Question

The concentration of macronutrients in dry plant tissues is

• A. Less than 0.1 percent
• B. More than 0.1 percent
• C. Less than 0.01 percent
• D. More than 0.01 percent

Hint:

Nutrient concentrations:
- Macronutrients: > 0.1% (N, P, K, Ca, Mg, S).
- Micronutrients: < 0.1% (Zn, Mn, Fe, Cu, B, Mo, Cl, Ni).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of the concentration of macronutrients in plant tissues.

Step 2: Detailed Explanation:
Macronutrients are required in large quantities and are present in plant tissues at concentrations > 0.1% (1000 ppm).
Micronutrients are present at concentrations < 0.1%.
Thus, the concentration of macronutrients in dry plant tissues is more than 0.1%.

Step 3: Final Answer:
Thus, the concentration of macronutrients is more than 0.1%, which corresponds to option (B).
