Question

Humus present in the soil determines the fertility of the soil.

• A. True
• B. False

Answer 1

The correct option is A True

The rotting dead matter in the soil is called humus. The uppermost horizon of soil is generally dark in colour as it is rich in humus and minerals. The humus makes the soil fertile and provides nutrients to growing plants. This layer is generally soft, porous and can retain more water. It is called the topsoil or the A-horizon.
