Question

Arrange Land capability classes from "Fit for cultivation" to "not suitable for cultivation":
(A) Light green
(B) Dark green
(C) Yellow
(D) Blue
(E) Red
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D), (E).
• B. (A), (C), (E), (D), (B).
• C. (B), (A), (D), (C), (E).
• D. (B), (A), (C), (E), (D).

Hint:

Remember the core color sequence of the arable classes (Class I to III):
Dark Green (I) \(\rightarrow\) Light Green (II) \(\rightarrow\) Yellow (III).
This sequence (B) \(\rightarrow\) (A) \(\rightarrow\) (C) is present only in Option 4, allowing you to identify the correct answer instantly.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The Land Capability Classification (LCC) is a systematic method of grouping soils based on their capability to produce common cultivated crops and pasture plants without deterioration.
The USDA system groups land into eight classes (I to VIII).
Classes I to IV are suitable (arable) for cultivation with increasing limitations, while Classes V to VIII are not suitable (non-arable) for cultivation.
Specific colors are assigned to each class on land capability maps.

Step 2: Detailed Explanation:
Let us list the standard color codes assigned to the eight Land Capability Classes:
- Class I: Very good land with few limitations. Code color: Dark green (B).
- Class II: Good land with moderate limitations. Code color: Light green (A).
- Class III: Moderately good land with severe limitations. Code color: Yellow (C).
- Class IV: Fairly good land suitable for occasional cultivation. Code color: Pink or Light Red.
- Class V: Not suitable for cultivation due to wetness or stoniness. Code color: Dark Green or Red (E).
- Class VI: Suitable for grazing and forestry. Code color: Orange.
- Class VII: Highly steep land suitable for forestry. Code color: Brown or Red (E).
- Class VIII: Extremely steep, rocky, or swampy land suitable only for wildlife or recreation. Code color: Purple or Blue (D).
According to standard Indian soil conservation mapping guidelines:
- Class I: Dark green (B)
- Class II: Light green (A)
- Class III: Yellow (C)
- Class IV: Pink Red (E)
- Class V to VIII: Blue (D) is often used to denote non-arable classes with extreme limitations or water bodies.
Arranging these colors from "Fit for cultivation" (Class I) to "Not suitable for cultivation" (higher classes):
\[ \text{Dark green (B)} \rightarrow \text{Light green (A)} \rightarrow \text{Yellow (C)} \rightarrow \text{Red (E)} \rightarrow \text{Blue (D)} \]
This gives the sequence: (B), (A), (C), (E), (D).

Step 3: Final Answer:
The correct option is (D).
