   Q. Please send me info on the benefits of worm castings
   A. Tough question to answer. Do you wish to see some of my lab tests? The organic certificates require Fecal, Salmonella, Coliform screening. I have recent richness diversity tea analysis also.
   Many books written on the subject of worm castings. As I see it, the worms naturally take waste and decomposing materials and with the help of millions of microbes make/change that material in the building blocks of life. No man made chemical processes. Our unrestricted WA Registration means our castings can be applied directly to veggies (direct contact like potato, carrot, onions, etc) and then harvested without waiting. I tell people, to me that means you can eat it. I will get some info together and send it to you. Have you looked at the articles on our website? I am not sure what info is available that might answer your question. http://wormswrangler.com/worm_articles.html Thanks for your interest.

   Yes, Jennifer many people have more food than worms to eat it. The challenge to answer the Q. “what is 1/2 lb” is much more complicated by the fact that the worms eating capacity is used up by them re-eating existing bedding and food. Meaning if one lb of food get digested 4 times (which makes it super great) it acts like 4 lbs. Be patience, or buy more worms.

Many homeowners have some kind of home composting system in operation. However, people living in condominiums, apartments and other residences don't have a suitable place to start a compost pile. These people feel left out on a worthwhile cause, and need alternative ways to be part of the composting program.

It is called a "home vermiculture system" or "worm box system."

• A physical structure : a redworm box or container


• Biological organisms : redworms and microorganisms & macroorganisms


• A controlled environment : temperature, moisture, acidity



• A maintenance program : bedding preparation, food waste burying, separating redworms from compost and using compost

Consider the needs of redworms and needs of the owner. Redworms need controlled temperature, contolled moisture content, controlled aeration and proper pH.

Redworms tolerate a wide range of temperatures, however, the ideal temperature is between 55 – 77 degrees F. Bedding with a temperature above 84 degrees F. is harmful, sometimes fatal, to redworm populations. The temperature should be measured inside the box, because the temperature in the moist bedding is usually lower than the outside air.

Moisture Content:

Aeration:

pH level:

Owner Needs

1. Convenience for maintaining the wormbox


2. Aesthetic preferences : Kitchen? Garage? Basement? Or Bedroom??

What Kind & Size Container?

Shape:

The box or container should be shallow, not more than 1 1/2' deep. Redworms tend to feed in the top layers of bedding. Materials may pack down if spread too deep.

Size:

Size depends on the average pounds of kitchen waste per week. A box measuring 1' by 2' by 3' can handle 6 pounds of kitchen waste, which is the average for families from 4 to 6 people. A smaller sized box, 1' by 2' by 2', can handle kitchen waste for 2 people.

Material:

Never use a recycled container that might have been used for chemicals! Treated wood could be harmful, also. Some examples of good materials to use might be:

• Wooden pallets


• Old Rubbermaid containers


• Old ammunition boxes



• Go to the Re-store for ideas!

Bedding:

1. Corrugated cardboard is an excellent material for bedding. Be careful not to breathe in the dust if you shred it. Corrugated cardboard holds moisture better than any other material. Some people use a piece of corregated cardboard to cover their bedding. In a "wet" environment, it can help to absorb some liquid, and will eventually disinegrate.


2. Shredded newsprint and computer strips can be used. The papers should be shredded in long lengths of ¼" wide strips. It's easily moistened, but the strips don't keep the moisture as well. Strips provide more surface area from which the water can evaporate. They require frequent moistening. The black ink used for printing the newspaper is not toxic to redworms. The main ingredients of black ink are carbon and some oils. Colored ink should be avoided. There used to be heavy metals, such as lead and chrome, in colored ink. US Government regulations now forbid the use of heavy metals in colored ink for printing newspapers.



3. Shredded newspaper is the most economic material. Make the strips from one to two' long by ½ to 1" wide. Redworms will eat the paper after it has softened.


4. Some people may object to the initial odors of animal manures. It is not recommended to use manures if the box will be located in your living area! Animal manures have other organisms such as mites, sowbugs, centipedes or grubs that you wouldn't want in your home. But if the box will be outside or in a garage, manures would be fine. Worms really like manures. Reminder—no pet, people or pig manures!


