Mary Appelhof, author of Worms Can Eat My Garbage (Flower Press,
1982) describes a system called vermicomposting. This system
includes raising worms, producing rich compost that is very
beneficial for plants, and disposing of kitchen waste all in one.
Find A Suitable Place
The worms and bedding should be
contained in a small box or bin, approximately one foot high, 2
feet deep and 3 feet wide, so you'll need that much space.
Temperatures of about 60 to 80 degrees F. are ideal, but the worms
will tolerate temperatures from 40 to 90 degrees F. You'll want
the location convenient to your kitchen to make disposal quick and
easy. Even though a properly maintained bin is odorless, most
would rather not have a box of worms inside their house. Most
people prefer a basement or garage location.
Purchase Or Build A Container
The worms aren't too picky about
housing, so mainly consider what suits you. Some people prefer
building a box usually with the dimensions mentioned above. If you
decide to build your own box, use exterior grade plywood and
construction grade lumber. Don't use pressure-treated wood for
those parts on the inside surface, as the chemicals may be toxic to
worms. You can paint or stain the exterior of the box, but leave
the inner surface unpainted. Be sure to drill at least twelve 1-inch holes in the bottom of the box for drainage.
Prepare The Bedding
Commonly available sources of suitable
bedding for your worm bin are shredded newspaper, cardboard, or
computer printout paper. Knowing someone in an office with a paper
shredder is helpful, but you can easily shred your own paper. With
newspaper, use only the regular black and white sections - not the
color sections - as dyes maybe toxic to worms. Tear the paper
along the center fold, then keep tearing in parallel strips of
about 1 inch in width. You'll need about 10 pounds for an
average sized bin.
Put the shredded newspaper in the bin. Add a gallon of garden
soil-the worms need the grit to aid their digestion-and 4 gallons
of water to provide sufficient moisture. The bedding material
should be moist but not soggy. Prepare moistened bedding at least
2 days prior to adding worms, as it may heat initially and harm the
worms.
Get The Worms
These worms are commonly raised for fish bait and
can be readily purchased locally for stocking. You'll need
approximately 2 pounds of worms for each pound of garbage your
household produces daily. For example, if you are stocking one
worm bin and your household generates one pound of kitchen waste a
day, common for an average household of four, start with 2 pounds
of worms.
Caring for the worms is easy. Spread the worms gently over the
top of the prepared bedding. They can be fed on plant-derived
products such as potato peels, lettuce leaves moldy bread,
spaghetti, orange peels, tea or coffee grounds, and garden waste
like corn shucks or pea shells. Large amounts of meat or bones can
cause odors and attract dogs or rodents and should be avoided.
You can feed the worms every day, twice a week, or only once a
week. Let your schedule, not the worms, be your guide. If you're
going to be away from home for more than a month, you may wish to
have someone feed the worms for you. To feed your worm bed, push
back the bedding, place the food, and cover it so that it's an inch
or so beneath the surface. There's no need to chip or grind the
food; let the microorganisms and worms do that for you.
If you place the garbage in sequence at different locations in
the bin over the course of several days, you won't come back to the
same place twice and thus will avoid a disagreeable encounter with
freshly decomposing garbage.
You'll need to change the bedding and harvest the larger worms
after about 2 months and every month or so thereafter. To harvest
the worms, you can dump them and the compost onto a piece of
plywood in a cone-shaped pile. In a few minutes, the worms will
move into the pile to escape light and exposure. At this point,
you can remove the top few inches of the pile, wait a few minutes,
and repeat. Eventually, you will be left with a pile of mostly
worms. You can harvest the large ones for fish bait and return the
small ones and the egg cases to a freshly prepared bin with new
bedding.
Use the old composted garbage and bedding as a nutrient-rich
soil amendment around plants or in your garden.
Worms move by the powerful stretching and pulling strength of
their muscles. They detect light from dark and are very sensitive
to vibrations in the soil. Each worm bears the reproductive system
of both sexes, but two worms must mate for reproduction to take
place.
Redworms consume large amounts of organic matter and are found
in manure and compost piles and decaying leaves. They live closer
to the surface than earthworms and reproduce very quickly in
captivity. Eight redworms become 1,500 redworms in six months!
