Question:
Humification results in the formation of substance called humus.
Humification results in the formation of substance called humus.
Show Hint
Humification is a vital process in soil fertility, enriching the soil with humus, which aids in water retention and nutrient cycling.

The Correct Option is A
Solution and Explanation
Step 1: Humification is the process by which organic matter, such as plant and animal material, is decomposed by microorganisms into humus. Humus is a dark, nutrient-rich material that contributes to soil fertility. It is typically amorphous (lacking a defined shape or structure), and its composition is complex, consisting of various organic compounds.
Step 2: During humification, microorganisms break down dead plant and animal matter into simpler organic molecules. Over time, these molecules combine to form humus, which helps retain water and nutrients in the soil, promoting plant growth.
Step 3: The other options are not correct:
- (B) Crystalline: Humus is not crystalline, as it is amorphous.
- (C) Liquid: Humus is solid, not liquid.
- (D) Gas: Humus is a solid, not a gas.
Conclusion: Humus is an amorphous substance formed through humification.
