Explanation:

1) Humus, the fraction of the soil medium that helps to make minerals available to plant rootlets, is produced in the soil by the decay of animal and plant matter. When soil humus levels are higher, it takes fewer nutrients to produce crops.

2) Humus serves as a source of nitrogen, pho- sporus, and sulfur for higher plants; improves structure, drainage, and aera- tion; increases water-holding, buffering, and exchange capacity; enhances the dissolution of silicate minerals; and serves as a source of energy for the growth and development of micro- organisms.

3) Humus is defined as black organic matter formed in soil due to the decay of dead plant and animal matter. It is organic because of accumulation of carbon and is hence dark in colour. It has very important constituents to keep soil healthy.
