Most good garden centers sell kelp and soft rock phosphate, but it is not essential. However, it is optimum. Essential if you test the tea and compare qualities! :) |

Help with Compost Tea
Dr. Chalker-Scott of the University of Washington Center for Urban
Horticulture has written a splendid article entitled "The Myth of Compost Tea" which you can find on-line with a google search & download to your desktop as a PDF file. A lot of the "professional" advice about compost tea is driven by a "professional" desire to mis-educate the public into believing something they could very easily make at home for free cannot be made at home as perfectly or as easily as paying dearly for a gallon made at a nursery, OR requiring a lot of expensive equipment & ingredients to pull off effectively. All one needs is a water tight barrel or large can, a compost pile from which to obtain healthy sweet-smelling compost, a water hose to fill the barrel, & if you really want to be fancy, a fifty-cent aquarium stone, a dollar's worth of air hose, & a cheap aquarium pump. A typical tea vendor who was both wholesaling & retailing compost tea & tea-making equipment was giving lessons to local nurseries which he'd convinced to carry his products. He claimed that to spray fruit treas with his tea would prevent every known fruit disease & stop insects from eating foliage or fruit. His was all-purpose organic stuff -- the list of what it cured or prevented left nothing out. When a hand went up & he was informed of a Washington University and University of Washington studies that showed compost tea was worthless for the purposes he'd just outlined, without batting an eye or skipping a beat the guy insisted it wasn't HIS tea that W.U. & U.W. tested -- and HIS tea would do everything those studies indicated isn't so. One wholesaler admitted many such petty frauds exist. Then, preposterously pretending to being the only honest company, promotes the idea that in order to escape fraud, teas should be purchased only from certified brewers (overlooking the fact that there is no certification process), & the certified brewer should be asked for a required laboratory analysis of the brew (which would be a dead brew before any lab analysis could be obtained, supposing anyone really had the nerve to ask their nursery for laboratory proof that their brews were alive & well). It would be great if each vat of the stuff could be checked to see if it even had anything alive in it. When brewed from water straight from a garden hose & unaged, the chemicals added by to the county or city water supply will be sufficient to kill off many of the microorganisms, rendering the tea vastly less effective than it might otherwise have been. There are several local nurseries that fresh-brew garden teas for their customers, & not a one has any way of aging the water beforehand.So the customers lining up on Compost Tea Day are buying it chlorinated -- & if instant lab tests were possible, the microorganism count would turn out to be a mite shy of staggering. If you take a "course" designed by wholesale vendors for retail vendors to foist onto the public, you end up believing all sorts of nonsense such as: 1) these teas are good sources of nematodes (they are in the main ly good for fungal & bacterial microorganisms); that 2) there are ten kinds of tea for ten uses & ten more for ten different kinds of plants (it is not impossible to make teas that target certain predators by the addition of specific nematodes, but nothing from a nursery brewer is so formulated & they should stop promising anything more than a balance of fungal & bacterial organisms); that 3) you need fancy equipment so you might want to save on that investment by bringing in some milk bottles & buy it dearly from the nursery; that 4) it will even kill fire ants when used properly; &5) sundry other falsehoods or half-truths. Many of companies manufacturing overpriced equipment must first dupe nurseries, showing them how they WILL get filthy rich (though few ever will) promoting a mixture of bonifide & trumped up ideas about compost tea, & retailing all sorts of unnecessary products to gullible dweebs who probably THOUGHT that expensive vat wasn't necessary but were too befuddled by the dubious claims to follow that thought to the logical conclusion not to buy any of it. The wholesalers & equipment manufactures are often the exact same people who previously (sometimes still) promote vermiculture as an easy road to riches. They hornswoggled morons into believing they could get rich raising worms -- but the flimflam became too well-known & notorious so that by now only the dumbest hilljack would any longer borrow all his elderly mother's savings to buy everything he needs to be a worm farmer, believing the city dump will be buying billions of worms from him any day now for their municiple composting needs. And you too can get rich licking envelops at home. A lot of swindles went unpunished on the municiple-dumps-need-worms lie, but now the swindlers have moved on to compost tea as