Commercial Earthworm Production
Introduction
Many Texans are interested in raising earthworms as a hobby,
for their own use, or as a source of income. Much interest in
vemiculture (worm raising) has been kindled by extravagant claims
of enormous potential markets for earthworms in agriculture, in
large scale waste disposal systems, and as a source of food for
animals and even people. The major use of earthworm today is as
bait for freshwater sport fishing. Some worms are also sold to
home and organic gardening enthusiasts for soil improvement and
composting of organic refuse. Although research and development
activities relating to other uses for worms are underway in various
places, the opening of new markets for worms and castings will be
slow and somewhat uncertain. Thus, anyone interested in the
earthworm business should explore the potential local markets
carefully, particularly if a full-time occupation is contemplated.
Some earthworm wholesalers sell breeder stock to new growers and
promise to buy the worms back from the grower at a "going wholesale
price." These wholesalers then resell the worms to bait shops,
home and organic gardeners, and other users. Such an arrangement
could help a new grower market his produce, but his success would
depend almost entirely on the wholesaler's honesty and ability to
meet his obligations to the grower. Prospective growers
considering such an arrangement should check carefully with their
local Better Business Bureau and Chamber of Commerce, and also with
the wholesaler's other growers or customers, to determine his
reputation before entering into a contract.
Establishing an earthworm-business should not be done on a trial
and error basis. Earthworms are a form of livestock and there are
certain minimum requirements of care that must be met on a regular
schedule. New earthworm growers should consider entering the
business on a small scale and learn to raise worms successfully
before attempting mass production.
Taxonomy
Earthworms are scientifically classified as animals belonging to
the order Oligochaeta, phylum Annelida. In this phylum there
are about 1,800 species of earthworms grouped into five families
and distributed all over the world. The most common worms in North
America, Europe, and Western Asia belong to the family Lumbricidae
which has about 220 species. Earthworms range from a few
millimeters long to over 3 feet, but most common species are a few
inches in length. Only a few types are of interest to the
commercial earthworm grower, and of these only two are raised on a
large-scale commercial basis. Some of the more common species used
for bait are:
Nightcrawlers. This earthworm is common in the northern
states and may be picked from fields and lawns at night for
commercial fish-bait sale. Although very popular with fishermen,
they are not commonly raised on a commercial basis because they
reproduce slowly and require special production and control
procedures.
Field worms (also known as garden worms). These make
excellent fish bait and are often preferred by those who want a
small number of worms for their own use. They are not prolific
breeders and are not recommended for commercial purposes.
Manure worms (red wigglers). These are particularly adaptable
to commercial production and are commonly grown by successful worm
farmers.
Red worms. These are basically another type of manure worm,
differing mainly in size and color from their larger and darker
cousins. They are adaptable to commercial productions and together
with manure worms constitute about 80 to 90 percent of commercially
produced worms.
Manure worms and red worms can adapt to living in many
different environments. They will eat almost any organic matter as
well as many other types of materials which contain organic
substances that can be ingested.
Worms are present it manure piles or in soils containing large
quantities of organic matter, but the new grower should purchase
breeding stock from a reputable grower or distributor.
Biology
Because the physical structure of earthworms varies only
slightly from one species to another, a description of one species
will apply in most respects to any other. Lumbricus terrestris, is
used for descriptive purposes.
The earthworm, while primitive, has well-developed nervous,
circulatory, digestive, excretory, muscular, and reproductive
systems. The most noticeable external feature is the ringing or
segmentation of the body, which involves nearly all of the internal
structure. The nighcrawler has about 150 segments, while manure
and red worms have approximately 95. Segmentation within the
earthworm serves the same general function as the division of the
animal body into organs --that is, different segments perform
different functions.
The first section of the earthworm consists of the mouth and
the prostomium, a lobe which serves as a covering for the mouth and
as a wedge to force open cracks in the soil into which the
earthworm may crawl. Small hair-like structures, called setae, are
located on each segment. These can be extended or retracted for
movement. The worm's lack of protruding structures other than
setae facilitates efficient burrowing; in addition, various skin
glands secrete a lubricating mucus which aids movement through the
earth and helps to stabilize burrows and casts.
The earthworm's digestive tract is adapted to its burrowing
and feeding activities. The worm swallows soil or residues and
plant litter on the soil surface. Strong muscles mix the swallowed
material and pass it through the digestive tract as digestive
fluids containing enzymes are secreted and mixed with the
materials. The digestive fluids release amino acids, sugars, and
other smaller organic molecules from the organic residues. The
simpler molecules are absorbed through intestinal membranes and are
utilized for energy and cell synthesis.
