Why is earthworm considered a farmer’s friend? Explain humification and mineralisation occurring in a decomposition cycle. |
|
Answer» Earthworms help in breakdown of complex organic matter as well as loosening of the soil. This helps in the proper growth of the crops. Therefore, they are considered farmer’s friend. • Humification: The process of accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate is called humification. • Mineralisation: The process by which humus is further degraded by some microbes to release inorganic nutrients is called mineralisation. |