5. Old decaying leaves are a good source of bedding. Some leaves are better than others are. For example, maple leaves are preferred over oak leaves, because the latter take longer to break down. Leaves from trees growing along heavily traveled roads could be dangerous because of possible lead accumulation on the leaves.



6. Peat moss can be used if mixed with other bedding materials. It has an excellent moisture holding capacity, however it provides no nutrients for the worms, and can be expensive.


7. A handful of soil provides the grit worms need for breaking down food particles within the gizzard. Since worms don't have teeth, their food must be broken down by muscle action in their gizzards.

Worms With "The Right Stuff"

REDWORMS:

Eisenia Foetida

This variety is the best redworm for home composting. They produce a large amount of compost in their natural habitats of leaves, manure, compost piles and in many other decaying organic materials.

Lumbricus Rebellus

This variety will adapt to the worm box environment, but they are really a soil earthworm. Their natural habitat is in soils which contain a lot of organic matter.

Redworms are on the market under many different common names. Some people call them "red wigglers," or "manure worms." Fishing suppliers may call them "red hybrid," "dungworm," or "striped worm." All these names are for the same kind of redworms. If you order from commercial breeders, your best choice is Eisenia Foetida. This variety is used by many for worm composting projects. The Cooperative Extension office has names of suppliers.

OTHER WORMS :

Worms NOT to use:

Lumbricus terrestris

This is the night crawer. This variety is the most studied of all earthworms and most sold to farmers and gardeners. They are very important for soil improvements and are widely raised for that purpose. They like to tunnel in the soil, sometimes 3 feet deep. They come to the surface foraging for organic matter, which they take into their furrows. They mix sub-soil with their food and deposit their castings on the surface. Their burrows aid in soil aeration and allow for better water penetration. Nightcrawlers have a very important role in our ecosystem but don't adapt to the shallow worm box environment.

Garden worms:

There are more earthworm varieties that might show up in somebody's garden. To identify worms you have to count the segments, study their sexual organs and their behavior. It's best to stay with redworms for your worm box.

The Sex Life of a Redworm

Hermaphroditic:

Redworms have both sexes, but mating is still necessary. If the worm has a swollen band, called the clitellum, at about one third between head and tail, this means that the worm is sexually mature. Redworms mate in their bedding at different levels, sometimes even on the surface. They may mate at any time of the year. They are attracted to each other (maybe for their beautiful body face, or other irresistible qualities.) They find each other and lie with their heads in opposite direction, bodies closely joined. They produce a secretion and secrete this through their clitella, a mucus that forms a band around each of them. Sperm from each worm move down a groove into receiving pouches of the other worm. The sperm enters in a storage sac. Some time after the worms have separated, the clitellum secretes another substance called albumin. This material forms a cocoon in which the eggs are fertilized and baby worms hatch.

Redworm cocoons are round shaped and small. They change color during their development, first white, becoming yellow, later brown. When new worms are ready to emerge, the cocoons are turning red. It takes at least three weeks for the worms to develop in the cocoon. Temperature and other conditions are factors in the development of the hatchlings. Although a cocoon might hold as many as 20 eggs, usually only 3 or 4 worms will emerge. The young hatchlings are whitish with a pink tinge showing their blood vessels.

Population Control

Conditions that determine Redworm population:

If worms have to compete for food, the population will go down. If there is a lot of food available for a time, then worms multiply at a high rate and more young worms then compete with their parents. Then this greater population produces more castings. To solve the problem you can feed them more food, but you might also need a larger box for the greater numbers of worms. It's important to note that castings are toxic to their own species, so it is advisable to harvest the castings regularly.

How many worms to start with?

The number of redworms needed depends on the daily food waste. There is a worm to daily food ratio. The ratio is 2 pounds of earthworms for each pound of food, in short: 2:1.

For example, 1 lb. Worms can eat 3.5 lbs. Food waste per week, or .5 lb. per day.

How many redworms there are in a pound of worms depends on the size of the worms. Commercial growers estimate that there are 1000 breeders (sexually mature) in one pound of worms. A dealer in baits for fishermen expect not more than 600 worms per pound, otherwise his buyers might complain. New hatchlings are very small, and sometimes 150,000 are needed to make one pound. If you order pit-run worms (worms of all sizes and ages) by the pound, you will have lots more worms than if you should order breeders by the pound.

