Q. Consider the following statements:
1.Humification leads to accumulation of a dark colored amorphous substance called humus.
2.The humus is degraded by some microbes and the release of inorganic nutrients occurs by the process known as mineralization.
Which of the statements given above is/are correct?
Answer: C
Notes:
Explanation: Humification leads to accumulation of a dark colored amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate.
Being colloidal in nature it serves as a reservoir of nutrients. The humus is further degraded by some microbes and the release of inorganic nutrients occurs by the process known as mineralization.
