Vermicompost and Vermiculture:

Adding WORM CULTURE

 

“Culturing of earthworms and their application for a variety of purposes is what is meant by Vermi composting by vermi culture”.

a) Selection of species:
The epigeic species have been fouynd to be useful for compost making and the most commonly used species are 'Eisenia foetida' Perionyx excavatus' and ''Eudrillius eugiene'.These sprcies are fast breeders and feed actively on organic matter high in nitrogen!

b) Base materials required:

 

 

Crop residues ,tree leaves and animal dung are the the basic materials required.Agricultural wastes like sugarcane trash,weeds hedge cuttings ,saw dust, coir waste,paddy husk, cattle dung, effluent slurry, from bio-gas plant, excreta of sheep, horse , pig, poultry droppings (in small quantity) and vegetable wastes are ideal food for earth worms. City garbage or even biodegradable organic sludge, a waste product from ETP of any industry can also be used for feeding worms.

 

c) Containers for culturing:

Earth worm culturing should be done under shelter to avoid direct sunlight and heavy downpour . Either brick lined pits , plastic tubs, wooden boxes ,earthen pots or even on surface of soil by making heap of organic matter ,culturing can be done.Size of container should be 1 m x 1 m x 0.3 m .In case of pit or heap method dimensions may be changed to convenience , however ,depth of pit or height of heap should not be more than 45 cms.

 

d) Preparation of bed :

 

Step by step method of preparation of wormiculture bed has to be followed for good results.

First step: Select a container or dig a pit of appropriate dimensions as mentioned above wherever compost is to be prepared.

Second step: Make a bed of 10 cm height using any of the base materials (coir waste, paddy husk, sugar cane trash etc>)collected. Give a layer of soil on it. Sprinkle water on it to get a moisture level of 40-45%.The bed should appear wet.

Third step: Mix the organic waste with cattle dung in equal quantity and pour appropriate quantity of water over it so as to make a homogenous mixture. Effluent slurry from bio-gas plant is best used for this .Keep this mixture for two weeks. During this period heating of substrate will take place. Give turning to the material 2-3 times at 4-5 days interval and transfer it on the layer of bedding prepared earlier.

Adding the Worm culture

 

Fourth step: Introduce cocoons or worms (if culturing is done for the first time , it is advisable to introduce worms) in the bed at the rate of 2000 worms for 400 kgs of feed mix. as prepared in third step. Then the feed mix is to be spread uniformly on the culture bed .Add 5-10 % neem cake in the feed mix. Neem cake in small quantities has beneficial effect on the growth of worms.

Fifth step: Cover the bed with Gunny cloth .Sprinkle water over the cloth periodically to keep gunny cloth wet. The worms feed actively on organic matter and assimilate only 5-10 % and rest isexcreated as loose granular mounds of vermicastings on the surface away from the feed source ,Thus the worms will convert the feed mix into vermicastings in 60 days . The vermin compost once formed completely will give the smell of moist soil.

Sixth step: Take out the vermi compost and make a heap in sunlight on a plastic sheet . Keep for 1-2 hours .The worms will gather at the bottom of heap. Remove vermin compost on top and the worms settled down at the bottom can be carefully collected for use in the next batch of vermi composting.

e)Precautions for compost making : Finished Product -vermicompost

1. Moisture level in the bed should not exceed 40-50%.Water logging in the bed leads to anaerobic condition and change in pH of medium.This hampers normal activities of worms leading to weight loss and decline in worm biomass and population .

2. Temperature of bed should be within the range of 20-30 degree centigrade.

3. Worms should not be injured during handling .

4. Bed should be protected from predators like red ants, white ants, centipedes and others like toads,rats, cats , poultry birds and even dogs.

5. Frequent observation of culture bed is essential as acumaulationd of casts retards growth of worms.

6. Space is the criterion for grow th and estblishment of culture .Minimum space required is 2 square meter per 2000 worms with 30-45 cm thick bed.

7. Earth worms find it difficult to adopt themselves in new environments hence addition of inoculam as a bait from earlier habitat helps in early adaptation to new site of rearing.

 

Best composting tips:

1.Mixture 0f cattle ,sheep, and horse dung with vegetable wastes forms ideal feed for worms.

2.Addition of neem cake in small quantity enhances growth of worms.

3. Biogas slurry aged aerobically for 15 days enhances vermi composting process.

What is vermicomposting?

Vermicomposting is composting with worms. It is typically done indoors in a closed bin populated with red wiggler worms that eat organic waste and expel it as worm castings, or droppings.

What is vermicompost?

Vermicompost is a combination of worm castings and decomposed organic material, as well as worms, worm cocoons, and other decomposer organisms. It is the end product of the vermicomposting process.

top

Why is it called vermicomposting?

Vermi is Latin for worm. Vermicomposting simply means composting with worms.

top

What are worm castings?

Worm castings are the worm's droppings or manure. Worm castings contain decomposed organic material, soil, and bacteria.

top

How does vermicomposting help the environment?

