Accepted Answer

The advantages of using chemical fertilizers are:

They are rich in plant nutrients like nitrogen, phosphorus, potassium etc.

They are nutrient specific and are utilised for the specific needs of the plant.

They are easily soluble in water and can be readily absorbed by the plant.

The disadvantages of using chemical fertilizers are:

Excessive use of them changes the chemical nature of the soil and makes it less fertile. For example, overuse use of fertilizers can make the soil highly acidic or alkaline.

Results in the ‘burning’ (browning) of the leaves of the crop plants and affects the quality of crops as well as human health.

The excess use of chemical fertilizers causes water pollution and may also leach into the soil with rainwater to poison the groundwater.

They kill many organisms living in the soil and also causes air pollution.
