How biogas 1 m3 waste, at least, no

[antoinet111]

Otherwise yes it is well completed, well what is certain is that my land is much improved (alive)

Hi, could you tell us how you realize this?

[clasou]

Hello Antoine111.
For my part, my earth at the base is very clayey, suddenly when it starts to get hot, it splits. If by chance I took the spade I ended up with a block say sterile and looking at it nothing.
Now I will say that it looks a bit like forest earth, you can scratch it in your hand, you all see a bunch of beasts that before I did not see spiders and others whose names I do not know. been wet, there is a lot of plant debris, it has taken on a darker color.
And it grows wonderfully well.
To complete it's been 5 years, I think I only use an aerosol and of course no treatment (pesticide, insecticide, fertilizer) than natural species (kokopelli), any waste or plant that grows other than that that I plant are ripped from time to time and left behind, and there is also what I call my brf.
I hope I have answered your question.

Just count the number of earthworms per liter or bucket to measure the fertility of the earth with its humus !!
This is why the land with herbicides, pesticides and too much fertilizer becomes sterile at the end.

In addition read terra preta well known over 600 years ago in the Amazon with an almost sterile earth if the fine humus disappears and enriched with charcoal at the start:
http://fr.wikipedia.org/wiki/Terra_preta
how to do it:
http://jardinons.wordpress.com/2008/03/ ... -la-faire/
http://www.liberterre.fr/gaiasophia/gai ... preta.html

Terra preta is a complex mixture of "natural" soil (yellow or reddish and arid, in the case of the Amazon), charcoal, fragments of pottery objects, organic waste such as crop residues, droppings. animals and fish bones, and finally thousands of different organisms6.

Terra preta is very fertile, which is an anomaly compared to the unproductive soils of the Amazon rain forest7. Although Amazonian soils normally require fallow periods of between 8 and 10 years, six months of rest may be enough with terra preta on the ground to recover7. In at least one case, it is known that a soil of this type has been in continuous cultivation for more than 40 years without external fertilizer supply8.

Hello did67.
Yes I have by abuse of trendy language called the organic matter of brf
By cons if you can enlighten me, it is said that the plant captures the co2 of air to grow, and that is also called carbonaceous matter.
Now in your explanation, I have the impression that once digested by the soil, therefore transformed into humus, all the CO2 would have been rejected.
All or part.

1) Call it "mulch", it will be less wrong. The BRF is something precise: not too thick wood twigs (maximum thickness of the thumb roughly), crushed. It is therefore a mixture of lignin and cellulose which is still quite rich in sugars and minerals ("old wood" being very poor and very "inert", hence its use: construction, fire ... ).

This BRF will both cover the soil and prevent evaporation, regulate the temperature, shelter life, bring by its rapidly decomposable part "food" to your plants, partially humify itself (thus constitute a "reserve long duration ") and in the meantime, aerate your soil ...

So actually, what a benefit!

[the only catch is that if it were necessary to treat like this the cultivated areas in France, the forest would not be enough there; it is therefore not generalizable on a large scale; but concentrating fertility on a small patch of garden is perfect; I say it because the fanatics of the BRF sometimes get carried away a little quickly, without thinking!].

2 ° Then there, it would be necessary to make a course of biochemistry!

In very big (I will obviously be flying in the feathers!):

- plants "manufacture" their material (called organic) from CO² and water and solar energy; it always gets very, very big, organic molecules made of C and H; O of CO² and water is released as O²

- you use this organic matter in different forms:

a) you burn it: you brutally recombine C and H at high temperature with O²; you recover energy (heating for example);: you release the CO² absorbed by the plants; it is CO² neutral at the end of the cycle ...

b) you eat it: you do the same thing very gently, in the cells, at a very low temperature (37,2 ° in the morning) ... All animals do this ...

c) you anaerobic digestion: in the absence of O², certain bacteria have no choice, they break down this organic matter incompletely and combine C and H to form the smallest possible end, CH4 = methane; this molecule still contains a lot of energy, it's natural gas!

CH4 + O²: it's the famous blue flame (but you can also run motors and generate electricity) ...

d) you carbonize: you heat away from O²; H is released in the form of lots of crap including CH4; you have "naked" C left; it is coal; that you can oxidize with O² and ... recover energy ... by releasing CO²

e) you let it decompose: see b) - except that they are microorganisms

Unless the environment is not favorable (not sufficiently ventilated, too acidic): matter accumulates. It is a bog. This is also the case for "black" soils, very rich in organic matter, in eg valley bottoms with acidic soils ... or in mountains (soils that are too cold, organic matter does not decompose either) ...

This is the frame.

In a soil, the fresh organic matter that you bring will:

a) partly decompose, on the surface, aerobically (in the presence of O²); this allows all these critters to live, to proliferate; C leaves in the form of CO², the circle is complete ...

You will note in passing that a natural forest in balance is anything but "a lung"! Trees grow, die, decompose ... A forest in balance, from which nothing is extracted, is a forest that breathes as much as it rejects! And pan for the "emotional ecologists" ...

b) in part (cellulose, lignin) transform into a complex organic product, humus ...

There is between 2 and 5% humus in cultivated soil. That's tons and tons of C per ha. And it is therefore as much C which is not returned to the air in the form of CO².

c) but this humus itself decomposes very slowly, otherwise, over time, there would be only that ... So it oxidizes in the form of CO², again ...

