प्रश्न
The soil in a field in highly acidic. Name two materials which can be added to this soil to reduce its acidity. Give the reason for your choice.
उत्तर
The soil can be treated with bases such as quick lime (calcium oxide) or slaked lime (calcium hydroxide) to reduce its acidity.
These bases react with the excess acid present in the soil and neutralise its acidity. This increases the pH of the soil, which makes it suitable for the growth of various crops.