Earthworms lack specialized breathing devices. Respiratory
exchange occurs through the body surface.
Reproduction. Earthworms are usually not self-mating although each
individual possesses both male and female reproductive organs. A
mutual exchange of sperm occurs between two worms during mating.
Mature sperm and egg cells and nutritive fluid are deposited in
cocoons produced by the clitellum, a conspicuous, girdle-like
structure near the anterior end of the body. The eggs are
fertilized by the sperm cells within the cocoon, which then slips
off the worm and is deposited in or on the soil. The eggs hatch in
about 3 weeks with each cocoon producing from ten to twenty worms
with an average of four.
Earthworms and soil productivity. Numerous investigators have
pointed out the beneficial effects of earthworms. Some of these
are as follows:
- They aid in the degradation of organic residues in the
soil with the release of elements such as carbon,
nitrogen, sulfur, and other nutrients.
- The action of the digestive fluids and increased
microbial activity in the casts (droppings) tends to
solubilize inorganic plant nutrient elements present in
inorganic soil minerals.
- The structural stability of ingested soil is improved
through increased microbial activity while the soil is
within the work and after it has been deposited as casts.
- The extensive burrowing of the earthworm improves soil
aeration and may increase water penetration into soils.
- Under natural conditions the earthworm will feed on
surface organic litter and deposit its casts in the plant
root zone. After further microbial decomposition of the
partially digested residues, plant nutrient elements are
released.
Although earthworms are considered beneficial to soil
productivity or plant growth, few valid studies have been made to
determine whether their presence will significantly improve plant
growth. In one study Hopp and Slater (1949) found that growth of
clover was improved by earthworm activity in a poorly aggregated,
clay-type soil, but in another study Chadwick and Bradley (1948)
were unable to demonstrate increased crop productivity. More
studies with a variety of soils and plants are needed to further
elucidate this. However. other soil organism and plant root
activity may exert the same or similar beneficial effects on soil
properties and positive results may not be expected in all soils.
Before attempting to "improve soil through the addition of
earthworms, remember that earthworms are a natural component of
properly managed soils. If more worms are needed a food source
must be provided and lime added if the soil is acid. Such
additions of worms should be a one-time operation and not an annual
situation to base a business upon.
Earthworm Castings
Castings are a natural by-product of earthworms and are rich
in organic matter, and nutrients for plants. When added to normal
soils in gardens or lawns, they will provide the same kinds of
benefits as other bulky organic fertilizers. The nutrient value of
the casts will be dependent upon what organic materials are being
fed to the worms. Generally the casts should be roughly equivalent
to a compost prepared from the same organic materials less what was
removed within the worms harvested. Castings today are not
commonly used as fertilizer by large commercial plant growers,
because their cost is relatively high compared to other fertilizers
containing the same or greater amounts of nutrients. However,
castings are used by some organic gardeners, and are sold
commercially in a few nurseries as a sold amendment or planting
medium for ornamental plants grown in baskets or flowerpots.
Earthworms as Food or Feed Supplements
Approximate analysis of earthwoms was completed by Dr. Carl
Cater in the Oilseed Products Laboratory at Texas A&M. He reported
that on the samples tested moisture (volatile) averaged 80.44%. A
further analysis of freeze-dried earthworms indicated the following
components: oil 6.8-7.1%, nitrogen 10.6 - 11.0%, protein 66.2 -
68.6% and ash 9.3 - 9.7%. This would indicate that on whole, live
earthworms are less than 14% protein. Therefore its use as food or
a feed supplement would probably be limited. It should be noted
that the freeze-dried product (after water is removed) compares
favorably with defatted soy flour from the standpoint of amino acid
availability. Further research may lead to the use of earthworms
as a food supplement but this use is at best only a potential
market.
Production
The basic environmental factors which affect earthworm
breeding, growth, and general health are: temperature, moisture,
aeration, food material, and ph (acidity-alkalinity).
Temperature. Earthworms will die in freezing temperatures, so
they protect themselves by moving to lower depths in growing-beds
or soils. They will live and breed at temperatures up to about 85
or 90 degrees F. For commercial earthworm production, ideal
temperatures for growth and activity range from 60 to 80 degrees F.