the latest "how to get rich selling free horseshit" gravy train. Fresh ideas, & fresh marks, were needed, & obtained. The worm farm deceptions are now compost tea deceptions aimed first at convincing the nurseries they should spend a good deal of money setting themselves up to thereafter sell dirt-water that cost them nothing & made them $5 per little squirt. The promise of obscene profits conjured out of cowshit & horseshit motivates many struggling nursery owners to let themselves be fooled before they start fooling us. What you likely won't be told when you go to the "instructional" course which is framed to teach you to be a duped customer is that good watering technique & good organic mix in the soil has a LOT more to do with the healthful microorganism population than do teas, & that adhering to a correct watering schedule & topcoating with leafmold &/or composted manures will do every bit as much as teas at keeping the microorganism population at maximum levels. The best soils around are loamy forest floors, & no one added compost teas to that -- you'd be doing your garden more good by not carting away all the grass clippings & fallen leaves than by buying tea. Overall the sales pitch posing as instruction wants to make compost tea sound like the end-all magic potion for all your problems, & without it your garden is doomed. Second they want to make it sound essential to spend a lot of money on this magic stuff, either for ghastly overpriced equipment that'll work no differently that a laundry tub dragged down from the attic, or to buy it in gallon jugs made from chlorinated water & "discounted" if you bring in lots of white plastic milk bottles for them. A typical half-truth: Compost tea prevents or cures pathogenic fungal diseases in the garden. Truth: Pathogenic funguses are less likely to invade gardens with a healthy balance of microorganisms. Horticulatural station analyses have shown that using compost teas as plant sprays for fungal defense has about the same practical value as spraying with kelp or any number of other things -- for some funguses it has no effect at all. Yet the tea vendors will want you to believe their stuff is the only good stuff. Another fraud involves compost teas used in further admixtures -- including admixtures of prepared compost teas & vinegar, which will NOT assist the microorganism population & will probably harm it. Yet another of the false claims for compost tea is that it infuses the (vegetable) garden with homeopathic & allopathic remedies, because these hornswoggling crooks do understand there is a direct connection between the belief in garden rubble as herbal magic health cures, & manure water as equally supernatural. This relative new industry will never be policed any better than aromatherapy & other crackpot ideas that people WANT to be suckered into believing. There is more value to compost tea than aromatherapy of course, but as tricked out by vendors, the very real value is mystified & expanded & riddled with fraudulant claims all designed to part you from your money -- for stuff you could've made with very little trouble for no cost whatsoever! In Canada the Canadian Standards Board's Committee on Organic Agriculture has put its sights on the compost tea industry as a bundle of petty frauds, deceptions, & intentional mis-educating methods of creating a fooled & captive consumer base -- although so far they've mainly required honest C:N ratio information (which doesn't address the primary deceptions & half-truths this dubious element of the organics industry relies on) & defines some temperatures & methodology requirements to at least keep the industry from selling toxic fecal matter to their gullible customers. In the US, alas, there is not even this moderate level of watchdogging. You being misinformed about how to treat your garden organically isn't high on anyone's consumer protection list, the attitude seemingly being that if you're dumb enough to believe your own one-gallon milk bottle filled up for $6 with dirty water is a bargain, then you deserve what you get for being dumb as a stick. Because the chemical companies have lied to gardeners for decades causing gardeners to help infuse the environment with toxins of all varieties, there's a strong desire to believe in any & all alternatives that come along. "Organic" on a product or system is so often a scam, it is simply meaningless. Compost teas assuredly have an important position in gardening, but there is no strong demarkation between the people who retailed PCBs yesterday & are now just going with what else can sell today. At least you're not being convinced to cause great harm with the particular pack of lies & half-truths surrounding compost tea salesmanship, but neither are you dealing with strictly honest people, & you may not be doing half as much good as they convinced you would happen, & at the very least you're being bilked for stuff that could be made free at home & be not one whit less effective. -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher.

