Which substance is used to raise pH levels in soil?

• A. Lime or dolomite
• B. Sulfur
• C. Urea
• D. Potassium

Answer: (A)

Lime or dolomite is used to raise pH levels in soil because they are rich in calcium carbonate and magnesium carbonate, compounds that neutralize acidity in the soil. When applied, these substances react with soil acidity, leading to an increase in soil pH, which can promote healthier plant growth by enhancing nutrient availability. Maintaining an appropriate pH level is crucial for optimal plant development, as many nutrients become less accessible to plants in overly acidic conditions. This makes lime or dolomite an essential amendment for soils that are too acidic, thereby supporting a more favorable growing environment for various crops and ornamental plants.
