Q.the graph shows how ph of the soil in a farmers field changed over a period of time. at which point A,B,C or D did the farmer apply lime to the field?

 

[tahatehseen]

definitely B as lime is always added to acidic soil to neutralize it! Over here the soil is below pH 7 just before B... At B the farmer added the lime to neutralize the soil
