Answer:
Soil Treatment
Excessive use of chemical fertilisers makes the soil acidic. Plants do not grow well when the soil is either too acidic or too basic. When the soil is too acidic, it is treated with bases like quick lime (calcium oxide ) or slaked lime calcium hydroxide . If the soil is basic, organic matter is added to it. Organic matter releases acids which neutralises the basic nature of the soil.
Factory Wastes
The wastes of many factories contain acids. If they are allowed to flow in to the water bodies, the acids will kill fish and other organisms. The factory wastes are, there fore, neutralised by adding basic substances.
