Which term refers to a chemical or natural substance added to soil to increase its fertility?

• A. Fertilizer
• B. Pesticide
• C. Monocropping
• D. Tropical climate

Answer: (A)

Adding nutrients to soil to boost plant growth is what a fertilizer does. A fertilizer is a chemical or natural substance applied to soil to increase its fertility by supplying essential nutrients that crops need. These nutrients often include nitrogen, phosphorus, and potassium, and can come from synthetic blends or organic sources like compost or manure. By replenishing nutrients removed by harvesting and supporting better growth, fertilizers help raise crop yields. Pesticides target pests, monocropping is a farming practice of growing the same crop repeatedly, and a tropical climate describes weather conditions—not a soil amendment.
