A farmer's soil is too acidic. What is the most suitable way to improve it for crops?
Answer and explanation
Correct answer: Add slaked lime
Very acidic soil can harm roots and reduce the availability of some nutrients. Slaked lime, Ca(OH)₂, is a basic substance that reacts with excess acidic components and raises the soil pH toward a more suitable range. This is an agricultural application of neutralisation, so option A is correct. Adding more acid would worsen the condition, while salt and sugar do not provide the required neutralising action.
