Step 1: Understanding the Concept:
The USDA Land Capability Classification system categorizes land into eight classes (I to VIII) based on their limitations for agricultural cultivation and erosion hazards.
Step 3: Detailed Explanation:
Let us analyze the traits of Class II land:
1.
Class II lands have moderate limitations that restrict the choice of crops or require simple, moderate conservation practices (such as contour tillage, strip cropping). Thus, (A) is correct.
2. These lands are characterized by gentle slopes. Thus, (B) is correct.
3. They may suffer from minor limitations like slight to moderate salinity. Thus, (D) is correct, and (C) (severe salinity) is incorrect.
4. Class II lands are highly fertile and suitable for regular cultivation; they are not restricted to permanent forest (E) (which is characteristic of highly restricted Class VII or VIII lands).
Therefore, only (A), (B), and (D) are correct.
Step 4: Final Answer:
The correct option is 1, which corresponds to (A), (B) and (D) only.
