I think it was a lot of big anecics (those with the ring) very similar to those on your photos ... I should have taken one ...

Here are the "wankers" of my compost, as Did would say! : Cheesy:
worms from compost.jpg


They are fairly fine red worms of about ten centimeters, fluted with small yellow rings, and very lively: they wiggle like maggots as soon as the compost is stirred.
As Did explains, they are surely wankers for the soil, but to degrade the organic waste of the compost, they are rather effective! ...

Besides, in the end, is there a difference in the quality of compost depending on the worms that degrade it?

The "wankers" are often very pleasant people ... You invite them, they "degrade" a lot of biomass: fries, spaghetti, sausages, sauerkraut, everything goes ... On this ground, they are very effective , I agree with that. It's when you need a helping hand that it spoils!

As long as I think that composting in heaps is not a good thing for a "Lazy Potager", I am not interested in them. I want my good food (hay) to stay for the anecics, who work for me ... They are my real friends ...

For those who want to do vermicomposting, of course, they are effective, for that!

Quite honestly, I don't know. Never read anything on the subject ...

Indeed the epigés have little interest in a large vegetable garden if not to quickly degrade the organic matter (remains of crops, peelings, damaged fruits or vegetables left on the surface or covered with hay) but I noticed (with little I concede that they disappear as soon as the job is done, as soon as the humidity is lower ... and as soon as they find better elsewhere.

They are opportunistic copulating gnaws.

Jean-Marie Lespinasse, of which I recommend the latest book, uses them as a mini factory to break down organic matter and produce a vermicompost on which the plants in his kitchen square feed.
For this he makes a small square excavation in the center of each of his vegetable squares, lined with pieces of cardboard and regularly garnished with peelings etc., covered with a wooden board for insulation from hot and cold and against drying out.

He also distinguishes this vermicompost and compost, I quote it here: "composting causes organic matter to decompose by soil microorganisms (bacteria and fungi in particular) in the presence of oxygen and water. This biological process goes through a thermophilic phase, the temperature of the core of the heap can go up to 60 ° C. After this fermentation time, a period which can exceed six months, this product, called compost, has become comparable to good quality potting soil. With vermicomposting, degradation is faster, since worms stimulate the microbial population and accelerate the transformation of organic residues. We therefore obtain a stable product after two or three months, depending on the season. There is no thermophilic phase. [...] Vermicompost is generally regarded as more fertile than compost, in particular because of the speed of transformation of the elements brought.

It remains that it is energy that dissipates. Energy that the organisms which occupy the soil under the entire cultivated surface will not have ... Now this is where you have to "work" the soil, raise it, "mix" it, feed and maintain the processes. .

I don't see the "progress" ...

[The only case that I understand is the one where, for reasons of constraints, we do not cultivate very small areas: planters, small squares ... When we have a little space, I do not understand the interest or the squares, neither composting, nor vermicompstage. The reasoning error is always the same: obsessing over the supply of nutrients to cultivated plants, instead of seeing energy questions: how to better nourish my soil organisms, so that in the end, it is they who "work" my soil better and nourish the plants better. But it is a whole vision of the mechanisms that must be changed. Otherwise, we discuss in a "vacuum"!]

Afterwards, everyone "trusts" the words or writings of whoever seems to them to be trustworthy. It's everyone's freedom.

Thank you for all these details on earthworms and their roles, as well as on the difference between compost et vermicompost...

Obviously, there are several opinions on the interest of earthworms according to their category and their actions on organic matter! It's all about balance and measurement ... and biodiversity.

I forgot an important point: Lespinasse works on squares because his land (land of Graves in the Bordeaux region) is particularly poor and his objective is to restore the fertility of his land without inputs. He also does surface composting in his squares with brf and pampers his worms at the same time. We agree, it's a big job, especially since it adds biochar, plant extracts etc.


Are the effects significant compared to these investments? Always the question I ask myself and that makes me interested in hay coverage ...

Hello,

It seems to me that organic waste, or hay, is an input.

To fertilize the land "without inputs" it would be necessary to recycle only what grows on it ...? (which is possible, thanks to solar energy)

Likewise: it is impossible for me to be affirmative! I don't have all the situations available ...

However, I also note that many "specialists", even "popes" (Bourguignon, Rabhi), do not seem sufficiently attentive to the question of the anture of the organic matters brought and especially, to the question of energy (generally occulted) ... I therefore allow myself to think on my own that they are mistaken ... I know that this is not very pretentious ... Lespinasse, I do not know precisely enough ...
