Vermicomposting

It is method of compositing by employing earthworms. The compost thus produced is superior to other components. The time required is also less and depends on the number of earthworms. About 4-5 kg of wastes can be composted by 1000 worms in a day.

Vermicomposting: Earthworms are Farmer’s Best Friend

Step by step procedure-

Basal Sand Layer- a layer of sand (2-3 cm thick) at the base of the tank helps in drainage of excess water and also prevents the movement of worms into deeper layers of soil.

Dung Layer- a layer (3-5 cm thick) of one-month old dung manure is spread over the sand.

Waste Layer- all biodegradable wastes are put over the dung layer. In tanks (2-3 m X 1 m X 0.5- 0.75 m), wastes can be dumped up to the brim. In heaps ( 1m width), upto height of 0.5 m, waste can be put over the dung layer.

Soil Layer- the waste are then convered with a thin layer of soil (1 cm)

Dung Layer- Above the soil layer manure dung (3-5 cm) is uniformly spread and forms the top layer in a heap or tank.

In simple words wastes are sandwiched between 2 layers of manure dung. The contents are moistened with water (at 40-50 % moisture levels) for 7 days to pre decompose the contents. After decomposition worms are inoculated [1000 worms ( 1 kg approximately) for 100-150 kg waste] and watered regularly to maintain 30-40% moisture level for better activity of worms. Watering is done in such a way that the contents of the tank or heap may not be soggy or too moist as it results in the anaerobiosis of earthworms causing mortality. To prevent evaporation during summer months, gunny cloth or straw is spread over the heap or tank. For large scale composting, thatched roof can be erected to provide shade.