Vermicomposting lets us recycle just like nature does. A vermicompost bin mimics natural processes, allowing organic waste to break down into nutrient-rich compost, which can be returned to the soil to help new things grow. Vermicomposting helps the environment in the following ways:

  • Reduces Waste Sent to our Dump Sites - Up to 30% of our daily household waste is organic.
  • Reduces Greenhouse Gas Emissions - Organics buried in a dump site break down very slowly and without the presence of oxygen. As a result, methane gas (a greenhouse gas) is produced.
  • Reduces Pollution - When organics break down without the presence of oxygen, such as in a dump site, a toxic liquid known as leachate (the liquid that runs from a dump) is produced. Leachate can pollute our soil and water sources.
  • Reduces the Need for Chemical Fertilizers and Pesticides - Finished vermicompost is natural fertilizer that returns valuable nutrients back into the soil, promoting the growth of healthy plants.

I'm squeamish around worms, can I still vermicompost?

Yes. You will need some comfort-level around worms, as you will see and touch some worms when you add food waste and harvest the finished vermicompost. With daily use you will rarely see many worms, as they like to stay below the bedding surface. You may notice that the worms aren't as "gross" as you may have expected them to be and you may start to love worms.

top

Can I have a vermicompost bin in my classroom at school?

Yes. Composting with worms is a great way to show your students how organic waste breaks down naturally. Vermicomposting is fun and interesting for all grade levels. Contact us to request a vermicomposting demonstration for your class or have a look at our Guide to Classroom Vermicomposting.

How big do the worms get?

Mature red wiggler worms are small and thin, normally measuring between 50 and 100mm. As a comparison, nightcrawlers, which you usually find in your garden, are much larger, normally measuring between 110-300mm.

top

Can I use the worms in my backyard for vermicomposting?

No. The types of worms you find in your backyard - like nightcrawlers - are great for your garden and your backyard compost bin, but they're not suited for vermicomposting. Nightcrawlers are known for burrowing and transporting organic material deep into the soil, as opposed to decomposing surface waste. In addition, nightcrawlers will try to leave your bin if they are disturbed. Red wiggler worms are surface dwellers that are specially adapted to the environment of decomposing organic waste and don't mind being disturbed or kept in captivity.

top

Do I have to have a garden to vermicompost?

No. Vermicomposting is done indoors in a closed bin. For this reason, it's the perfect solution for apartment dwellers who want to recycle their organic waste. You can use harvested vermicompost on your houseplants or give it away as a gift.

top

Will I always need to buy new worms?

No. Once you invest in a supply red wiggler worms for your vermicompost bin, you won't need to buy any more. Red wigglers reproduce quickly and the worms and cocoons can be retained during the harvesting process for future use.

top

If my worms keep reproducing, will I end up with too many worms?

No. Although red wiggler worms reproduce quickly, you will not have an overpopulation problem in your bin. Worms will only reproduce when the proper conditions are present and populations will adapt to the amount of space and food available.

top

Do I need to get worms for my backyard compost bin?

No. You do not need to add worms to your backyard compost bin like you do with a vermicompost bin. Worms will naturally migrate up from the soil to populate your backyard compost bin. It is helpful, however, to add more worms (and other decomposers) to your backyard bin by adding a few shovels of garden soil.

top

If I cut a worm in half, will I get two worms?

No. Worms have the ability to regenerate tissue, but that ability is limited. If a worm loses a piece of its tail it can grow a new one, but a worm can't grow a new head. Worms are living creatures and should not be intentionally harmed.

top

Will the vermicompost bin smell bad?

No. The vermicompost bin will have a fresh, earthy smell. The only time offensive odors will be present is if the wrong material (like meat or dairy) is added, the bin is overloaded with food or the food is left exposed on top of the bedding, or if the compost has too little oxygen flow. Following the proper procedures will ensure your bin stays odor-free.

top

If the worms leave the bin will they get all over my house?

No. In the unlikely event that the worms do migrate from your bin, they won't get very far. You may find them alive around the bottom of the bin, where you can pick them up and place them back in the bedding. Otherwise, you may find them dried up on the floor surrounding the bin.

top

What do I do with my worms when I go on vacation?

Before going on vacation, feed your worms and, if your house temperature will drop below 15?, insulate the bin by placing a rug underneath and moving it away from exterior walls. If you will be away for more than a month, arrange to have a friend or family member take care of your bin.

top

Can I leave my vermicompost bin outside?

It is not recommended. Although vermicomposting can be done outdoors, our climate in Newfoundland and Labrador makes it a bit difficult. Worms prefer a temperature between 15-25? and don't like to be in drafty areas or under direct heat. If you do keep your vermicompost bin outdoors for part of the year, make sure it is properly insulated.

top

Can I keep my vermicompost bin in my basement?

Yes. You can keep your vermicompost bin in your basement if you keep the bin insulated from drafts and cold floors. It is, however, recommended that you keep your bin in a location where it is convenient and easy to access, like near your kitchen, where you will be producing organic waste.
