Question

Explain how fertilisers are different from manure.

Solution

Differences between fertilisers and manure:

Fertiliser Manure
Fertilisers are commercially available plant nutrients Manure is a natural substance prepared by the decomposition of animal excreta and plant wastes
They can be organic or inorganic in nature. Manure is known to have a large quantity of organic materials and very little amount of plant nutrients.
They ensure healthy growth and development of plants by providing them with nitrogen, phosphorus, potassium, etc They help in enriching the soil with organic matter and nutrients.
The addition of fertilisers to the soil requires special guidelines such as dose time, post addition precautions, etc., to be followed. The addition of manure does not require any special guidelines.
A fertiliser does not provide any humus to the soil. Manure provides humus to the soil and increases soil fertility.
Its excessive use causes water pollution. It cannot replenish organic matter of soil. It protects the environment and helps in recycling farm waste.
