Question

Given below are two statements:
Statement (I): Soil profile is a vertical section of the soil from the surface through all its horizons.
Statement (II): Soil texture is the arrangement of individual soil particles with respect to each other into a pattern.

In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Keep this distinct in mind:
- Texture: % Sand, Silt, and Clay (cannot be changed easily).
- Structure: Arrangement/Pattern of particles (can be altered by tillage).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Soil profile and soil texture are fundamental parameters in soil science used to characterize soil layers and soil physical composition.

Step 3: Detailed Explanation:
1.

Statement (I): A soil profile is defined as a vertical cross-section of the soil extending from the surface downward to the parent rock. This exposure displays various distinct horizontal layers, known as soil horizons (O, A, E, B, C, R). Thus, Statement (I) is correct.
2.

Statement (II): Soil texture refers to the relative proportions of sand, silt, and clay separates in a soil mass.
The physical arrangement of these individual soil particles into aggregate patterns or clusters (e.g., platy, blocky, granular) is termed

soil structure.
Therefore, Statement (II) incorrectly defines texture, making it incorrect.

Step 4: Final Answer:
The correct option is 3, which corresponds to Statement (I) is correct but Statement (II) is incorrect.