For intensive cocoon production and hatching, bed temperatures
should be between 60 and 70 degrees F.
Moisture. Earthworms require adequate moisture for growth
and survival. Beds should be crumbly moist, not soggy wet. They
should not be exposed to direct sunshine. To enhance cocoon
production after worms are fully established, beds should be
allowed to dry until the top 2 inches are barely moist. Then
sprinkle sufficiently to restore normal moisture content.
Aeration. Earthworms can live at relatively low oxygen and
high carbon dioxide levels, and can survive in oxygenated water.
In the complete absence of oxygen, however, they may be adversely
affected or may die. Oxygen may be depleted if the beds are kept
soggy wet -- under such conditions anaerobic bacteria may produce
toxic substances.
pH(acidity-alkalinity). Earthworms will grow over a pH range of
4.2 (acid) to 8.0 (alkaline). For commercial production, however,
it is best to maintain a pH of 7.0. Check pH regularly with litmus
paper or a pH kit, which is available in most feed stores. Ground
limestone may be mixed with bedding material to correct acidity.
Lights. In periods of high humidity and warm temperatures,
worms may tend to leave the beds. Lights placed over or around the
sides of beds will discourage such movements. This is especially
helpful during violent storms and high rainfall.
Beds. Frames for earthworm beds may be constructed of almost
any convenient material. For large-volume production large
rectangular troughs are best. These worm beds may be constructed
on concrete block, brick, pine or cypress boards on the ground, or
they may be placed on a concrete slab. If you use pine or cypress,
use at least 2-inch thick boards. Any convenient length is
satisfactory, but the width should not exceed 30 to 40 inches,
which permits reaching the center of the bed when harvesting the
worms. The sides of the worm bed should not exceed 18 inches in
height, and the worm beds should be separated by a walkway to
permit easy harvesting. For better temperature control, the
frames or containers should be partially buried in the soil. The
worms can also be grown in pits in the ground or in row piles on
the soil surface. Outdoor beds should be located in a well-shaded
spot or under an open-shed roof. Indoor beds should be placed
where there is adequate drainage and ventilation. A bed 8 feet
long by 3 feet wide by 1 foot deep, will accommodate about 100,000
bed-run earthworms or approximately 25,000 mature breeders. While
some growers consider these numbers excessive, such levels are
recommended for forced breeding and increased production. The beds
must be thinned out by harvesting about every 30-45 days or by
dividing every 60 to 90 days.
Bedding materials. A good earthworm bedding material should
retain moisture, remain loose in the pile, and should not contain
excessive amounts of high protein or other readily degradable
organic nitrogen compounds. These compounds would be quickly
degraded with the release of ammonia and temporarily increase the
pH of bedding material.
Almost any organic residue material, including plant wastes
and most bulky animal manures, are suitable for bedding. Some
growers mix sandy loam topsoil with the bedding material, but this
is not needed and will increase handling time or costs and may
decrease yields. Horse and rabbit manures are considered to be
ideal.
If the bedding material contains high amounts of carbohydrates
and other organic substances, it may heat in the beds. Under these
conditions, temperatures inside the pile can reach 150 degrees F.
or higher, which will kill worms or they will leave the beds.
Therefore, materials of this type should be composted beyond the
heating stage. This is accomplished by making a flat-top pile or
piles, moisture conditions, and to return organic material on edges
and top to the middle of the pile(s). When the heating stage has
passed, material should be well-mixed and finely chopped. If the
material is too coarse the earthworm will not be able to digest it
and poor growth will result. High salt concentrations may reduce
cocoon formation and worm body weight, so after aging the bedding
material should be leached to remove excessive salts. After
leaching, keep bedding material moist but do not flood, and check
the temperature of the bedding material. If it remains below 80
degrees F. after 5 to 6 days the beds may be stocked with
earthworms.
After worms are added, bedding should be kept moist but not
soggy and the top 6 to 8 inches turned every 7 to 10 days to keep
it loose.
About every 6 to 9 months the old bedding should be replaced
with properly prepared new bedding. To change bedding, remove the
top 5 or 6 inches (where most of the worms are). Harvest the worms
remaining in the bed. Then remove the remaining old bedding
(castings) and refill bins with new bedding, replace the top layer
including the worms, and continue feeding.
