this thing is not NPOV. sorry. not at all. its full of suggestions.
also how to work in actinomycetes
OK, I worked them in, because I like talking about them in my compost workshops, too. Happy now?
I've been meaning to come back and take another stab at this article, so your comments prompted me to. Best first draft I could manage with a headache & it being bedtime. Still lots more to say about active vs passive & ingredients & commercial vs home and... well... there are entire books written on this topic. ;-) On the right track?

All this technical mojo about layering and fibre is all very good, but in my garden I just sling the weeds & kitchen waste on it, wait 6-12 months and what comes out is superb. :-) -- Tarquin
same here :-) - though I've written a fairly deatiled article about compost with which I was thinking of replacing the current page with- would the original writer be offended?? Not the 1911 writer BTW quercus robur
It's best to try and merge old & new stuff together. I think this article suffers from the "scientific" approach and the "practical" approach not blending well. I suggest a short, 1 para opening, then headings for the practicalconsiderations & the scientific analysis. Or, if you like, just add your text as a new section & I'll come along and merge / separate / etc later -- Tarquin 15:06 Oct 14, 2002 (UTC)
removed POV line about compost activators; "Most of them (in the writer's opinion) are unnecessary." we could probably start a compost flame war over this, but to some extent i agree with this statement, however there are many who swear by compost activators, eg, the biodynamic crowd, also many activators (esp nitrogen rich) are indisputably beneficial, eg, urine, comfrey, lawn mowings, etc quercus robur
Nettles are good. The first spring in my current house, the garden sprouted a fine crop of nettles all over. I spent a day going round with gloves pulling them all up, and after a week the compost heap had dropped by about 30-50 cm. -- Tarquin
Hard to say how old this discussion is without digging through the history, but I think the essential point with the activators is speed. If you have time, almost anything is good enough, but to be efficient, the nitrogen rich activators really help. I am lazy and slow myself. My worms work harder than I do. WormRunner | Talk 06:31, 3 Apr 2004 (UTC)
Great page, as is humus! Seems like the two should be merged, since "compost" and "humus" are synonymous, with composting as a separate topic from compost/humus? I guess it's tricky, though: compost is usually used as a noun, but it's a verb as well... Tsavage 21:39, 3 Apr 2004 (UTC)
I was looking at that, too, and thinking about "compost" vs "composting" last night. Probably something could be done. Elf | Talk 22:09, 3 Apr 2004 (UTC)
I did some online reading, and it seems clear that compost and humus are in fact used synonymously, as far as the final product is concerned. But compost refers to man-made humus, kinda like pearls vs cultured pearls...
The best reference is Sir Albert Howard's 1943 organic farming classic, An Agricultural Testament. Howard created and popularized modern composting with his Indore method, so he's pretty much the authority. In the book, he says: "The Indore Process for the manufacture of humus from vegetable and animal wastes was devised at the Institute of Plant Industry, Indore, Central India, between the years 1924 and 1931." [1].
In the current Compost article, the separate definitions for compost and composting are already there - it's correct but not clear. I think things could be easily fixed like this:
I suppose I could just make the changes, rather than write about 'em, but... :-) Tsavage 20:10, 5 Apr 2004 (UTC)
Sorry state of the world seems reflected on this page since an addition I made last week has been removed (without a trace) although it concerns absolutely vital (trace mineral and seriously long term cycle related) compost ingredients. To wit, I added a link to David Yarrow's topsoil page with a good overview of 'rock dust' properties (understanding thereof and subsequent conscious use). I consider this (deletion) all the more offensive since rock dust is nowhere else to be found on wikipedia (anymore) and so I'd like the deleter to explain hirself asap. piet 12:49 GMT
Sorry, I'm not fond of people dismissing edits with "what a bunch of hooey," but the latest round of edits certainly is. There are *some* things that can occur in *some* compost that can affect *some* people, but it is truly a lie that backyard composting isn't recommended and that it's too dangerous for the average human to undertake. This flies in the face of centuries of backyard composting, decades of current research, worldwide use, and the general state of knowledge in the composting world. I'd want to see a tremendous amount of research literature refuting all that's gone before it. Meanwhile, yes, this article doesn't currently address some of the things that can grow in compost piles (and even in your garden without a compost pile--so look out--) and how they can affect some people. But this set of edits isn't it. Elf | Talk 21:27, 14 September 2005 (UTC)
I believe this category should be divided into two. Compost should cover the physical properties of compost its uses and applications (including references to industry standards such as the BSI PAS 100). A second article "composting" would relate to the industrial production of compost and the various associated techniques; this is of particular interest to the waste management industry. Subsections or articles such as "home composting" would remove the confusion between the technical aspects of the composting process and the readers of wikipedia interested in practical composting methods in home gardening. Here is a suggested structure:
I welcome constructive comments! -- Alex 10:58, 9 August 2006 (UTC)
Splitting into home and industrial composting is a good idea. There is no mention of "hot" garden composters (e.g. [2]) that can be used to dispose of animal waste. I think there is need for greater discussion compostable waste being collected with domestic rubbish -- there seem to be a lot of myths circulating about what actually happens to this and what can be safely added to the bin (at least in the UK). BruceMcAdam ( talk) 12:55, 9 December 2008 (UTC)
The first paragraph of this article is not correct.
Firstly, compost is what is technically called a GROWING MEDIUM.
Secondly, compost is NOT, repeat NOT a soil conditioner. Quite the opposite. Soil conditioners are used to neutralise the pH of a soil and improve drainage, aeration, and nutrient levels. Compost , especially newly dug peat compost, is acidic, low in oxygen and very compacted, and adding to soil wont improve either of them.
Soil conditioners are usually alkaline, and usually lime or farm manure is used.
I intent to rewrite this article to correct these inaccuracies. Lincolnshire Poacher 21:30, 29 September 2007 (UTC)
Hi Lincolnshire, I completely agree with the above comments. The compost and composting articles have required reworking for some time. I separated them out some time ago as I thought the process needed a separate article to the product. Happy to support and review your work as you get round to it.

