Which statement best describes a soil amendment?

• A. A material added to improve soil properties or fertility
• B. A pesticide used to protect crops
• C. A plant disease
• D. A tool for measuring soil moisture

Answer: (A)

A soil amendment is a material added to soil to improve its properties or fertility. It’s used to address issues like poor texture, low organic matter, incorrect pH, or drainage, and can be organic (like compost) or inorganic (like lime or gypsum). By changing the soil’s structure, moisture-holding capacity, and nutrient availability, amendments help plant roots grow more effectively and access nutrients. This is different from a pesticide (which protects crops from pests), a plant disease (a pathogen), or a tool for measuring soil moisture (an instrument).
