Opportunities
and
Potentials
Vermicomposting…
…is a LOW-COST, LOW-TECH
but SCIENTIFICALLY-BASED
technology
Low cost because
materials used in
vermicomposting are
abundant and available
all over.
Example of materials that can be used:
- Grass
- Rice straw
- Corn stalks
- Cane tops
- Madre de cacao leaves
- Ipil-ipil leaves
- and other nitrogenous
materials
Low tech because the
procedure is simple…
STEPS
1. Gathering
2. Mixing
3. Shredding
4. Composting
5. Vermicomposting
6. Harvesting
Scientifically based…
because many scientists
all over the world have
attested to the
efficacy of
vermicompost.
What is Vermiculture ?

The goal is to continually
increase the number of
worms in order to obtain
a sustainable harvest.

customers who use
them for the same or
other purposes.

What is Vermicomposting?
Vermicomposting - is the
process by which worms
are used to convert
organic
materials
(usually wastes) into
humus-like
material
known
as
vermicompost.
• The goal is to process the
material as quickly and
efficiently as possible.

The African nightcrawler, known
scientifically as Eudrilus eugeniae, is the
compost or manure earthworm that feeds on
decaying organic materials. It can stay up to
the 6-inch portion of the top soil but is
dependent on decaying organic materials
above the soil for survival.

Giant Earthworm of Banawe
(Pheretima sp.)
 They are hermaphrodite and some species live
for ten years or longer.
 The optimum temperature for growth and
survival is 25 C but they died at temperatures
below 9 C and above 30 C.
 The moisture content for optimal growth is 5080% MC, with considerable decreases in
growth at 90% MC.
 All species are very sensitive to ammonia and
cannot survive long in organic wastes
containing much ammonia (e.g., fresh poultry
manure).
 They are tolerant to pH but given a choice,
they prefer more acid material, with an
apparent pH of 5.0.
Under favorable condition:
Stocked earthworms would start
mating.
Two
earthworms
bind
together in a clitellum and exchange
sperm.
Mating is done once a week.
Rate of egg production
eggs/week/earthworm.
is
3-5
The egg would be hatched in 2-5
weeks and sexually matured in 6
months.

Output
And
Indicators
When compared with soil, worm
casts also contain 1.5 times calcium,
3
times
more
exchangeable
magnesium and 8 times as many
microorganisms which promotes
healthy plant growth.
The casts are rich in humic acid,
which condition the soil, have a
perfect pH balance, and have plant
growth factors similar to those found
Application to Rice, Vegetables and other Crops
Vermicompost can
be used as Feed/s
to Swine (10 to 20
percent on
Biofeeds
Formulation)
Vermicompost can
be processed into
vemi-tea which is a
good foliar
fertilizer.
