Vermiculture: “The raising and production of earthworms and worm castings” In recent years, thanks to the growing awareness, the benefits of organic compost have been understood, and today, more and more farmers want organic compost as it enhances the soil fertility and regenerates micro organisms in the soil.

This idea is associated with risks of harmful organic waste to the soil, however, this can be mitigated by applying Vermi-culturing technology. Project cost is US$ 7,640, revenue is estimated at US$29,063 from production of 360 kgs of worms, which are used as baits in the fishing sector, cocoons and residues annually. The net profit margin is estimated at 3% with a payback period of 3 years.

Production Process, Capacity and Technology

Much similar to the process of making vermi-compost, this involves breeding of earthworms in a mixture of cow dung and agricultural wastes to make organic compost manure. The profiled project has a minimum capacity of 30kg per month and this, among others is on the basis of 26 working days in a month and single 8-hour work shifts in each working day.
