Step 1:Cover the bottom of the cement ring with a polythene sheet. (Or use the sheet to cover the ground of the area you’re using).

Step 2:Spread a layer (15-20 cms) of organic waste on top of the sheet.

Step 3:Sprinkle rock phosphate on top of the organic material (2kgs)

Step 4:Prepare cowdung slurry (15kgs) and add the slurry as a layer on top of the mixture.

Step 5:Fill the ring completely and evenly with the layered material.

Step 6:Paste cowdung or soil over the top of the material.

Step 7:Allow the material to decompose for 20 days.

After 20 days, put the earthworms on top. They will find the cracks and enter the material.

Step 8:Cover the ring with wire mesh or gunny bags to prevent birds from eating the worms.

Step 9:Sprinkle water over the whole mixture at 3-day intervals for 2 months, to maintain adequate moisture and body temperature of the worms.

* Note: when the compost is ready, it is black, quite lightweight and has a pleasant, earthy smell.

Step 10:After 2 months, (or when the compost is ready), remove the ring and heap the material in a cone shape on the floor.

Leave the heap undisturbed for 2-3 hours, to let the worms move slowly to the bottom.

Step 11:Separate the upper portion of the heap.

Step 12:Sieve the lower portion of the heap to separate the worms. They can be used again for preparation of more vermicompost.

Step 13:Pack the compost in bags and store them in a cool place.
