Which of the following options are wrong regarding humus.

• A. Humus stabilizes the texture of the soil.
• B. Humus reduces the soil fertility.
• C. Humus enhances the soil fertility.
• D. Humus promotes air and water circulation in soil.

Answer 1

The correct option is B

Humus reduces the soil fertility.

The rotting dead matter in the soil is called humus. It is mainly found in A-Horizon of the soil. The humus, as it is composed of organic matter (dead matter), makes the soil fertile and provides nutrients to growing plants. So humus is very important as it makes the soil fertile. It is also home to many organisms. This layer is generally soft, porous and can retain more water.
