Question

Give one function which is not performed by the humus.

Answer 1

Humus:

1. Humus is a complex organic substance that results from the breakdown of plant material after underdrawing a biodegradable process of humidification.
2. This process of humidification can occur naturally in soil or during the production of compost.
3. It plays a very important role for maintaining the fertility of soil.

Role and function:

1. Humus contains quite a lot of useful nutrients for the healthy soil.
2. One of the most important nutrient is nitrogen.
3. It has a high water holding ability and maintains the moisture content of the soil.
4. There are various bacteria required for the growth of the plant and humus helps in maintaining those useful bacteria.
5. It binds the tiny soil particles together and improves the soil structure overall.

One function which is not performed by the humus is it does not kill the harmful bacteria present in the soil.
