Making Organic Fertilizer Using Lumbricus

Earthworm – Organic Fertilizer

One method of making compost from organic material is by utilizing earthworm mainly from Lumbricus rubellus type. This method is more effective than the compost method in general that relies solely on the activity of bacterial decomposers. In a worm composting system, bacteria decomposers that are aerobic bacteria remain active to decompose waste. Fresh organic waste and the resultant bacteria will be digested by earthworms.

For the manufacture of household scale fertilizer, we need equipment and materials needed.
Lumbricus rubellus worms.
Compost containers are wooden / plastic / cement boxes.
Waste organic waste kitchen, soil for bedding.
Trash cutter.

We use the earthworm type Lumbricus rubellus because it is able to live in a dense population and not dig deep into the soil. On the other side of the site we will try to discuss the introduction of various kinds of earthworms. This Lumbricus worm is a gluttonous worm.

Organic materials used in the process of making this vermicompost is the rest of the kitchen, leaves of garden waste, livestock manure, grass clippings and others. These types of organic waste will determine the speed of composting. The soft organic matter will be processed faster than the fibrous organic material such as coconut husk, banana stem. High-fiber organic materials should be chopped and soaked before use. Compost media should be arranged in between the fibrous materials and soft materials.

Compost containers with size 1 x 1 x 0.3 meters can accommodate about 20-40 kg of media depending on the type and composition of media used. Compost media can be filled from 1000 to 1500 worms. The more worms that enter the box will accelerate the process. The important thing to get attention is to keep the media moist. Humidity should be maintained at about 40% – 50%. Set pH between 6.3 to 7.5.

Environmental and media temperatures should be maintained at 20-30 degrees Celsius. When placed outdoors should be kept from the extreme temperatures of winter and summer. Protect the roof from exposure to direct sun or rain that affects the humidity and temperature of the media.

Let the worms eat the compost material into small grains. The vermicompost harvest can be done manually by spilling the contents of the compost container and allowing about 30 minutes. The worms will move to the base of the mound to avoid sunlight. Vermicompost can be picked up from the top of the mound and the worm can be moved to a pre-prepared new medium.

Vermicompost obtained in dry and sifted into netted cocoon and young worm. Young worms and cocoons are inserted into new media. The dried vermicompost is ready for fertilization.
