How can organic matter help improve basic soil?
Answer and explanation
Correct answer: It can form acidic substances on decay
The governing concept is neutralisation or reduction of excess alkalinity in soil. During decomposition, organic matter can produce acidic substances and organic acids. These react with some basic components of alkaline soil and help lower its excessive basicity, improving soil conditions. Organic matter does not turn soil into metal, stop gas movement, or generally make an already basic soil more alkaline. Therefore, the scientifically appropriate answer is option A.
