If soil is too basic, which method can help improve it?

Answer and explanation

Correct answer: Adding organic matter

The governing concept is neutralisation and soil pH management. Highly basic soil has a pH above 7, so adding more alkaline substances such as lime or sodium hydroxide would make the problem worse. Organic matter, such as compost or manure, decomposes gradually and can produce mildly acidic substances that help reduce excessive alkalinity and improve soil structure. Therefore, option B is correct; soap is not a suitable soil amendment.
