Vermicomposting involves degradation of organic matter into fertile manure by using special type of earthworms called as red worms. The nutrient rich manure is called as vermicompost. The process of preparing manure with the help of red worms is called vermicomposting. The red worm is a type of earthworm that lives in the soil rich in organic matter. Organic soils are rich in nitrogen and carbon with plenty of moisture and microbes.
Method of Vermicomposting
- A vermicomposting pit is made with a wooden box or big cement rings.
- A mesh is spread at the bottom of the pit.
- Vegetable waste, fruit waste, waste paper which is not shiny or coated with plastic, is spread over the mesh.
- Water is sprinkled to create moisture so that the red worms can live.
- A vermicomposting pit takes nearly two to four weeks to completely convert waste into manure.
- The red worms possess a special structure called gizzards with which they grind food material. A red worm eats food equal to its weight every day. Their castings are used as rich manure. This is called as vermicompost.
- Vermicompost should be removed from the pit and dried before use.
- Vermicompost can be made in 3 -4 weeks.
- Red worms do not survive in too hot or too cold conditions.
