Vermi-beds
Scientific bed size proposed here is 10mt by 1 mt by 0.3 mt. The whole bed area should be above the ground. The bed should have a
uniform height over the entire width to the extent possible to avoid low production owing to low bed volumes. The proper bed width
should not be more that 1.5 m to allow easy access to the centre of the bed.
Land
About 750 square meter of land is required to set up a vermi compost production unit in each village. It should have at least one
super structure to cover the 40 beds. It should have an arrangement for watering and other equipments as required because
moisture is very essential for compost production. Land can be taken from Gram panchayat on lease of at least 10-15 years.
Seed Stock
This is very important thing because worms multiply at the rate of 350 worms per m 3 of bed space over a period of 6 month to
a year.
Fencing
The entire area has to be fenced to prevent the stray animals and other unwanted elements. These could be estimated based on
the length of the periphery of the farm.
Water Supply System
We have to maintain always 50% moisture content, there is need to plan for a water source, lifting mechanism and a system of
conveying and applying the water to vermi-beds. Drippers with round the clock flow arrangement would be quite handy for
continuous supply and saving on water. Such a water supply/application system requiring considerable initial investment,
however, reduces the operational costs on hand watering and proves economical in the long run. The cost of these items depends
on the capacity of the unit and the type of water supply chosen.
