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