A complete fertilizer contains which nutrients?

A complete fertilizer contains which nutrients?

• A. Nitrogen, Phosphorus, and Potassium
• B. Nitrogen only
• C. Potassium only
• D. Nitrogen and Sulfur

Answer: (A)

A complete fertilizer provides the three primary macronutrients plants need in larger amounts: nitrogen, phosphorus, and potassium (N-P-K). Nitrogen drives leafy growth and turf color, phosphorus supports root development and energy transfer, and potassium boosts overall vigor and stress tolerance. Because a complete fertilizer supplies all three, it supports balanced growth in a single product. Choices that include only one nutrient or omit one of the essential macronutrients are incomplete. While some products may also contain sulfur or micronutrients, the term complete here refers to including N, P, and K together.