Setting up a Worm System

You need:

1. A worm box


2. Bedding



3. A couple of handfuls of soil or sand


4. A scale, if you want to know how many pounds of food waste you have.


5. Moisture. Worms ' bodies & the bedding should have the same amount of moisture content. This amounts to 75% to 90% moisture content.

Water: Bedding ration = 3:1 by weight. Three pounds water to one pound bedding.

If using dry bedding such as shredded paper, newspaper strips or cardboard, you need to wet it. One way is to put the material in a bucket and add water to it, until it is saturated. (That would be about a minute or two.)

Manure bedding:

If using composted manures, it is more difficult to determine moisture. Be careful not to make the manure soggy! If the manure is too soggy, add some dry material to it, such as shredded paper cardboard or leaf mold. The goal is to keep your worm bin under aerobic rather than anaerobic conditions.

Moisture & Temperature:

A few drops of moisture released by squeezing could be a guideline for the right amount. If five or more drops are produced the material is too wet. The ideal temperature for worms is between 55 and 77 degrees Fahrenheit.

Adding worms to bedding:

When bedding is ready for the worms place the worms on top. They will disappear in a short time in the bedding. They don't like light. By keeping some bright light close by the box the worms will disappear faster in the bedding. If some stay on the surface after some time, assume that they are unhealthy or maybe dead, and remove them.

Food:

Most kitchen waste or table scraps, any vegetables, grapefruits, orange rinds, apple peels, lettuce and cabbage, celery ends, spoiled food from the refrigerator, coffee grounds, tea bags, egg shells are all suitable worm meals. ( Remember , no meat or dairy products belong in a worm bin.)

Don't use meat or milk products in the worm bin. Mice and rats could be attracted to the odors!

Also, non-biodegradable materials don't belong in a worm box.

Cat litter should not be used, either. The odor of cat urine is intolerable to worms, plus the ammonia in the urine could kill the worms! Cats can carry the disease Taxoplasma gondii. This can transfer to humans. For example, a pregnant woman could inhale some of the protozoan and pass the disease on to her fetus, causing birth defects.

Burying kitchen waste:

One way to manage a worm box is to pick a different spot to bury kitchen waste in the box. A 2'x2' box has approximately nine locations where you can bury wastes. That gives you nine feedings before you have to repeat the cycle.

You need some air circulating in the box, or bad odors could occur.

Worms will usually like the earlier buried food wastes. They like decaying organic wastes best. They do not always wiggle to the newly added fresh food waste. They like the bacteria, fungi, and protozoa to break it down first! Worms help keep the decaying material aerobic and help keep conditions free of odors. They produce castings at the same time.

There are many other techniques for adding kitchen wastes, which vary with owner preference and the type of box or container. Some people may just have worms in a garbage can with holes drilled on the sides for aeration. Some bury this foot deep in the back yard, and worms can come in and out as conditions vary. They just throw the kitchen wastes on the surface. (Make sure you have a tight lid that is racoon proof!) They may add some materials such as sand, soil or peat moss on top. Just be sure not to fill it too high with food and bedding, or it will pack down and may become anerobic. Whatever works for the specific situation is fine—provided there are no odors or other problems.

Grind food waste?

Grinding food waste is extra work. These kitchen wastes break down in a very short time. Eggshells should be pulverized. Although redworms have very tiny mouths, and ground food would be easier for them, we want them to help us with kitchen waste! Too much time and energy spent preparing their food can be discouraging.

Overloading the system

The size of box and amount of worms are deciding factors for how much food should be put in the box. Remember the 2:1 ratio for worms. Two pounds of worms is needed for one pound of food per 24 hours. The surface area of the box should be 7 square feet if 7 pounds of waste in one week is consumed.

If too much kitchen waste is produced on certain occasions, the wastes could be temporarily stored in another container for use later. An overloaded worm box can become anaerobic, and stinky! If that happens, don't add any fresh kitchen waste. If you leave it alone for a while, the situation will correct itself.

Do I need a worm sitter?

