Assertion: Humus undergoes degradation at very slow rate.
Reason: Humus is highly resistant to microbial action.
Text Solution
Verified by ExpertsThe correct answer is:
A
Humus is a dark, amorphous substance that decomposes extremely slowly because its complex chemical structure is highly resistant to microbial attack.
Due to this resistance, it serves as a long-term reservoir of nutrients that are released gradually into the soil over time.
The physical and chemical properties of humus ensure it remains in the soil much longer than fresh organic matter.
