What can generally be added to improve acidic soil?
Answer and explanation
Correct answer: Slaked lime
Acidic soil has a pH below the desirable range for many crops. Slaked lime, calcium hydroxide, is a basic substance that reacts with excess soil acidity and raises the pH toward a more suitable level. Thus option A is correct. Vinegar, lemon juice, and dilute acid are acidic materials, so adding them would generally increase rather than correct soil acidity.
