Manures and
fertilisers
Manures
Manures are
decomposed organic matter derived from plants and animals. Besides providing
supplement of plant nutrients, manures are beneficial in many ways. They
enhance biological activities in the soil, and also improve structure, colour,
aeration and water-holding capacity of the soil. Manures are slow in
decomposing, hence, they release plant nutrients gradually, which can be used
as organic fertilisers in agriculture.
Classification
of organic manures
Manures can be
classified in three groups as manures of plant origin, animal origin and
composite derived from both plants and animals.
1. Manures of
plant origin
Oil
cake: The solid platy residue left after the extraction of oil from seeds is
known as ‘oil cake’. These oil cakes are applied to add nutrients to the soil,
as well as, to improve the soil structure. The cake formed during the
extraction
of oil from seeds may be:
edible oil cakes: Groundnut cake, linseed cake, rapeseed
cake, sesamum cake, etc.
non-edible oil cakes: Karanj cake, neem cake, castor
cake, etc.
Plant
residues: Straw, husks, stalks, saw dust and wood ash also add nutrients to the
soil.
Green
manures: Green manure crop is raised and turned into the soil for
decomposition. Green manures improve the physical structure of the soil, as
well as, soil fertility. Crops, like dhaincha and sunn hemp are used as
green manure.
2. Manures of
animal origin
This includes
animal’s settled sludge, (dry) dried blood, night soil and sludge manure, fish
manure bonemeal, cattle dung and urine mixed, sheep dung and urine mixed, pig
manure, poultry manure, etc.
