The following fertilizers can be used to neutralize soil acidity except
Answer Details
Ammonium nitrate cannot be used to neutralize soil acidity. This is because ammonium nitrate is an acidifying fertilizer, meaning that it lowers the pH of the soil when applied. The other options, wood ash, limestone, and calcium phosphosilicate, are all alkaline materials that can be used to neutralize soil acidity. Wood ash is a quick-acting source of potassium and calcium that also raises soil pH. Limestone and calcium phosphosilicate are both slow-acting sources of calcium that gradually raise soil pH over time.