If you're going on a vacation, you could feed the worms a little extra just before you leave. This is the best part of having worms as pets! Feed them and leave them undisturbed. This way, you can go away for weeks. If you leave for longer than 3 weeks, it might be good to have a worm loving friend come and feed them once.

Observe the worms

The less you disturb worms, the better off they are. However, you should make regular observations to know what is going on in the box. The best time to do this is at feeding time. Is the bedding still moist? Is the temperature inside the box between 55-77 degrees? Sometimes you find many worms at one spot in a feeding frenzy. Note what they like and don't like. Look for worm eggs and baby worms. Are there any mating worms? Worms usually fascinate children. It is a good science project for children. However, point out to the children that the worms don't like to be too much or too often disturbed. They can't tolerate bright light. A red light could be practical for observations of the worms.

Different foods for different worms

Younger worms often are all congregated by a certain food item. Older worms sometimes are feeding on another. Older worms love to fill up the inside from halved grapefruits or oranges.

Recording observations

You can keep records of your experiences and improve your skills by sharing knowledge with others. Many people are interested in "vermiculture." You may be called on for information on composting with worms.

Harvesting castings and changing bedding

After weeks of adding food wastes the bedding goes down. This is a combination of worm activity and the microorganism activities. Decomposition and composting are taking place. The color of bedding becomes darker. The favorable environment for the worms decreases. The large amounts of castings might become harmful to the worms. Castings of one worm are toxic to another worm.

When to change the bedding depends on the bedding used, the quantity of the earthworms in the box, temperature and moisture conditions. Four to six months is a good guess for keeping the same bedding, if the worm boxes are correctly maintained.

Let the worms do the sorting

If you prefer only to add some new fresh bedding, carefully move the old bedding to one side of the box. Add the fresh bedding in the open space and start feeding in the new bedding.

Divide and dump technique

To divide the worms from the old bedding, dump the contents of the worm box on a sheet of plastic or a table. The worms will go down in the pile if you expose them to light. After a short time remove the top layer of the bedding up to the point you encounter worms. Wait a short time, and continue removing the bedding. You will end up with lots of worms in a small pile. If too many worms are left, some could be supplied for starting another box.

Frequently Asked Questions

Can they see?

No, worms don't have eyes. However, they must have some kind of light sensor. They are very sensitive to bright light. They will try to hide as soon as exposed. It's odd that anglers use a flashlight to catch night crawlers, since they retract in their burrows if you shine lights on them. Worms are less sensitive to red light. You can observe worms with red light. Placing a red cellophane between the light source and the worm box allows you to watch the worms.

Where is the mouth?

The worm's mouth is in the first anterior segment. There is a small protruding lip just over the mouth, called prostomium. When the worm is foraging, this lip is stretching out. The prostomium is for sensing food.

Do they have teeth?

Worms have no teeth for chewing food. They grind food in their gizzard by muscle action

How do they grind food?

Worms can only take small particles in their small mouths. Microorganisms soften the food before worms will eat it. Worms have a muscular gizzard. Small parts of food mixed with some grinding material such as sand, topsoil or limestone is ingested. The contractions from the muscles in the gizzard compress those particles against each other, mix it with fluid, and grind it to smaller pieces.

What happens to food once it leaves the gizzard?

The ground up food is mixed with enzymes in the worm's intestine. This mixture breaks down the food, molecules pass through the intestine wall into the bloodstream for use where needed. Undigested material, including sand soil, bacterial and plant residues passes out of the worm as a worm casting.

If a worm is cut in to, will it grow back?

It depends on where the cut took place. If a worm is cut at the posterior end, sometimes a new tail will grow back on. Sometimes a second tail will appear next to a damaged tail. However, the posterior half of the worm can't grow a new anterior (head.)

Do worms die in the box?

It's hard to find dead worms in a worm box, but they do die in the box. Dead worm bodies decompose very quickly, because their bodies are between 75%-90% water. If you find many dead worms you should find out the cause. High heat (above 84 degrees) is fatal to them. Too much salt or acidic food waste can kill them. It's best to change the bedding with fresh materials to solve the problem. Sometimes, partially replacing bedding may solve the problem.

How long do worms live?

Often, worms live and die in the same year. They are exposed to hazards, dryness, too hot or too cold weather. Eisenia foetida can live for as long as four years.

