What is a common practice to raise soil pH when it is too acidic?

• A. Adding compost
• B. Applying lime
• C. Adding sand
• D. Using fertilizer

Answer: (B)

Applying lime is a common practice used to raise soil pH when it is too acidic. Lime, which can be derived from limestone, contains calcium carbonate or magnesium carbonate, and it works by reacting with the acids in the soil. This reaction neutralizes the acidity, resulting in a higher pH level, which is important for creating a more favorable environment for plant growth, including grass in golf courses. The other options, while useful in different contexts, do not effectively raise soil pH. Compost might improve soil structure and increase nutrient content but has a negligible effect on soil acidity. Adding sand primarily alters soil texture and drainage but does not influence pH levels. Fertilizers can affect overall soil health and nutrient availability but are not used specifically to adjust pH in acidic soils.