Feed and Feeding. Animal manures, garden compost, shredded or
chopped cardboard, wood or papers or almost any decaying organic
matter or organic waste product may be used as feed or to produce
feed for earthworms. Dairy, steer, horse and rabbit manures are
excellent feeds. Low-nutrient feeds need to be supplemented with
high protein or nitrogen materials such as grains, mashes, walnut
shell meal or cotton seed meal. The feed and supplements can be
used straight or can be mixed with 20 to 30 percent horse manure or
old pine or fir wood shavings, and spread on top of the bedding in
thin strips or patties. This method of feeding will draw the worms
to the top of the beds where they may be harvested most easily.
The protein content of the total feed should not be less than
9 percent and no more than 15 percent. If too little protein is
present worms do not grow well, and the beds become too acid for
eggs to hatch. With too much protein, feed decays quickly and the
beds become too hot for the worms. Soured beds become filled with
maggots from flies. Using feed with about 10 to 12 percent protein
gives best results. If reasonable care is taken not to overfeed,
worms can be raised without growing flies.
Worms should be fed regularly, usually once a week. The best
guide to feeding schedules and amounts is condition of the worms.
When the last of the feed is almost gone, it is time to feed again.
Fattening earthworms. Earthworms may be force-fattened so
that their girth and weight double. A good method is to prepare
several new beds with 6 inches of bedding and soak until soggy wet.
Harvest the regular beds, place the harvested worms in the
fattening beds, and feed them straight mash or meal. If they are
very active, feed them twice daily. A formula that has given
excellent results is as follows: 700 lbs corn, 500 lbs. oats, 200
lbs. Milo and 600 lbs. alfalfa pellets. This formula contains
about 12-15% crude protein. Additional cottonseed meal is often
added by experienced growers but can result in sour beds. The
worms will be ready for harvesting and selling in 7 to 10 days.
Harvesting. Earthworm beds should be harvested on a regular
basis to ensure maximum worm production and minimum disturbance of
beds. Regular harvesting (usually every 30-45 days) thins out the
population, allowing remaining worms more feed and keeps bedding
loose and porous so the worms can move about more easily.
One harvesting method commonly used is known as "table
harvesting". A table or board placed next to or across the
worm-bed frame and covered with waterproof plastic will serve the
purpose. One or more containers for the harvested worms, and about
2 inches of pre-soaked peat moss for the bottom of each container,
will also be needed. Use a pitchfork to carefully lift off the
top 3 or 4 inches of bedding and place it into the harvesting
board. Harvesting should always be done in bright sunlight or
in the light of a bright overhead bulb. The worms will burrow
down nearer the bottom of the bedding to escape the light. Using
either your hands or a small broom, gently sweep off the top of the
bedding pile. Wait a few moments for the worms to burrow down and
then repeat the process. When all the bedding has been swept off
the pile, a solid mass of worms will remain.
If many beds are to be harvested, speed the process up by
first placing the bedding material in tubs. At intervals remove
the top soil from the tubs and return it to the beds. When only a
few inches of material remains in the tubs, combine them and pour
the contents onto the sorting table.
There are several machines on the market today to harvest
earthworms. Though the price of these is high, several growers may
own one together or some contract harvesting is available in urban
areas.
Grading and counting. Earthworms are sold by weight or by
count, and there are two grades: bed-run (worms of all sizes) and
bait-size (worms 2 inches or longer when drawn up and with
bodies at least 1/8 inch in diameter). If worms are to be sold for
bait, sort out the bait-size worms by hand or machine and put the
smaller worms back into the beds.
Packaging and storing. Earthworm growers use a wide variety of
packaging methods and containers, but more and more successful
growers are using containers especially designed for holding and
shipping worms. Such containers are available from various
suppliers, and can often be purchased from an earthworm wholesaling
company or distributor. Containers range in size from half-pints
(holding 50 bait-size worms) up to gallon cartons holding 1,000
bait-size or 1,500 to 2,000 bed-run earthworms. Containers should
be made of plastic or wax-coated cardboard to retain moisture and
resist eating by worms. Small holes should be punched for air.
Worms should always be stored in cool, well-shaded locations.
