity.
• This makes it suitable for crops like cotton that require more moisture.

Information Booster:

• Black soil is formed by the weathering of basalt rocks.
• It is commonly found in the Deccan Plateau region (Maharashtra, Madhya Pradesh, Gujarat).
• Known for its fertility and moisture retention even during dry seasons.
• It swells when wet and develops cracks when dry.
• Rich in lime, iron, magnesia, and alumina.

Additional Information:

• Red soil: Low in humus and nutrients, porous, with poor water-holding capacity.
• Desert soil: Sandy and dry with minimal moisture retention.
• Alluvial soil: Fertile and suitable for agriculture but not as moisture-retentive as black soil.
