A farmer was unhappy because of his low crop yield. He discussed the problem with an agricultural scientist and realised that the soil of his field was either too acidic or too basic. What remedy would you suggest the farmer to neutralise the soil?
$$\textbf{Concept:}$$ a chemical reaction in which an acid and a base interact with the formation of a salt; with strong acids and bases the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water.
$$\bullet$$ When the soil of his field is too acidic, it is to be treated with bases like slaked lime(calcium hydroxide) or quicklime(calcium oxide).
The organic matters are added to the soil if the soil of his field is too basic. Organic matter releases acids that neutralize the basic nature of the soil.