This is a commercial website that promotes ideas either disproven or unproven as factual. You can find a thousand just like it, all very positive. For every two thousand sell-you-crap websites praising compost tea, you'll be able to find one actual piece of peer-reviewed science that shows the opposite to be true. Any site invested in selling you stuff is not going to provide you with the actual data of compost teas harming ground water, leaching too quickly out of soils to be of any benefit, injuring plants with excessive amounts of fertilizer, being in every regard inferior to a topcoating of mulching compost, NOT improving the microorganism content of soils, NOT repairing anaerobic soils, and for the most part not even hindering pathogenic organisms (no more than would a good soaking with pure water in any case). Not everything labeled "organic" is a good thing. The pro-Chemical lobby just hates it when "ecofundies" refuse to believe cancerous toxic chemicals are good for us & our gardens & go all insane in defennse of their PetroChemical fetish. Will greenies get just as up in arms when their favorite organic fad is found out to be 99.9% flimflam?

Help with Compost Tea
I don't buy it, I make my own, and yes, I use it the day it's ready. It takes
about 36 hours to brew and I make it when I know I'll have time to use it when it's finished. On Mon, 8 Sep 2003 15:03:40 -0700, "AnonnyMoose" opined: Well, it sells, like you say, for about five dollars a gallon. You bring your own jug and save a few cents. They fill it from the contraption it's "cooking" in. So, do you have to use all of it within a few days? Does it die if some is left in the jug for a week or so? karen "animaux" wrote in message .. . Not all compost tea is the same. The state of the art tea is made aerobically. The aerobic tea made at my favorite garden center: http://www.naturalgardeneraustin.com/ ...sells it for 5 dollars per gallon, 6 if they have to supply the jug. When diluted it can cover 7500 square feet. What you are doing is adding beneficial organisms to soil, and leaf surfaces to prevent and in many cases cure certain diseases and pest infestations. If the compost tea they sell has been on the shelf for a while, it is not aerobic tea. It also probably has some sort of bacterial suppressant so the bottle doesn't explode from the organism growth. That said, what type can you buy? On Mon, 8 Sep 2003 09:47:25 -0700, "AnonnyMoose" opined: I can buy gallon jugs of compost tea at local nurseries. How do I use it? Do I dilute it or use it straight (I'd need a ton of it!)? Is application foliar? How often do I apply? Thanks. karen "Tom Jaszewski" wrote in message .. .

Help with Compost Tea
What are you using for compost and what additioves in your recipe?
Perhaps you are making dark colored water and not ACT? I use stored bought mushroom composts and some very sweet dark liquid called molasses, mix with aged water, and pump air for two days before using it. I got the formula from a Dr.something web site that were repeatedly mentioned in many other web sites for DIY compost-tea. I don't know what "ACT" you are really referring to. Frankly, I have a feeling that whatever benefit that the compost tea can give me doesn't justify the amount of work (and electricity and noise) that I put in making it. I have a feeling that I am better off top dressing my plants and lawn with composts (if I can find a vendor that can sell compost in bulk for top-dressing my lawn). The reason is that I can see the benefit of using compost with my own eyes; but I cannot see any benefit of using compost tea. In one corner of my vegetable garden, I have dumped a large quantity of finished compost in last fall. Now, the vegetable in that corner grow taller, bearing larger fruits than the rest of the vegetable garden even though that corner of the vegetable garden receive the least sun exposure. On the other hand, I cannot see any difference from area in my lawn where I have poured compost tea for one month as comparing to an adjacent area that only receives plain water. I am not saying that compost tea has no benefit (afterall I only have applied it for one month). I am saying that whatever benefit is very small as comparing to the effort that I have put into preparing the compost tea. I really should have been spending the little time that I have left during a day to take care of my flowers, removing weeds, and to enjoy watching my garden. I am not against other people from making compost tea as long as they "feel" good in doing this. I just don't have the time in doing this especially when I cannot visually see any difference after using it. Jay Chan |

