Question

Explain explain how fertilizers are different from manure

Answer 1

Manure is a natural substance prepared by the decomposition of animal excreta and plant wastes. They can be organic or inorganic in nature. Manure provides humus to the soil and increases soil fertility.

A Fertiliser is any material of natural or synthetic origin that is applied to soils or to plant tissues to supply one or more plant nutrients essential to the growth of plants.

Answer 2

Difference between fertilizers and manures-

Manure-

$\implies$ Manure is a natural substance obtained by the decomposition of cattle dung and plant residues.

$\implies$ Manure can be prepared in the field.

$\implies$ Manure provides a lot humus to the soil.

$\implies$ Manure is relatively less rich in plant nutrients.

Fertilizers-

$\implies$ Fertilizer is a man- made inorganic salt.

$\implies$ Fertiliser is prepared in factories.

$\implies$ Fertilizer doesn't provide any humus to the soil.

$\implies$ Fertilizers are very rich in plant nutrients like nitrogen, phosphorus and potassium.
