Farmersrely on earthworms to create vermicomposting systems and where the worm last and develop are the most essential part of the operation . The gain of vermicast better semen sprouting , enhanced seedling growth and increase plant productiveness . So if you ’re ready to get intovermicastand start growing earthworms , keep reading !
The following is an excerpt fromThe Worm Farmer ’s HandbookbyRhonda Sherman . It has been adapted for the web .
Types of Vermi-Systems
Let ’s take a look at the major types of vermi - systems that worm farmers are using to grow earthworms and produce vermicast . I take up with the bare — a windrow — and then hatch pit , binful , and uninterrupted flow - through bin .
Windrows
Windrows are additive piles containing bedding and feedstock that will eventually reach peak of 24 to 30 inch ( 61–76 cm ) . They are typically 4 to 8 foot ( 1.2–2.4 m ) extensive and however long the space allow for . Many people living in milder climates , such as the West Coast of the United States , have established outdoor windrows for vermicast production , though windrows can also be put up inside large buildings .

A front - end loader , skid lead , shovel , or pitchfork can be used to make a windrow . Simply go around a 6- to 8 - inch - deep ( 15–20 centimeter ) stratum of bedding of the hope width and duration on bare ground and add together 1 pound ( 0.5 kg ) of Eisenia fetida earthworms per square foot ( 0.09 m2 ) of surface area . It ’s authoritative to smother vegetation first so grass and pot do n’t grow into the windrow , which would step in with harvest time . Since compost nightcrawler do not tunnel , you do n’t have to worry about them migrating out of the windrow into the soil . After the worms have resolve into the bedding , give feedstock in a layer 1 to 11⁄2 inches ( 2.5–3.8 cm ) deep , and hold off until the provender has been consumed before adding more . During inhuman weather , 3 to 4 inch ( 7.6–10.2 cm ) of feedstock may be use to the top of the windrow to help keep the worms tender . Although many insect growers have winner with outdoor windrows , some folks describe problem with excess wet , anaerobic areas , and piranha such as groyne and birds . Vermicomposting in windrows is a ho-hum cognitive process that can take up to 12 month to produce eat up vermicast .

Pits or Trenches
Pits , or trench , have been used for decades . As with other vermicomposting systems , you repose down moist bedding , add worm , and utilize thin stratum of the feedstock on top . People like pits for vermicomposting because they are simple holes in the primer — no grammatical construction required . The earthen sides supply insulation against both hot and cold atmospheric condition . Some mass choose to line their pits with cement blocks . However , raising angleworm in pits can strain your back from bending over so often . Another disadvantage is that pits can be oversupply by heavy rains .
Earthworms consume hogget manure in the black - colored trenches inside this shelter at a hog farm in North Carolina .
A successful trench model was established in North Carolina in the other 2000s . A hogget manure vermicomposter named Tom Christenberry was having trouble with his uninterrupted stream - through bins overheating , so he create a oceanic abyss system that allow the ground to avail moderate excessively cold or spicy temperatures . Inside a pole barn he dug five deep 4 feet wide by 200 base farsighted by 21 in deep ( 1.2 × 61.0 × 0.5 m ) . Between the trenches were hardpacked shit and gravel lanes that would plump for a tractor . To bung the dirt ball , he force back a tractor straddle the top of a deep . The tractor pull out a manure spreader that was calibrated to bank hog manure into the oceanic abyss , and a worker would then apply a rake to equally spread the manure 1 column inch ( 2.5 centimeter ) deep across it . He carried out this feeding process every week using raw pig manure that had been flushed out of a barn and head for the hills through a solidness separator .
Before you commit to setting up a cavity organisation , ask yourself whether you will be capable to manage all of the deflection that it will require to apply feedstock , check the worm and bed conditions , and reap the vermicast . I used to retrieve I could work with endocarp systems , but I now realise that I could n’t deal with getting on my knees , flex over , and reaching down into the pit on a even basis .
Bins
Worm bins are a type of containment organization that can be build , buy , or repurposed . They are set up like the old systems describe — with moist bedding on the bottom , worms added on top , and then feedstock applied in thin layers on top of the bedding .

To make worm binful , worm grower often repurpose fling token , including refrigerators , livestock tanks , tubs , barrels , wooden or plastic boxes , howitzer tray , plastic buckets , washing political machine tubs , and other container . If such containers have square bottoms or side , practise holes for drainage and airflow .
Earthworm bed and bin can be progress by manus from a mixed bag of material , such as lumber , plyboard , concrete or cinder blocks , fiberglass , structural clay roofing tile , poured concrete , or brick . Wood is one of the most democratic materials , but raw wood may decompose within 4 to 10 age , depending on the climate and other constituent , so many kinfolk will hide it with plastic or coat it with raw linseed oil . Avoid using redwood , cedar tree , or other redolent woods to make the ABA transit number ; they contain tannic dose and resinous saps that are prejudicial to earthworms .
wriggle Farmer throughout the world build concrete - block binful , often on marginal ground . They are cheap , soft to receive , and wo n’t moulder . Concrete also leave more insularism than plywood , so it will keep your worm bed warmer in the wintertime and cooler in the summer .
Remember that birds love to eat worms , so if your bins are n’t lidded you should use netting to keep out avian predator . Always keep direct sunlight off the worms , too , by either locating the ABA transit number in a well - shaded area , come in them under a roof , or cover them with lid .
These MacroBins for vermicomposting at a composting installation in San Diego are the same type I use at my louse barn in North Carolina .
The worms in my Worm Barn at the Compost Learning Lab last in two MacroBins . These containers are manufactured by a company hollo Macro Plastics to stash away and conveyance vegetable . When I first saw one , I straight off thought , This would make a good louse bin ! and settle I had to acquire some . The MacroBin is constructed of impingement - grade copolymer and has smooth control surface and ventilation slots on every side , as well as the bottom . It is approximately 45 inches long , 48 inches broad , and 34 inches high on the outside ( 1.1 × 1.2 × 0.9 m ) . The interior of the bin is approximately 41 inches by 45 inches by 29 in ( 1.0 × 1.1 × 0.7 m ) . It can hold 1,300 pound sign ( 590 kilo ) of materials and can be lift by a forklift from any side . The MacroBin costs about $ 230 , with discounted rates for bulk purchases . I was n’t cognizant of anyone else using these agricultural bulk containers as worm bins until I saw 10 of them set up up for vermicomposting while touring a compost site in San Diego !
Garry Lipscomb and Bill Corey , the owner of NewSoil Vermiculture LLC in Durham , North Carolina , made bin out of fictile 55 - gallon ( 210 L ) drums for the commercial operation in the basement of their house .
Many louse farmer repurpose plastic IBC totes ( medium bulk containers ) to make worm bins . They are orotund tanks used to store and transport 275 to 330 Imperial gallon ( 1,040–1,250 L ) of liquid or bulk cloth . IBC totes be less than $ 150 new , with interlingual rendition domiciliate within metal cages usable for approximately $ 100 more . These tankful are being repurposed for a diverseness of role , so it ’s pretty easygoing to take them used at a lower price .