She has modified her metanalysis in "The Myth of Compost Tea Revisited," in Aug 2003. Or at least analyzed further peer-reviewed data, which I also cribbed in the other thread's list of false claims & potential harm surrounding compost tea. The data is mixed for NON-aerated compost tea's impact on pathogens, but when restricted to peer-reviewed studies, the picture is clearer: Occasional benefit is observed in suppressing pathogens with NON-aerated teas, but outcomes are not uniform or predictable so that much of it amounts to "irrepordicible science," while for others the observable benefit is equal to the benefit of watering. AERATED compost teas show none of the insinuated values for non-aerated. And surface mulching compost DOES have many of the pathogen-suppressing benefits unproven or unpredictable even for the non-aerated teas. Further, the risk to watersheds has been shown in six additional peer-reviewed articles to be very possible. That alone would be good cause to stick to the superior method of topcoating with compost mulch, which does not negatively impact the environment as compost teas could. The concepts of organic gardenings should have provable & duplicatable results to be regarded as more than empty-headed fads. By and large organic principles result in healthier gardens BY FAR compared to people reliant on pesticides, herbicides, fungicides, artificial fertilizers, & all manner of toxins. But not everything labeled "organic" is harmless or effective, & compost teas can be problems for watersheds, besides failing to function in the garden's favor in the umpteen false or unproven areas vendors claim for it beyond merely fertilizing. see: www.cfr.washington.edu/research.mulch/ Click on "Horticultural Myths" Click on "Myth - Aerobically-brewed Compost Tea Suppresses Disease - August" under "2003" Yup, to quote: Under "The Myth": "The popular press and the internet have exploded with kudos for aerated compost tea as a disease control agent. There are well over 4000 dot-com hits on the Google search engine, compared with only 1900 two years ago. Numerous magazine and newspaper articles have featured compost teas as environmentally-friendly alternatives to chemical pesticides, claiming reduced run-off into aquatic systems among other benefits." After a balanced analyes of the possible exceptions, the unduplicable science, the "best" outcomes being always from non-peer-reviewed sources, & the peer-reviewed science findng benefit in retarding pathogens equal to normal watering, & data non-aerated teas with specific qualities POSSIBLY suppressing specific pathogens, this was the "Bottom Line" of the accumulative science: COMPOST MULCH HAS BEEN DOCUMENTED TO SUPRESS DISEASE (that much is certain -- so stick with that kids!) NON-AERATED TEAS MAY BE USEFUL IN SUPPRESSING SOME PATHOGENS ON SOME PLANTS (evidence is mixed but some specific values are probable though outcomes may always remain unpredictable as to efficacy, a hit & miss method of disease control) AERATED COMPOST TEAS HAVE NO SCIENTIFICALLY DOCUMENTED EFFECT AS PATHOGEN SUPPRESSORS (and that, alas, is the aerobically brewed stuff promoted by vendors selling the teas or selling aerobic brewing equipment . So, surface mulching compost DEFINITELY GOOD, non-aerated teas POSSIBLY SOMETIMES GOOD, aerated compost teas "brewed" by nurseries or with pricy brewing eqipment NO EVIDENCE WHATSOEVER OF EFFICACY. So while some specific, limited, but good values may yet be proven for compost teas that are NOT aerated in restricting some pathogens on some plants, the thing that is unquestionable is that topcoating with compost is the proven superior method for doing the same thing. The MYTH remains: "Aerobically brewed compost teas suppresses plant pathogens." No science supports that myth. There is no evidence as yet that this is even occasionally true. Yet vendors sell it for this purpose & arrange lectures & instructions orchestrated to sell "brews" or home brewing equipment for this purpose. The additional problem of numerous outrageous false claims for compost teas from functioning as insecticidese to repairing anarobic soils to adding homeopoathic and alopathic value to veggies for human health to being a good source of helpful nematodes all stand as the extravagant flimflams perpetrated by the greedy on the naive. An additional bottom line is you can't repair damage poorly maintained soils with this alleged quick fix, whereas if ongoing soil management techniques are correctly followed, then no reason to even wish for the quick fix. That aerobically brewed soil soups can be one more of many valid liquid fertilizer is unquestionably true. It is not the best, nor the safest option, & does not do more than fertilize. But it is an option for at least that, & very likely a better option than liquid fertilizers cooked up artificially by chemists -- though that too would have to be proven. Its when the vendors get out there in left field with claiims for values beyond fertilizing that they lie or exaggerate & miss-educate, promoting false or unproven values hoping that for once crime pays & we'll give them our money for stuff not likely to be needed, & if wanted anyway, easily made at home for free without special brewing equipment (indeed, since aeration decreases its value, the aeration vats are more than an unecessary expense, they produce a tea of decreased value!) -paggers billo -- "Of what are you afraid, my child?" inquired the kindly teacher.
