how is vermicomposting done???
Answers
Answer:
What is Vermicomposting. Vermicomposting is a type of composting in which certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end-product. It is a mesophilic process utilizing microorganisms and earthworms.
Answer:
What is Vermicomposting?
Vermicomposting is the scientific method of making compost, by using of earthworms which are commonly found living in soil, feeding on biomass and excreting it in a digested form.
Vermiculture means “worm-farming”. Earthworms feed on the organic waste materials and give out excreta in the form of “vermicasts” that are rich in nitrates and minerals such as phosphorus, magnesium, calcium and potassium. These are used as fertilizers and enhance soil quality.
Vermicomposting comprises two methods:
Bed Method: This is an easy method in which beds of organic matter are prepared.
Pit Method: In this method, the organic matter is collected in cemented pits. However, this method is not prominent as it involves problems of poor aeration and waterlogging.
The entire process of vermicomposting is mentioned below:
Aim
To prepare vermicompost using earthworms and other biodegradable wastes.
Principle
This process is mainly prepared to add nutrients to the soil. Compost is a natural fertilizer that allows an easy flow of water and to the growing the plants. The earthworms are mainly used in this process as they eat the organic matter and produce castings through their digestive systems.
The nutrients profile of vermicomposts are:
1.6 per cent of Nitrogen.
0.7 per cent of Phosphorus.
0.8 per cent of Potassium.
0.5 per cent of Calcium.
0.2 per cent of Magnesium.
1.75 per cent of Iron.
96.5 per cent of Manganese.
24.5 per cent of Zinc.

Materials Required
Water.
Cow dung.
Thatch Roof.
Soil or Sand.
Gunny bags.
Earthworms.
Weed biomass
A large bin (plastic or cemented tank).
Dry straw and leaves collected from paddy fields.
Biodegradable wastes collected from fields and kitchen.
Procedure
To prepare compost, either a plastic or a concrete tank can be used. The size of the tank depends upon the availability of raw materials.
Collect the biomass and place it under the sun for about 8-12 days. Now chop it to the required size using the cutter.
Prepare a cow dung slurry and sprinkle it on the heap for quick decomposition.
Add a layer (2 – 3 inch) of soil or sand at the bottom of the tank.
Now prepare a fine bedding by adding partially decomposed cow dung, dried leaves and other biodegradable wastes collected from fields and kitchen. Distribute them evenly on the sand layer.
Continue adding both the chopped bio-waste and partially decomposed cow dung layer-wise into the tank up to a depth of 0.5-1.0 ft.
Once, after adding all the bio-wastes, release the earthworm species over the mixture and cover the compost mixture with dry straw or gunny bags.
Sprinkle water on a regular basis to maintain the moisture content of the compost.
Cover the tank with a thatch roof to prevent the entry of ants, lizards, mouse, snakes, etc. and protect the compost from rainwater and direct sunshine.
Have a frequent check to avoid the compost from overheating. Maintain proper moisture and temperature.
