Plant nutrients are classified as macronutrients or micronutrients based on the quantity required by the plant. Macronutrients are needed in relatively large amounts, while micronutrients are needed in very small amounts. The primary macronutrients are Nitrogen (N), Phosphorus (P), and Potassium (K).
