Vermi composting

1. Introduction :
 Vermis = worm, culture = growth
 Composting done with the help of earthworms is known as a
vermicompost.
 The habitat, habits, nutrition, reproduction of different
earthworms differ, hence the need to select the proper species for
the given need.
 At khanapur village their is a no provision of disposal of
biodegradable waste so we adopt the technique of disposal of
biodegradable waste through vermi-composting.

2. Solid Waste Distribution At khanapur village
Biodegradable
waste
60%
Non-
Biodegradable
waste
30%
other waste
4%
Recyclables
6%

3. Scope:
• The khanapur village has not adopted appropriate waste
disposal method.so vermicomposting is the best practice to
decompose the biodegradable waste in that village.
• Organic manure will obtained as well as soil fertility is also
be enhanced .
• Vermiwash is also to be used for enhancing soil grading .

4. Needs For Vermicomposting:
 It improves soil structure
 Easy to handle, apply and store do not hold any bad
smell it can be used as a soil conditioner or amendment.
 Encourage the population of useful soil microbes in the
soil.
 Increases the natural decomposition ability in the soil.

5. Purpose :
• To improve the waste decomposition methods
like vermicomposting
• To promote organic farming through
vermicomposting organic manure
• To enhance soil fertility
• To keep village healthy and wealthy

6. What is vermi-composting ?
 Vermicompost (vermi-compost) is the product of
the decomposition process using various species
of worms, usually red wigglers, white worms,
and other earthworms, to create a mixture of
decomposing vegetable or food waste, bedding
materials, and vermicast. This process is called
vermicomposting.

7. Types of worm :
 Eisenia foetida (red earthworm),
 Eudrilus eugeniae (night crawler), perionyx
excavatus etc.

8. Red worm :
 Red earthworm is preferred because of its high multiplication rate
and thereby converts the organic matter into vermicompost within
45-50 days.
 Since it is a surface feeder it converts organic materials into
vermicompost from top.

9. Characters Eisenia Foetida
 Body length
 Body weight
 Maturity
 Conversion rate
 Co coon production
 Incubtion of co coon
 3-10cm
 0.4-0.6g
 50-55days
 2.0q/1500worms/2mont
hs
 1 in every 3 days
 20-23 days
CHARACTERISTICS OF RED WORM :

10. Initial steps :
 Appropriate site selection
 Vermiculture site preparation
 The biodegradable waste

11. • Organic waste like crop residues, kitchen
wastes, market wastes, bio-wastes of agro
based industries, livestock wastes, weeds and
• other biodegradable wastes.
Substrate for vermi-composting :

12. Cowdung:
 Cowdung is considered as additive for initial feeding of earth
decomposed cowdung is ideal for vermicomposting.
 Chemical fertilizers should not be added in vermicomposting
beds. The vermi beds should be protected from insecticidal
sprays,
 The worms should be protected from ants, frogs, rats and birds.
 Moisture level of the beds should be monitored regularly (40-
50% moisture) and water should be sprayed on the beds as and
when required.
 Do not allow any stagnation of water in the bed by providing
suitable drainage.

13. Products of vermiculture :
 Vermicompost
 Vermi wash

14. Vermicompost :
 The final product of vermicomposting is black granular crumbly
organic manure, which contains plant nutrients like Organic
Carbon (9.15 to 17.98%), total Nitrogen (1.5 to 2.1%), total
Phosphorus (1.0 to 1.5%), total Potassium (0.6%), available
Sulphur (128 to 548 ppm). Calcium and Magnesium 22 to 70
me/100g,.
 has a positive effect on vegetative growth, stimulating shoot and
root development.
 It contains some antibiotics and actinomycetes that help in
increasing resistance of crop plants against pest and diseases.
 Vermicompost also has very high porosity, aeration, drainage and
water holding capacity which will be helpful for maintenance of
soil health.

15. Vermiwash :
 Vermiwash is a liquid that is collected after the passage of
water through a column of worm action and is very useful as
a foliar spray. It is a collection of excretory products and
mucus secretion of earthworms along with micronutrients
from the soil organic molecules.

16. Vermiculture bed preparation :
i. Make a basic bed of size 24 cft (L-8ft,B=3ft, Ht=1ft) with one brick (9
inch x 4 inch x 3 inch) size containment all round the bed
ii. .Alternatively, brick tanks of same dimensions having 2 feet height may
be constructed
iii. Apply a layer of cow dung slurry on the base
iv. Put one inch sand on the cow dung slurry plastered bed
v. Followed by putting 2 inch thick organic waste
vi. Put 9 inch thick feeding material

17. Process :
Transfer
Apply earth worm
Cover the bed
Sprinkle water
Scrapping
Screen

18. Conclusion :
• The vermicomposting method for disposal of
biodegradable waste is best suited for the khanapur
village
• Vermicomposting method not only improve the
manure quality but also improve the soil fertility
• Increases the nitrogen , potassium ,phosphorus in
natural way in the soil without any chemical
additives inserting in it .
• Keep soil nutrients and soil texture healthy
