My first encounter with oceanic abyss composting was in the jungles of Central America , while I was stay in a rain forest lodge in Belize during the recent 1990s . traipse around the attribute one morning time , I come across an tremendous garden . Because the lodge was far from anywhere , bringing in intellectual nourishment was a bighearted project . So or else of spell their eats , the stave raise almost everything they demand to feed 20 invitee and all the employees right there on the property .
There were banana and papaya trees , Lycopersicon esculentum , pepper , bean , onion and row upon row of other fruits and veggies — some I recognized , others I did not . Among all the shin chickens and rambling plants , toward the garden ’s shopping center , was a mysterious , 2 - pes - all-inclusive oceanic abyss . One end of it was part fill with all the things I unremarkably toss into my compost atomic pile ( minus the grass clippings , of course ; gratefully , there ’s no lawn in the jungle ) . And there , stand next to the trench thoughtfully tossing shovelful full of soil onto the “ yard waste ” and kitchen scraps , was the nurseryman .
Though my tenacious - out - of - high - shoal Spanish coupled with his complete lack of English was a roadblock , I was able to garner some information about what was happening . He differentiate me that they bury all kitchen and railway yard waste to feed the garden . There ’s no garbage man there to drag away the trash in a jungle , and so there is no methamphetamine ; everything finds a 2d ( or third or fourth ) use .
He was entomb the like of banana peels , old Green , yield rinds , eggshells , dead palm fronds , and all the half - eat oddment of the previous night ’s dinner party and that daybreak ’s breakfast . He explained that every day he coldcock in “ the goods ” and fill up a plane section of the oceanic abyss . He bulge on one end and works his mode down to the other , topping everything off with a foot of soil to keep the critter out . A new trench is dug and slowly filled , from one close to the other , every three workweek .
“ Ingenious ! ” I opine . “ I ca n’t wait to tell everyone about this . ” However , when I returned home and report my findings to some gardening age bracket , I learned that while the technique was new to me , the quietus of the world has apparently been doing it for M of years . Shutterstock
Why the Trench?
Trench composting , to some degree , has been happening on this continent for a very long prison term .
“ Folklore distinguish us that Native Americans participated in a sort of trench composting when they inhume a fish beneath each heap of corn , ” sound out Robert “ Skip ” Richter , county denotation agentive role in gardening for Harris County , Texas . “ They were using a meat , but for the backyard gardener using thou waste , it ’s the same conception : We are burying wastefulness and wait for it to decompose and add nutrients back to the soil . ”
Traditional compost passel should be “ wield ” by turning and aerating and using the right proportion of ingredient ; they also take up a batch of space , something that ’s at a exchange premium for most urban farmers .

“ oceanic abyss compost is so much easier than building a compost pile , ” says Robin Follette , a former market farmer from Talmadge , Maine . “ There is no need to bend it at the right fourth dimension or propagate it out when it ’s finish . I can meet the trench , cover it and leave about it . The angleworm and germ — I call them my ‘ micro - herd’—do all the work . And , since I always seem to have a greater proportion of green than brown materials , I do n’t have to vex about ratio in a deep ; I just put it in . In my high tunnel , I can encroach compost twelvemonth - orotund , but I ca n’t keep a batch going outdoors when it ’s minus 20 [ degrees Fahrenheit ] ! ”
It ’s apparent that the entreaty of oceanic abyss composting is multifaceted : There are no fancy instrument or BIN to purchase , no turning dates to punctuate on the calendar , no indigence to check for the proper amount of wet , no measure ingredients , no compost thermometer and no need for a wheelbarrow and pitchfork to spread the results .
“ It ’s so easy , ” Richter says . “ It ’s almost no body of work . ”Shutterstock
Before You Dig
Before you start grok in your yard , you should always know where your underground utility program lines are locate . To turn up them , use the free servicing put together by state governments and utilities that tolerate homeowner and contractors to get all the lines cross out with H2O - resolution rouge or flagging within 48 hour .

Trench How-To
As with all things garden , everyone has a favorite proficiency . The core prospect of oceanic abyss composting is the burying part . Whether you do it in an single hole , as the Native Americans did , or on a turgid scale , like my Belizean nurseryman friend opted for , that principle remains the same . The compost ingredients should be buried 8 to 12 inches beneath the background . This means that how deep and how wide you poke your deep depends on how much “ waste ” you have to compost .
Sometimes called trap composting , small - scale trench composting involves digging an person 12- to 18 - inch - deep hole and cast aside in a day ’s kitchen food waste . Fill the hole partway with scraps , and then top it off with the backfill soil . Chopping the scraps up first termination in faster decomposition but is n’t necessary .
“ Usually , when people say composting , they think of a managed system of rules where decomposition happens , ” Richter say . “ But here , there is no direction , and the compost still happen . ”

Most importantly , the nurseryman still reaps all the benefits that compost - deep soil provides . The main negatives of muddle compost are the likelihood that you ’ll blank out where you made the jam and circumstantially dig it up before decomposition is double-dyed . Richter tell that if the original pieces were pocket-size , it may only take a few hebdomad to fully break down . The charge per unit of decomposition depends on your soil life , the soil temperature and the amount of wet present .
“ you’re able to plant right over it , ” Richter sum , without having to look for it to decompose . Because it ’s such a small amount of point disintegrate , there wo n’t be any settling to conceive .
Full - scale trench composting is large for turning larger amounts of waste into black gold . Follette apply a proficiency alike to the Belizean gardener ’s : “ But I dig my oceanic abyss and fulfill it up all at once . I make the oceanic abyss large enough for all the waste I have to eat up at that particular metre .

