What do farmers generally add to improve acidic soil?

Answer and explanation

Correct answer: Slaked lime (calcium hydroxide)

Acidic soil has a pH below the desirable range for many crops. Slaked lime, calcium hydroxide, is a base that reacts with and neutralises excess acids in the soil, thereby raising its pH; option A is correct. Vinegar and lemon juice contain acids and would increase acidity. Common salt is not normally added as a neutralising agent and may harm soil quality in excess.