Boxes should be securely tied or fastened with heavy shipping tape,
and clearly marked on the outside: LIVE EARTHWORMS. HANDLE WITH
CARE. DO NOT EXPOSE TO EXTREME HEAT OR COLD.
Selling the worms. A contract grower for an established
wholesaler will have a steady market for the bait-size worms. To
make higher profits, however, many new growers decide to go into
the business either as independent wholesalers or retailers.
Sales may be made to locally-owned sporting goods or fishing
tackle stores. Earthworms can be sold by mail by placing a
classified advertisement in one or more of the national magazines
directed to fishermen or to organic gardeners. Pet shops selling
birds or fish may buy worms as food items. High school and college
biology classes use worms for dissecting, but this market is
difficult to enter.
Since the demand for fishing worms is quite seasonal,
relatively few are sold from November through March. While the
fall months also are excellent sale periods in Texas, the heaviest
demand develops during April, May and June.
Earthworm Pests and Diseases
Earthworms are subject to attack by a variety of pests. Most
outbreaks are the result of poor bed management. However,
information on the full significance of the relationship between
earthworms and their predators and parasites is scarce. Earthworm
enemies include ants, springtails, centipedes, slugs, mites,
certain beetle larvae, birds, rats, snakes, moles, mice, gophers,
toads, and other insects or animals which feed on worms or molest
them. The earthworm has a number of internal parasites including
numerous protozoa, some nematodes, and the larvae of certain flies.
Larger predators can be excluded from worm beds by proper
construction of the bins, and by use of screens or gratings at the
bottom and top of beds. Mites, springtails and ants are of
greatest concern to the earthworm grower.
Mites. "Red mites" or "fishworm mites" frequently become a
limiting factor in worm production. They are natural inhabitants
of manure and similar organic materials and all worm beds contain
low-level populations of mites. Several species of mites are
present in most worm beds, but the most important is the earthworm
mite. These brown-to-reddish mites are small, although readily
visible. They are found most abundantly near the surface and edges
of worm beds and around feed concentrations. They do not normally
attack earthworms, but they do consume worm feed. When mite
populations are high, worms will stay deep in the beds and not come
to the surface to feed, resulting in poor worm-growth and
reproduction.
Control. The best control for earthworm mites is proper
management. High mite populations are nearly always associated with
one or more of the following conditions. (1) over-watering, (2)
over-feeding, or (3) feeding of wet or fleshy garbage. Bed
conditions ideal for worm production are not conducive to high mite
populations. Feeding schedules should be maintained so that feed
is consumed in a few days, thus preventing accumulations of
"soured" feed in the beds.
Worm beds with poor drainage frequently become too wet,
creating conditions less favorable to worms and more favorable to
mites. Watering schedules should keep the beds moist but not wet.
High mite populations are frequently associated with the
feeding of garbage, and other vegetable refuse having high moisture
content. Such feed should be used with discretion.
When mites start to build up, uncover the beds and expose them
to the sun for a few hours. Cut down on feed and water. Till the
beds and add calcium carbonate every 1 to 3 days. When mites or
other insect populations build up in the beds, some growers attempt
to reduce them by a heavy watering to force the pests to the
surface and then burning them with a hand-held torch. However,
physical or chemical removal of mites will be only temporary
benefit unless bed conditions are altered to create a
less-desirable environment for the mites. Chemical control of
earthworm mites is suggested only as a temporary control measure
until bed conditions can be altered.
Ants. Ants can be kept from the worm bed by dusting the area
around the bed with pyrethrum dust whenever ants appear. As ants
are attracted to feed, remove any that is spilled in the vicinity
of the beds. Do not use any soil in the worm beds that might
contain insecticides. If ants are found in the beds, saturate that
area with water and they will usually leave the bed.
Springtails. Springtails are small, white to gray, oblong
insects that jump when disturbed. They can sometimes become
abundant enough to turn the surface of the bed white. Their
greatest harm is feed consumption, but they have been observed to
attack and consume weak or dead worms. When springtails are abundant,
worms stay deep in the beds and refuse
to come to the surface to feed. Control procedures are the same as
for mites.
White worms.A small, white threadlike worm called a
planarium (Bipalium sp.) is often found in the earthworm beds. It
is common in fecal material and eventually gets into worm
production beds via manures. This species does not appear to be
parasitic or harmful to the earthworm, but will utilize some of the
feed material.