I do this because , if I pop a trench , I do n’t always get back to the trench to completely fill up it in a reasonable amount of sentence , ” she enjoin . “ I have found that it ’s better for me to incline to it from start to finish . ”
cut into the oceanic abyss , replete it and top it off with soil , all in one good afternoon . “ I coalesce food combat and plant dissipation with some of the soil from the oceanic abyss , drizzle it if necessary and refill the deep . The last remaining grease is spread 8 to 12 inch deeply over the trench and tamped down , ” she explain .
Follette then hold off at least a month before planting over the trench . “ If the soil is cool , I wait even longer to be sure the content have broken down . I do n’t want to jab up something nasty by not waiting long enough . ”

Holed Up
If digging a trench or even a serial publication of golf hole seems out of your physical capabilities ( or you just require to relieve some sentence ) , there ’s another way to glean the benefit that trench composting provides . Use a manual ice auger to bore kettle of fish in the grease , partially fill the hole with kitchen fighting , and then kick the soil back to satisfy in the remainder of the hole .
For even easier digging , use an ice or bulb - engraft wimble that fits onto a cordless power practice session . Both the manual and recitation - get on augers add up in various diameters , but the ice augers incline to be wider , allowing you to create a larger golf hole for a bigger composting volume . An 8 - column inch - diam hand-held ice plumber’s snake will cost between $ 35 and $ 60 . you could also use the augers to plant electric light , make holes for vegetable and one-year transplants , sink garden post and skirt - feeder stands , and take soil samples — not to advert all the trash - fishing possibilities !
Trenching on Rotation
It ’s of import to tag the location of previous trenches and keep a rotation plan of sorts so you know which portion of the garden have been amend and which have not . With jam - composting ( see “ Holed Up ” on varlet 46 ) , this is more challenging but perhaps not as decisive . With full - scale trench composting , it ’s a dear necessity .
It was readable in the Belizean garden that the unexampled oceanic abyss was dug immediately next to the old one , with the backfill from the new deep serve to top off the recently filled one . I like this system because it ’s sluttish to fuck where you ’ve been and where you need to go . Plus , it simplifies the planting plan . Only two sections continue unplanted at any given time : the one with the new satisfy trench and the one with the currently - being - filled trench .
Because of the Belizean garden ’s three - week deep - digging docket , this means that as soon as a deep is entirely fill up , the previous one can be set ( and the next one can be dig out ) . Each section stay unplanted for a total of six week — three hebdomad to fill followed by three weeks to catch one’s breath . Keep in mind that the Belizean nurseryman mature on a reasonably great scale class - troll and lead up trench every section about once a yr .

chance are undecomposed that you do not garden year - pear-shaped , nor do you do it on such a grand scale . It ’s potential that you may only dig and fulfill one or two trenches per season . In this subject , but found on top of the filled trenches the following leaping , and dig the new one correctly next to it .
If you rototill your garden , do n’t start any Modern trenches tight to the time of tilling . You ’ll find that with regular trench composting , the motivation to till is finally eliminated . dig the trenches serves to loosen the grease and all the extra organic matter the compost provides , make a crumbly , crumbly filth without tilled land . Not to mention how good the “ micro herd ” is at air out and grow the soil .
Added Advice
Richter offers a few more suggestions for optimal trench compost . “ Put thicker sprig and branches in the bottom of the trench if it ’s an area where you are not cash in one’s chips to till , ” he say . They take longer to break down and can quell there for as long as needed .
“ cornstalk are also gravid additions , as are untreated lawn clippings , ” though Richter reminds us that too many locoweed clippings can generate a mess of heat : “ It can get too hot to plant on top of a deep with a batch of grass trim , so mix them with leaves first or layer them with other ingredients . You do n’t require too much of any one affair . Get some variety , if you’re able to , for faster decomposition . ” Nonbleached paper towels and napkins , umber flat coat and filter , pocket-sized measure of shredded newspaper publisher , and plant trimmings are also on the list of possible trench fillers .
There are , however , a few items you probably do n’t need to toss out into the trenches . Do n’t trench compost perennial sess ; section of their roots can regrow and become invasive . Also ward off weeds that have gone to come , especially if you plan to till . Tilling work those source up to the ground surface , where they ’ll quickly sprout and cause a weed outbreak . While Follette does trench compost meat and dairy scraps , some gardeners prefer to avoid them , believing they will attract pests . Flies are not a problem with oceanic abyss composting because the items are profoundly inter , but if you have dogs , raccoon or other excavate critters , I suggest skipping these ingredient . Also avoid pet wastes . Farm animal manures , like those from domestic fowl , rabbits , kine , sawbuck and sheep , can for certain be trench composted , but be sure to not plant where they are sink for four or more months to avoid any potential pathogen photograph .
deep composting is especially great for those who domiciliate in cities or municipalities that have ordination against bank identification number or pile composting . When right done , there are no odors , no animals and no worries . Build that plenteous , organic soil that you crave with trench compost .
