Which term would you use to describe materials added to soil to improve drainage?

• A. Soil Amendments
• B. pH
• C. Symptom
• D. Surfactant

Answer: (A)

Materials added to soil to improve drainage are called soil amendments. They are used to change the soil’s physical properties—like texture, structure, and porosity—so water can move through more freely. In turf settings, common amendments include organic matter or compost to loosen heavy soils, sand to improve drainage in clay soils, and other conditioners that enhance pore space and aeration. The other options don’t fit this general idea: pH is a measure of acidity or alkalinity, not a material added to soil; a symptom is a sign of a problem rather than a material you add; and a surfactant is a specific type of additive that helps water spread in the soil, but it describes one kind of product rather than the broad category of materials used to improve drainage.
