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?
The farmer has to first make sure whether the soil is acidic or basic. For this he has to take the sample of his soil to laboratory and get it tested.
If the soil is Acidic, we will have to add some basic substance like Dry lime, or limestones so that they neutralize the excess acid of the soil.
If the soil is Basic, we will have to add acidic substances to neutralize its effects. Generally organic substances are added in the soil in this case because they generate acids on decomposition.
