Which statement best describes the role of fertilizer?

• A. To increase soil fertility by supplying essential nutrients
• B. To kill pests
• C. To control weeds
• D. To improve drought tolerance only

Answer: (A)

Fertilizer’s purpose is to supply essential nutrients to the soil so plants have the building blocks they need to grow and stay healthy. Plants rely on a mix of macronutrients (like nitrogen, phosphorus, and potassium) in larger amounts and micronutrients (such as zinc, iron, and manganese) in smaller amounts. When these nutrients are available in the soil, plants can carry out photosynthesis, develop strong roots, and produce foliage, flowers, and fruit more effectively. Fertilizers are not pesticides or weed killers, so they don’t kill pests or control weeds; their primary job is providing nutrients. They also aren’t used solely to improve drought tolerance, though good nutrition can help a plant cope with stress. The key idea is that fertilizer boosts soil fertility by delivering essential nutrients for plant growth.
