Answer:
Calcium should be turned into calcium oxide to neutralise the soil.
He can determine by taking a sample of soil in a solution and then can check the nature by diping a Ph scale. If the colour of the solution becomes pale green,then he is sucess.And if the colour of the solution becomes red , then he is not success.
