Vermicomposting
Ideal for biodegradable wastes from kitchens, hotels etc
At household level, a vessel or tray more than 45 cm deep, and 1 x 0.60m may be sufficient
A hole shall be provided at one end in the bottom for draining the leachate out into a tray or vessel
Lay a 1” thick layer of baby metal or gravel at the bottom of the tray
Above that lay an old gunny bag or a piece of thick cloth, a layer of coconut husk upside down over it and above that a 2” thick layer of dry leaves and dry cow dung (powdered)
Lay the biodegradable waste over it
Introduce good quality earthworms into it (~ 10 g for 0.6 x 0.45 x 0.45 m box)
If the waste is dry, sprinkle water over it daily
Rainwater should not fall into the tray or vessel or box
Keep it closed
If the box is kept under bright sun earthworms will go down and compost can be taken from the top
Compost can be dried and stored
Continue putting waste into the box
Add little cow dung at intervals
Do not use vermiwash directly. Dilute in the ratio 1:10 before use
