Question

what is hummus how it is formed​

Answer 1

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. This material is called leaf litter. When animals die, their remains add to the litter.Humus is partially decayed organic matter. It makes the soil porous, thereby, increasing its air and water holding capacity. It is rich in nutrients that promote plant growth. Being black, it absorbs heat to warm up the soil.
