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

$\bf\huge\underline\red{Answer}$

Slaked lime, quicklime and chalk are all basic in nature. Thus, if the soil is acidic, the farmer will add these basic substances so that the pH of soil becomes neutral (pH = 7). This value of pH is very essential for healthy growth of plants.

If the soil is acidic in nature (PH below 7) then such field should be treated with quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate).
