Manures and fertilisers are used in fields to increase the crop yield and make the land fertile.

Manures are made naturally by dead and decaying plant or animal mater .
Manures have high humus content but low nitrogenous content.

Fertilisers are made in factories by processing mainly natural gas.
Fertilisers have adequate amount of nitrogenous and phosphoric content but are low in humus content.

FARMERS GENERALLY MIX MANURES AND FERTILISERS TO GET BETTER YIELD.
