Question

Why is Black soil highly moisture retentive?

Options

• It has fifty percent of clay content

• It is formed of weathered lava rocks

• It has high quantities of lime and iron

• All of the above

Answer 1

It has fifty percent of clay content

Explanation:

Black soil is highly moisture-retentive because of its high clay content, about 50%. This clay allows the soil to retain water for long periods, making it particularly suitable for crops like cotton that require constant moisture. While black soil is formed from weathered lava rocks and contains lime and iron, the primary reason for its moisture retention is its clay composition.