This is a nice article, but it is definitely written from a European perspective. How about some facts and figures that don't reference the UK or the EU, such as an analysis of compost participation and law in the US and in non-English speaking countries. Also, how about a more extensive scientific explanation of the decomposition processes at work in composting? —Preceding unsigned comment added by 71.38.142.71 ( talk) 23:41, 14 April 2008 (UTC)
There is currently a sentence: "Modern composting originated in European organic farming in the early 20th century." with a citation. I don't have access to that citation so I cannot verify it...but the claim seems extremely bold. First of all, it's not made clear what "modern composting" is. Perhaps the source cited defines "Modern composting" in a narrow way such that the statement was true--but the current article doesn't define what is meant by "modern composting". But I was always under the impression that the practice of composting was quite ancient, and that it was only in recent times (i.e. since industrial processes to produce ammonia were developed that made inorganic nitrogen sources cheaper than organic ones) that farming and gardening moved away from using compost as fertilizer. This source: [3] says that research on composting in the U.S. began in the 1880's, and that many ancient civilizations practiced composting. On these grounds, I am removing that sentence. Cazort ( talk) 22:45, 9 August 2008 (UTC)
I think most of the comments above can be satisfied by restricting the article here to the product rather than the process, which has it's own article, not to mention the myriad others on the industrial processes .... hopefully I've done that Red58bill ( talk) 00:56, 3 March 2009 (UTC)
I'm not clear as to how I'm ignoring that definition in saying that "formulae for growing medium" (from the Innes page) is not "decayed organic material used as a fertilizer" (definition from the OED), or in saying that the Innes product simply isn't "compost" in the sense of this article .... you'd be implying peat (acidic and virtually sterile, free of beneficial microbes) is considered a "fertilizing compost" material .... I stand by the assertion that applying the term to the Innes formulations for planting mixes is idiomatic British English, and in particular, the specification of inorganic compounds doesn't fit the article or the OED (the idiom: "a mixture of compost with loam soil used as a growing medium" or the verb: "make into or treat with compost") see this policy and this one and also the info about the current useage in the UK ..... and re use of "straight" compost as a growing medium see BioHome#Usage and Biological_Wastewater_Processor Red58bill ( talk) 16:30, 21 March 2009 (UTC)
I would like to add in a section on how to compost. Not sure if that fits in the ethos of wikipedia. I do have a link for a 5 step compost that I can use. Please, let me know if I should leave as an external link or make into a section on the page. -- The Robot Champion talk to me 20:34, 16 June 2009 (UTC)
As an editor who only casually came across these two articles, compost and composting seem to basically cover the same topic. I think that readers would benefit from having one article instead of two.
Compost | Composting | Proposed merge |
# 1 Importance | # 1 History | # 1 History (?) (probably include info from "In nature") |
# 2 Materials | # 2 Ingredients | # 2 Uses (would include the information from "Importance", "Uses", "agriculture", and "As alternative to landfilling") |
# 3 Approaches | # 3 Uses | # 3 Feedstocks (include info from "in nature", materials, and ingredients) |
# 4 In nature | # 4 As alternative to landfilling | # 4 Methods (includes info from "In nature", "Approaches", "Vermicomposting", "industrial systems", "agriculture", and "standardization of products") |
# 5 Vermicomposting | # 5 Standardization of the products | # 5 Other issues/topics? |
# 6 Industrial systems | ||
# 7 Agriculture |
I think that consolidating the articles in a way similar to the above would make the topic much easier for readers to parse and editors to improve. It would also make specialized information easier to spin-off into side articles if this topic is one clear overview rather than two over-lapping overviews. NJGW ( talk) 19:39, 5 August 2009 (UTC)

