Question

Essential elements like Nitrogen, Phosphorus, Potassium are supplied to plants growing in soil through:

• A. Irrigation
• B. Root exudates
• C. Fertilizers
• D. Atmospheric deposition

Hint:

Using balanced fertilizers can prevent nutrient imbalances and promote healthier plant growth by supplying all essential nutrients in appropriate proportions.

Answer 1

The Correct Option is C

Step 1: Understanding nutrient sources.
While irrigation and atmospheric deposition can provide some nutrients, they primarily supply water and trace elements. Root exudates mainly involve organic compounds affecting nutrient availability but not supplying the major elements directly. 
Step 2: Role of fertilizers.
Fertilizers are specifically formulated to provide plants with essential nutrients such as Nitrogen (N), Phosphorus (P), and Potassium (K). These macronutrients are vital for various physiological activities in plants including growth, root development, and photosynthesis.
