Humus is a natural material ​

Answer 1

HEYAA BUDDY...

Answer:

Humus is dark, organic material that forms in soil when plant and animal matter decays. When plants drop leaves, twigs, and other material to the ground, it piles up. ... Earthworms often help mix humus with minerals in the soil. Humus contains many useful nutrients for healthy soil.

Answer 2

Answer:

Humus is a natural material because its formation is a natural process. It is the dark-coloured layer of top soil that is rich in nutrients. The decomposers convert the dead plants and animals into humus that is utilised by the plants. It increases the fertility of the soil.
