Which substance is added to improve excessively acidic soil?
Answer and explanation
Correct answer: Lime
Excessively acidic soil can prevent plants from absorbing nutrients properly and may reduce crop growth. Lime, commonly containing calcium oxide, calcium hydroxide, or calcium carbonate, is basic and is added in a suitable quantity to neutralise some of the excess acidity. Therefore option A is correct. Vinegar and lemon juice are acidic, while sulfuric acid would increase acidity and damage the soil further rather than improve it.