The statement that the lack of microorganisms limits composting activities in land-fill sites I believe is just plain wrong. Old land-fill sites developed a great deal of heat and much decomposition took place together with the release of copious amounts of methans and carbon dioxide. Modern sites are managed to limit rainwater ingress to the absolute minimum and, if one excavates waste material in a modern site it will be found to be relatively dry. Its not the bugs that are missing, it's the water. Velela Velela Talk 09:08, 14 July 2010 (UTC)
Spontaneous combustion doesn't happen in compost piles, as the photo caption for this article erroneously claims. It's necessary to keep a compost pile moist, so those workers in the photo are watering the pile. The microbes generate a lot of heat as a byproduct of their activity--the temperatures in a compost pile can range from 150 to 175 degrees F. (in a large pile)! This photo must have been taken on a colder day, so the heat being generated in the compost pile in the photo is appearing as steam NOT smoke. I personally have seen compost piles steam on cold days! —Preceding unsigned comment added by 67.190.166.140 ( talk) 01:17, 7 August 2010 (UTC)
The more I look at this article the worse it seems. As someone who has composted for several decades I can be quite certain that early stages in an active compost heap are usually anoxic. I.e. the oxygen is rapidly used up and a thermophilic anaerobic decomposition phase starts. This is often obvious from the smell (often rather like a brewery !) but also a dissolved oxygen metre will show nil or virtually nil oxygen. It is only after this first active phase when the compost heap is turned for the first time that aerobic decomposition starts, often associated with a second more restrained period of heating.
The microorganisms present certainly include bacteria and later actinomycetes and by that stage also small nematodes, some arthropods and some annelids. However rotifers require such a thick film of water that the compost would be saturated. Rotifers occur in aerobic sewage sludge digestion and in the production of compost from such sources but I have never observed them in traditional compost. The Cornel reference from which this sentence derives is very simplistic and I think it is unlikely to be reliable.
Overall, an article much in need of some detailed research in the literature and expanding. Any thoughts ? Velela Velela Talk
Hi, I'm new to Wikipedia and didn't realize posting a link to a website that I'm affiliated with was a conflict of interest. Apologies! I'm a graduate student at Cornell and we've just launched a vermicompost research website as part of our outreach and extension for a multidisciplinary project that is wrapping up. In the FAQs for organizations I learned that I should post it here so that if other editors think it would be helpful information, they can add it. Thanks!
http://www.css.cornell.edu/cwmi/vermicompost.html
I would also like to suggest Cornell Waste Management Institute for an external link. Their site has a lot of great practical and scientific research information. http://www.css.cornell.edu/cwmi/
And forgive me if this is shameless self promotion, but there are very few scientists working in this field and I know there is a large public demand for scientifically verified information on vermicompost in general and the suppression of plant diseases in particular, I wrote a chapter in Dr. Clive Edwards latest book on vermicomposting that exhaustively reviews the available scientific literature on the suppression of plant diseases with vermicompost. I believe the whole book would be a helpful resource for this page. http://www.taylorandfrancis.com/books/details/9781439809877/

"Lady Eve Balfour who was a huge proponent of composting" Can we please stay away from these colloquially misused superlatives and remain objective?

