Question

'X' is an organic substance obtained from the decomposition of plant or animals wastes which provides lots of humus to the soil. Identify the incorrect statements regarding decomposition.

• A. It makes the soil porous
• B. It reduces the water holding capacity of the soil
• C. it increase the number of friendly microbes
• D. It improves the texture of the soil

Answer 1

The correct option is D It improves the texture of the soil

Humus is the dark, organic material formed in the soil when plant and animal matter decays.
It is important as it retains-
1) Moisture content in the soil.

2) Loosens the soil which allows better aeration and drainage.

3) It encourages the increase of soil organisms which help make nutrients available to plants.

4) It makes the soil more porous.

5) High humus content increases water holding capacity of the soil.

So, the correct answer is 'It improves the texture of the soil'.
