Question

Which of the following is not a characteristic of humus?

• A. It is rich in organic matter such as lignin and cellulose
• B. It is colloidal in nature and serves as a reservoir of nutrients
• C. It is further degraded by the process of humification
• D. None of the above

Answer 1

The correct option is C It is further degraded by the process of humification

Humus is a dead, gummy substance which is rich in lignin and cellulose. Its synthesis process from raw organic remains, is known as humification. This organic humus which is formed by plant and animal matter decomposition can be further degraded by microbial activity. It is colloidal in nature and serves as a reservoir of nutrients. So, the correct option is "d" which is not a characteristic of humus.