"The reason your compost will heat up is the thermophillic bacteria works best as high temperatures." Ignoring the grammar problem, this isn't a reason compost will heat up. Rather, it's a reason one wants the compost to heat up. 99.243.22.211 ( talk) 00:26, 12 May 2011 (UTC)
As I have learned about this... composting is a form of aerobic decomposition. Bokashi is an anaerobic fermentation process. Bokashi really should only be in the see also and should be its own article 174.51.189.11 ( talk) 22:22, 5 June 2011 (UTC)

Compost Tea does not have enough nutrients in it to be used as a fertilizer, unless additional nutrients are added post incubation. Compost Tea is basically an extraction method for all the beneficial microorganisms from compost, to be applied to soil. These microorganisms then are used to 'structure' compacted soil, helping in root development, plant-micro interactions, soils transfer of nutrients and water etc. There are few reports in which the compost tea can reduce pathogens. If a correctly made compost is used (i.e. thermo-cycles and free of human pathogens), it can be used on edible plant-parts. A south African company manufactures Compost Tea for any agricultural type, but promotes a safe and quality assured safe product (look at www.ecosoil.co.za). Compost Tea can be dangerouse if made incorrectly and without much thought. Compost Tea microorganisms help to stabilise fertilizers and nutrients in soil which are lost to underground water, erosion etc. and allows farmers to reduce their fertilizer usage over folowing years. Compost tea is to be used as an aid to sustainable farming, not a solution product. — Preceding unsigned comment added by Groovanelli ( talk • contribs) 08:46, 5 September 2011 (UTC)

The statement "...world's largest composting facility once fully operational in early 2011 ... is now obsolete. It should be re-written if possible to show what happened or deleted if the result is unknown.

I found this article redirected from humanure.
I see that human fecal compost is covered in the very lengthy section of "Approaches" A) the humanure item is kind of a mess with no internal structure B) it is not an approach to composting, it is a specific subset of composting C) urine is in a completely different section
I think that it should be a separate article because: A) composting of human waste is a complex subject that is of significant worldwide environmental importance and needs it's own article. There are many approaches to composting human waste as well as detailed scientific and other aspects to document. B) the composting article is getting very over loaded.
The composting article should perhaps be refocused down to what composting means, and the general biological process / principals of composting, perhaps also a list of composting methodologies, with any substantive sub topic getting it's own article.
Having all this in one article is like having an article on cooking that, in addition to general methods of cooking, tries to cover recipes in a single section, and includes in that recipes section a sub-head called, say, preserving that then goes into the in nod outs of food reservation. It's all related, it's ll cooking, but how far into related topics do you go before they need at least a section if not a full article of their own?? — Preceding unsigned comment added by Jennpublic ( talk • contribs) 06:24, 18 May 2014 (UTC)

I just realised that there is no information on odor in this article (at least searching for odor and odour brought no results). I think this still needs to be addressed. We have more information on odour on the composting toilet page. There we wrote: "a ventilation unit to provide air to ensure aerobic conditions, to allow water to evaporate and to vent odorous gases, such as hydrogen sulfide, ammonia and methane". Gases that may develop during composting should be mentioned in this article. EvM-Susana ( talk) 11:36, 27 March 2015 (UTC)
The quality of the references on this page is generally low, I think. They are either primary sources or very old or both.
In my view, any claims should be backed up with recent (ideally within the last 5 years) secondary sources. I appreciate this is not medicine, but if we are making claims about things which impact on health (such as pathogen destruction, safety etc), we need a lot more than 20 year old studies - things have moved on and methods have improved.

This edit added information about anaerobic fermentation and silage production. I don't really see that this has anything much to do with composting.

