Question

Which of the following should be added to acidic soil to make it neutral?

• A. Vinegar
• B. Slaked lime
• C. Organic compost
• D. Water

Answer 1

The correct option is B Slaked lime

Acidic soil does not support the plant growth thus, it need to be neutralised by adding a base to it.
Out of the given options, vinegar and organic compost are acidic in nature, water is neutral and slaked lime i.e. calcium hydroxide is basic in nature.
So, in order to neutralise the acidic soil, slaked lime should be added to it.
