Question

Given below are two statements:
Statement (I): In vegetable crops, luxury consumption of potassium is a very common feature.
Statement (II): Potassium is more mobile than nitrogen fertilizers.
In light of the above statements, choose the most appropriate answer from the options given below.

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

Hint:

Luxury Consumption: Plants taking up more nutrients than needed for yield, common for Potassium (K). (Statement I is True)
Nutrient Mobility in Soil: Nitrate (a form of N) is very mobile and leaches easily. Potassium (K\(^+\)) is moderately mobile, less prone to leaching than nitrate. Ammonium (another N form) is less mobile initially. The relative mobility can be complex and context-dependent.

Answer 1

The Correct Option is A

Step 1: Vegetable crops commonly absorb potassium beyond their yield-related needs, this is luxury consumption, so Statement (I) is true.
Step 2: Potassium moves through the soil root zone relatively freely, while nitrogen fertilizers are more prone to rapid loss through leaching or volatilization.
Step 3: This makes Statement (II) true as well.
Step 4: The correct answer is both Statement (I) and Statement (II) are true.
