Humification reuslts in the formation of

Options

A. colloidal, basic substance
B. acidic, dark coloured substance
C. amorphous, light coloured substance
D. light coloured, colloidal substance

Answer

**Step-by-Step Solution:**

1. **Understanding Humification**: Humification is a process that occurs during the decomposition of organic matter in the soil. It involves the transformation of decomposed organic materials into a stable form known as humus.

2. **Decomposition Stages**: The decomposition process consists of several stages:
- **Fragmentation**: Large organic particles are broken down into smaller pieces.
- **Leaching**: Water-soluble substances are washed away, and some nutrients may be lost to deeper soil layers.
- **Catabolism**: Microorganisms, such as bacteria and fungi, further break down the organic material into simpler compounds.

3. **Formation of Humus**: After these stages, the remaining organic matter undergoes humification, which results in the formation of humus. Humus is characterized by its dark color and colloidal nature.

4. **Identifying the Correct Option**: The question asks what humification results in the formation of. The options provided are:
- A) Colloidal basic substance
- B) Acidic dark colored substance
- C) Amorphous light colored substance
- D) Light colored colloidal substance

5. **Analyzing the Options**:
- Option A is incorrect because humus is not a basic substance.
- Option B is correct as humus is indeed an acidic, dark-colored substance.
- Option C is incorrect because humus is not light-colored.
- Option D is also incorrect for the same reason as C.

6. **Conclusion**: Based on the analysis, the correct answer is **B) Acidic dark colored substance**.
