    What do you mean by soil treatment?

    Answer:

    When a farmer uses excessive chemical fertilisers in the soil then the soil becomes acidic. Plants do not grow well when the soil is either too acidic or too basic. When soil is too acidic, it is treated with bases. If the soil is too basic, organic manure is added to it. Organic manure releases acids which neutralise the basic nature of the soil.
