Which of the following statements about lime and soil pH is true?

Explanation:
Lime raises soil pH by neutralizing soil acidity. Soil pH reflects how acidic or basic the soil solution is, and many soils become acidic from rainfall, crop nutrient uptake, and organic matter breakdown. Lime, often calcium carbonate, is alkaline and dissolves in soil water to release calcium ions and carbonate. The carbonate neutralizes hydrogen ions in the soil solution (and can also reduce exchangeable aluminum toxicity), effectively lowering the acidity and increasing pH. In short, adding lime makes the soil less acidic, which is why it’s used to raise pH.