Do worms need air?

Worms need oxygen to live. The oxygen diffuses across the moist tissue of their skin, from the region of greater concentration of oxygen (air) to that of lower concentration (inside the worm.) Carbon dioxide produced by the bodily processes of the worm also diffuses through skin. Moving from higher concentration to lesser concentration, carbon dioxide moves from the inside of the worm's body out into the surrounding bedding. A constant supply of fresh air throughout the bedding helps this desirable exchange take place.

Composting is the age old method of turning waste materials into humus, which will lighten and enrich your soil. Sir Albert Howard, doing research in India, developed the Indore method of layered composting. This type of composting uses both methods of composting as described below in different stages of the process.
Using the outdoor large bulk pile method, it is suggested;

• a bottom layer of brush for drainage
• a 6" layer of green matter
• a 2" layer of manure
• a thin layer of topsoil (contributes micro-organisms) powdered limestone (to counter-act acidity)

Continue layers until the heap is 4 feet wide, 6 feet long, and 5 feet high. Turn every six weeks and compost will be ready to apply in two to three months.

There are two processes that take place in a compost environment;

Aerobic and Anaerobic.

Aerobic is the system utilizing oxygen. This method is the most simplistic and successful, even though the minimal loss of nitrogen through free elements into the atmosphere is present. This is the process that you want in your worm bin.

Anaerobic composting requires storage tanks and other systems to keep oxygen from invading the anaerobic decay process. Much heat generated. This process is harmful to worms. You can tell if you have this process going in your wormbin if heat and/or smell is being generated. This method also takes longer to complete and manufactures methane gas as a by-product. The odor is disagreeable, the gas itself is flammable, and should be vented off periodically. It is generally ill suited for the home composter. Some form of anaerobic composting can take place in your worm bin.
Earthworms however, are an excellent addition to the composting process. Earthworms will carefully breakdown the anaerobic microbes.

Composting is basic to the breakdown of organic materials and can be practiced on either large or small scales. The waste a family generates can be turned into nutrient rich earthworm castings for your plants, flower beds, and garden plot.
Composting involving earthworms is both aerobic and advantageous. The worms process the material, creating a micro-biological decay cycle of approximately sixty days. Home composting can include everything from kitchen waste to yard waste, but attention must be paid to what is used on your yard plantings and lawn, (pesticides, weed killers), many of which are harmful to earthworms. Many substances cannot be digested by earthworms, or are harmful to the earthworm, and it may avoid the area altogether.
It is best to introduce worms from the outside of the compost heap, giving them time to identify substances or areas of the heap that could be avoided. The internal temperatures generated in a compost heap can reach 160° F, which earthworms will avoid at all costs. Earthworms survive best in temperatures ranging from 50° F to 75° F, which is the approximate temperature of a cooled compost heap. It is easy to harvest the castings in your compost heap. Take compost from the outer edges until worms appear. Wait 30 minutes. The worms will retreat as light causes pain to their skin. Repeat the first step as many times as it takes to get a compact mass of worms in the center of the bottom of the heap. If the first outer "scalp" is not fully composted, set it aside to become the first layer of the new heap. The castings can be used immediately, or set aside for use at a later time.
Earthworms are important contributors to soil health; tilling, keeping a porous quality to the soil, allowing plants to take nutrients freely. This, combined with the auxins and cytokinins (plant growth stimulators) in earthworm castings, provides an ideal medium for plant growth and health.
Red worms are different from the common field worm, or angle worm. Red worms feed primarily on decomposing organic material at the surface level. This is why the Worm Factory works so well with the Red Wiggler (Eisenia Fotida). Field worms feed primarily on earth and bacteria contained with soil. Red worms also reproduce at a faster rate than field worms, processing and providing a larger amount of castings for your garden.
The soil, i.e. your garden, yard, or ornamentals must be amended with organic material for any worms to thrive there. Adding nitrogen fertilizers can create an acid condition in the soil that all worms may avoid. Most pesticides are toxic to earthworms and may harm beneficial insects as well.
The nutritional value of earthworm castings is best realized when mixed with soil. Even with sufficient organic matter at hand, all species of earthworms consume some soil, creating a rich humus when castings and soil are combined. The texture becomes ideal for plant growth, as many types of bacteria are consumed then neutralized by earthworms. Castings have a pH level of 7.0 (neutral). Large numbers of earthworms in your garden will combat both acid and alkali conditions in the soil. Earthworm tunneling increases water absorption and retention along with creating passages for water and air to filter through to lower levels of the soil. Most red worms are sold in bed- run form. Bed- run contains all ages and sizes from cocoon to bait size, and adapt to a new environment easier.
EARTHWORM CASTINGS
Earthworm castings are a soil amendment of the highest quality. As organic materials pass through the earthworm, many of the nutrients are made available to growing plants. An excellent organic fertilizer and soil conditioner, earthworm casts won't harm your plants through over-application. Castings as a soil conditioner make the ground friable, retain moisture, and provide nutrients. Confirmed tests have indicated that castings, when compared to native soil contain about 5 times the available nitrogen, 7 times the phosphorous, 3 times the magnesium, 11 times the potassium, and 1½ times the calcium. There are also results stated in terms of optimal values, 2 times the nitrogen needed for optimal growth, 7 times the phosphorous and potassium. This is so because earthworms, passing soil and organic matter through their digestive tracts, liberate minerals for use by growing plants. Earthworm castings cannot be compared to commercial chemical fertilizers, nor should they be.
When we became aware of the value of earthworm castings, use of commercial fertilizers ceased. The flavor and appearance of our food grown in our garden convinced us. Oh yes, earthworm castings will benefit the growth of most all plants, including weeds.

