Organic Food products now a days has increasing demand as compared with the actual supply. Usually the term used for agricultural products which is grown by ideal farm practices without using any chemical or synthetic fertilizer. Here Organic Manure or compost plays a vital role in Organic Farming.
Manure
has been used for centuries as a fertilizer for farming, as it is rich in
nitrogen and other nutrients which facilitate the growth of plants. Manure is
nitrogen rich organic material which is used to fertilize the land and common
in farming practices across the India. It is consisting of faces and urine of
domestic animals, at times rich with cow dung or animal dung and may be with or
without litter such as straw, hay etc. In India animal husbandry is quite
common along agriculture and hence the preparation of different form of manure with
advantage is known to farmers. Faecal material of Grazing animals constitutes
an enormous fertility sources as a manure while added in soil as the food they
eat constitute nitrogen, phosphorus and potassium.
"Organic Manure usually have a less N-P-K. It works
slowly. On application of Organic Manure, soil use the same in the same amount it
requires for growth. This means that both the soil and the plants in it get the
nutrition they need when they need it"

Chemical
fertilisers are richer in nitrogen as compared with the Organic manure however
has several adverse impacts on soil fertility in log term. Study suggests that
1 ton of Organic manure contains 4.5 Kg of Nitrogen, 2.25 Kg of Phosphorus
pentoxide and approx. 4.5 kg of Potash. Hence organic manure in turns requires
to be added in high volume as compared with chemical fertiliser. Manure is rich
in organic matter or humus, this in turn enhance the soil capacity to absorb
and store more water and can help in reducing erosion.
There
is no specific method that needs to be applied for preparation of manure.
Animal waste as cow dung can directly be mixed with soil as a manure. However,
while producing the organic manure in volume, the animal faces along with the
daily home organic wastes, dry leaves etc can be mixed.

Compost:
Composting
is a process by which organic wastes are converted into organic manures by
means of biological activity under controlled conditions. In other word
composting is defined as a method of solid waste management whereby the organic
component of the solid waste stream is biologically decomposed under controlled
conditions to a state in which it can be handled, stored and applied to the
land without adversely affecting the environment. It is an important technique
for recycling organic agricultural, industrial wastes and for improving the
quality and quantity of organic manure. The objectives in composting are to
stabilize the putrescible organic matter in raw agricultural and industrial
wastes produce a uniform, slow release organic fertilizer which stimulates soil
life, improves soil structure; helps plants to tolerate/ resist pests and
diseases reducing offensive odours, killing weed seeds and pathogenic
organisms.

"Chemical fertilizers are composed of synthesized or
processed chemicals that tend to give a higher nitrogen (N), phosphorus (K) and
potassium (P). While application of the same to soil, tends to absorb more
quickly by plants than Organic Manure "
Understanding Difference between Organic Manure and chemical Fertilizer:
Do
you know what is the difference between Organic Manure and Chemical fertiliser?
Both is helping plants with nitrogen, phosphorus etc. Why Organic Manure is
safe as compare with Chemical fertiliser?
Organic Manure are made from animal faces (ex: cow dung), and natural plant
and animal materials. Chemical or synthetic, fertilizers are made up of organic
ingredients. On application of Organic Manure soil usage, the same in the same
amount it requires for growth. Over application of Manure or compost may or may
not harm the soil or plants. Whereas the chemical fertilizer quickly and simply
feed the plant without enriching the soil and may contribute to a toxic buildup
of salts in the soil when overapplied.
Benefit of Using Manure
or compost:
- Safe for use as it Increases soil carbon and reduced
atmospheric carbon levels
- Useful in reduction of soil erosion and runoff
- It also helps in reducing nitrate leaching
- If used as a primary source of fertilizer, then have long
term positive impact on soil health
- Improve the soil and required organic materials this
helps in storage of water, increase in microbial activity such as mycorrhiza
that helps in nitrogen fixation in soil
- It is safe in handling. Accidental mixing of it with runoff
water or lake has no adverse impact on flora or fauna. Chemical fertilizer requires
specific handling and may impact or pollute if mixes accidently or by
overapplication to any source of water
- Organic Manure or compost may be more expensive than
chemical fertilizer
Government
of India Schemes providing assistance
The
Government is promoting Organic Manure by providing financial assistance under
the following schemes:
- Under Paramparagat
Krishi Vikas Yojana (PKVY)
financial assistance is provided forpromotion of Organic farming through adoption of organic village by
cluster approach and PGS certification.
- Under Mission for Integrated Development of Horticulture financial
assistance is provided for setting up vermicompost units @50% of the cost
subject to a maximum of Rs.30,000/- per beneficiary.
- Under National
Project on Management of Soil Health and Fertility (NPMSHF)
thereis provision for promotion of organic fertilizer up to Rs.500/- per hectare.
- Assistance is also available for Organic
Manure under Rashtriya
Krishi Vikas Yojana (RKVY).
