good luck

Earthworm good for worm composting include Eisenia fetida (Epigeic variety). They tend to congregate in the upper layers of rich organic matter and do not survive in soil that lacks OM.

A large no.of microorganisms are involved in composting and include bacteria, fungi and actinomycetes. The type of substrate and its composition is more important.

Pit size depends on the availability of space.

The moisture percent during composting process is around 50-60 %.

The temperature varies throughout the process as there occurs thermophillic (50-60oC) and mesophillic phase (30-35oC).

Philosophy of Earthworm cultivation is to feed these worms with quality and quantity food in the form of organic matter which can be easily consumed by the worms. As is the food quality so is the quality of vermicompost. This is an excellent pastime for every farmer or even for urban home gardens maintained in the backyards of individual homes across the world. We derive the maximum pleasure and satisfaction for having taken care of hunger needs of these wonderful earthworms which have been nicknamed by Aristotle as the intestines of the Earth.

Eisenia fetida (also known as: Red wiggler, or California red) is the most common earthworm species used in vermicomposting because it can be easily contained and also, it mixes its digestive excreta in the top layer of the substrate where it is grown. Temperature is a limiting factor however as E. fetida cannot survive at temperatures below 7-8 degree Celsius.

nice updates by most of workers.

Dear Zukhra,

Perhaps the manual here attached can answer your questions about vermicomposting.

Pre-composting of raw waste by bacteria is essential. During thermophillic phase temp is high. When temperature of pre-composted waste subsides to about 30o C, adult earthworms (E. fetida) are introduced.

Instead of using the term "Vermi-Composting" which reflects the objective as conversion of organic wastes as vermicompost, why not the term "Earthworm Farming" be used? The latter term indicates the objective to multiply the earthworm population by providing them food, shelter and ambience for their growth and development enormously, while their excretions become a substrate for soil biota to feed on, to improve soil fertility and productivity. Next step would be to multiply these worms in farm lands providing the required optimum facilities as food, shelter and environment for their natural multiplication, growth and development as ultimately to discontinue the earthworm cultivation under controlled conditions.