EARTHWORMS IN YOUR GARDEN
All farmers and gardeners are concerned with the "tilth" or health of their land---the condition of the soil. To be wholesome, a soil should:

1. Readily accept and retain moisture: Clay and loam soils are often too compact to let water in. As they tunnel, earthworms create channels which allow water in, minimize run-off, and drain well .
2. Be aerated: Air spaces are essential for good root growth, the growth and function of all soil organisms, and the oxidation of minerals for plant use. Tunneling increases air spaces and allows roots to spread easier. Castings help prevent compacting of the soil for additional air penetration.
3. Contain humus (organic residues): Castings are high quality humus, rich in nutrients, and are constantly being generated by earthworms. An earthworm can produce its own weight in castings in a 24 hour period. So if you have 100 pounds of earthworms, they might produce 100 pounds of castings per day!! The gardener must help by encouraging earthworms. You should allow humus to accumulate, or provide additional humus for earthworms to eat. You can do this by allowing crop remnants to remain on the ground, and by adding to it such materials as manure, grass clippings, alfalfa or grass hay, straw, and leaves. If you fail to do this, the earthworm population will decline and possibly disappear, as will the other criteria for a healthy soil. Plants grown in humus-rich soils are bigger and produce more fruitful growth'.They also tend to be more resistant to insect damage.
4. Have plant nutrients: Earthworm castings are rich in all of the essential plant nutritional elements. Studies done comparing native soils and castings show castings to be richer in every nutrient. Worms bring up additional materials and deposit them at the root level. Nutrients are always around, but not always available to the plants. Earthworms consume these unavailable minerals, and enzyme action in their digestive tracts makes them water soluble. They can then be absorbed by the plant's roots.
5. Have good tilth: Tilth is one of the most important aspects of any soil. It refers to the physical condition of the soil as it relates to ease of tillage, and,also describes the structure of the soil. A soil with good tilth is sufficiently loose in structure, well aerated, and easily penetrated by roots. It retains water better; soluble mineral nutrients do not leach off as fast. Earthworms dig deep into the subsoil, loosening it. Gradually the topsoil layer becomes deeper. Castings are excellent soil particle binders. Tiny individual mineral bits will group together into larger granules that don't compact or stick together in a gooey mass; yet retain water better. Castings also contribute to soil by giving it a more neutral pH, a measure of acid or alkali conditions.
6. Contain an active biological population: Earthworms will live in the soil if the farmer does his or her part, as in item 3. Chemical fertilizers can increase the overall acidity of the soil to a point where the earthworm populations decline. Pesticides are toxic to earthworms and many beneficial insects and micro-organisms.