Rather than composting (in which you need to match the carbon with the nitrogen), an alternative is to just make a deep pit in which kitchen waste can be put in (see also http://www.chowhound.com/post/bury-kitchen-waste-garden-composting-bin-684464 ). Every time kitchen waste is put in, it can be covered with a shallow layer of dirt (and/or twigs, ... if you really want to have more carbon mixed in to help it decompose quicker). I'm wondering whether this technique doesn't have a name (it's similar to trench composting, but I doubt we can call it that, since there's little or no C/N matching done). The benefit of this technique is that it's much more practical (can be done every time kitchen waste was created in the kitchen). This is something every family can do, and it also doesn't require someone to have a compost pile (which many find unattractive to have around). Once the pit has been filled, it can also be used to sow on and have vegetables growing on it. Seems useful to have a article on and/or at least an image made to show the technique.

from Manofcarbon: Much of this article is identical to section 2.15 "Compost" in "21st Century Homestead: Organic Farming" by Lamont Fedigan (2015), which postdates matching edits. It could of course have been written using Wikipedia as a sandbox, though I doubt this. I have not checked other sections in detail but am suspicious of the whole book.
If you Google the opening of the History section, you will find the above easily, and also part of an unpublished academic paper "Production of compost and its economic importance", by Dr.Sc.Isuf Lushi, University “Ukshin Hoti”, 20000, Prizren, Kosova

I have written a draft in my sandbox, which you are welcome to comment on. It focuses on what produces compost, what it is, and how it has its beneficial effects on the soil. It introduces an ecological view, in tune with current thinking that organic soil regeneration on a massive scale is needed both to safeguard future harvests worldwide and to sequester soil carbon that has been lost by agricultural practices over the past 200 years.

Should green waste (also known as yard waste) be considered as additional content on this page? In some states, green waste is no longer accepted in landfills and therefore must be composted. Also, green waste can be co-mingled with food scraps to be composted. Gram99 ( talk) 17:07, 14 April 2017 (UTC)
Green waste would belong in the Ingredients section. This suffers from inconsisent use of sub-heading levels. Some are at an equivalent conceptual level to Green waste, e.g. 2.2 Animal manure and bedding; one is not even about ingredients (Phases of composting). However green waste itself - probably the commonest class of composting ingredient - does appears more than once by implication but not by name under the more generic 2.1 Carbon, nitrogen, oxygen, water. Personally I feel that this whole section has become too bitty, with no principle for its content or subdivisions, and that's at the heart of your question.
Have you noticed that there is a Green waste stub? Filling this out first would be a good idea, with an aim to minimise what needs to be in Compost. The same principle might then be applied to other sections that obscure the Compost big picture with their detail. Manofcarbon ( talk) 16:43, 18 April 2017 (UTC)

The last sentence of the second paragraph ("When available ammonium is not used by plants it is further converted by bacteria into nitrates (NO−3) through the process of nitrification") is irrelevant and confusing at the beginning of the article. If still included in Compost, it should be moved to the 'Carbon, nitrogen, oxygen, water' subsection.
The last sentence in the Bokashi section ("Newspaper fermented in a lactobacillus culture can be substituted for bokashi bran for a successful bokashi bucket" can be removed. Wikipedia is not a How-to-Guide.
In the Animal Manure and Bedding section, "The amount of manure composted on a livestock farm is often determined by cleaning schedules, land availability, and weather conditions" can be removed as the exact amount of manure available does not contribute to the understanding of compost. -- Maw057 ( talk) 18:19, 7 November 2017 (UTC)
The 'Phases of Composting' section could be described in more detail (perhaps scientifically) to better understand the process. What is actually happening in terms of nutrient exchange and conversion?
External links to terms such as "mesophilic" and "thermophilic" should be added for better understanding. Maw057 ( talk) 05:12, 9 November 2017 (UTC)
In "Fundamentals", it says: "The most efficient composting occurs with an optimal carbon:nitrogen ratio of about 10:1 to 20:1.", citing reference 4. This is a bad interpretation of the text in the reference. What is meant there is that _finished_ compost, not the input materials, should have a carbon:nitrogen ratio in that range of values. 2001:8A0:6CC9:E801:D0AB:D0E5:51FE:7ABA ( talk) 18:09, 10 February 2018 (UTC)
