Under what soil conditions do you think a farmer would treat the soil of his fields with quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate).

If the soil is acidic and unsuitable for agriculture, the farmer can treat it with quick lime, slaked lime, or chalk to neutralize the acidity.

• Quicklime, slaked lime and chalk are basic in nature. Farmers usually use quick lime slaked lime or chalk in order to increase the fertility and also when the soil becomes too acidic due to many reasons they use these bases.
• These bases work as a neutralizing agent which neutralizes the acid content in the soil. Here the reaction will be a neutralization reaction.
