Explanation

Vermicomposting begins by digging a pit of about half a square metre area and one metre depth to hold the waste.

The pit is first lined with straw or dried grass and leaves to give a soft bedding layer.

Organic wastes are then added to the pit as and when they are generated.

Worm culture is introduced once bedding and feedstock are in place for them to consume.

The pit is watered once or twice a week to keep it moist for the worms.

Earthworms convert this material into nutrient rich castings used as an organic manure.