It is therefore the biln that he is looking at: if the results are positive, the soil's humus richness rises, the soil sequesters C (therefore CO²). If it lowers, it's the opposite! However, the chemical agriculture of the last 40 years has not ceased to "plunder" the stock of soil humus ... So has enriched the atmosphere with CO²!

I think I had already touched on it, so it all comes down to following the future of C:

- oxidized, in the form of CO², it is a "waste" (energy) and a climatic poison beyond a certain content which makes the earth habitable (warming); it is also a food for plants

- when you "hide" C (build in wood - do not burn it !, peat bogs, humus in the soil, etc.), you deplete the atmosphere in CO², so you fight warming ... You sequester C ( therefore less CO²)

- when you "consume" organic matter (eat, compost, BRF, anaerobic digestion, ...) you reject the CO² that the plant has previously absorbed; So you "live" while remaining "neutral" from the CO² point of view (but recovering a lot of energy, which was originally solar energy, put in "bar" by plants). .

This is very schematically what it is.

Ok, thanks for the info,
On the other hand it will be necessary that I reread several times, because not all of them ingested.
Otherwise, good theory that ties the question a little bit to the 1 billion hungry people.
At the moment one of my hobby horses is sorghum, which I planted for the first time this year and which I will be expanding this year.
Good difficult to assess the yield because it is anarchic my garden.

But considering the ease with which it grows, if we sow it on a lot of fallow land or place that have nothing, of course with respectful ways,
Imagine the volume that we could sequester as well as the stock of grain that we could harvest.
It's a bit like when I approached hemp, all this c or co2 that we could capture and whose wool could be used to insulate, it would be as much fuel oil or other that we will save, without counting the impact on the external balance of France.

1) No. Because what are you going to do with it? Incorporate into the soil, it will especially be a rapidly decomposing material (because little cellulose) ... So everything will start off as CO² very quickly.

Sorghum is a plant of tropical origin, very sensitive to cold. It freezes physiologically from + 8 ° !!! So don't dream too much.

It is a good "food" for anaerobic digestion.

To produce biomass, in our regions, nothing exceeds alfalfa. Which in addition is not a legume that fixes nitrogen from the air. Bine more interesting. No need to "fantasize" about exotic plants.

But again, if you re-read my post above, it is biomass with rapid degradation, without much interest for the sequestration of CO². Where do you want to put this mountain of alfalfa hay or sorghum stalks ??? And if you eat or put in the ground, almost all of it is broken down into CO² (very little stable humus formed because it is too poor in cellulose and lignin).

2 ° Hemp is already in industrial production. Nothing new on the horizon. There, as we store the biomass (used as an insulator), we effectively sequester Co²!

For example, look: http: //www.eurochanvre.eu/

Several chambers of agriculture have programs in this direction.

[clasou]

Well what I had explained to me about sorghum is that schematically it took one unit of carbon for its growth and the plant was equivalent to 7 unit.

When I was talking about the fields, the idea would be one complains that people are starving, if the big one who heads decided to decide that all the fallow land, becomes say useful in the fight against hunger, and that we find a system without financial interest, we could draw a large amount of sorghum, which we can make into flour or cook like rice, never tried but info coming from a Malian friend.

Now if you say that humus level of the soil can obviously be of interest, but we can do the same thing with hemp wool which would be used to isolate the administrative buildings, therefore gain in terms of energy and co2, and the cane can always use mulch or other biomass.

here are the dreams of Sunday.

amusing:

It freezes physiologically from + 8°!!!

and it thaws at -8 ° C !!! So dream of too much !!

Otherwise bases on sorghum miracle plant, depolluting, more gluten-free good for some with problems with gluten:

Sorghum an herbaceous plant of the Poaceae family (Grasses) which bears the scientific name of Sorghum bicolor or Sorghum vulgare. It is also called big millet in Africa, Mil du Fou in Burkina Faso, Guinean corn, Indian millet or Egyptian wheat. There are several kinds of sorghum, the two main ones being grain sorghum, of which many varieties are cultivated and which is suitable for human consumption, and feed sorghum used for animal feed.
Other types of sorghum have names that determine its multiple uses: sugar sorghum, paper sorghum and broom sorghum. It has been cultivated for at least 3000 years. We find the culture of this grass 900 years before Christ, in India. We note its presence in Rome, Italy at the time of Pliny. It takes its name from the Italian "sorgo or surgo" which means "I push", but it is certainly native to Africa, and more precisely from Ethiopia, from where it spread throughout Africa.

Like cassava, sorghum contains a toxic element that turns into acid. It is therefore preferable to steam the grains before consuming them.
Its very deep root system allows it to withstand drought very well. The plant also withstands heat, drought and poor soil. Sorghum also acclimates in saline, limestone or even waterlogged soils and in temperate climates.
In Africa, it is part of the basic nutritional elements and is used in the composition of many dishes such as pancakes or donuts. In Mali, we make it a type of couscous. The plant's fibers are used to make cladding panels used in construction, biodegradable packaging or brooms. Is sorghum the plant of the future? Maybe for the Indians who will experience it as a biofuel. And maybe for everyone, if we are to believe the experience conducted in 2007 at Chanteloup-les-vignes in the Yvelines. The cereal was planted in an incultivable field because of a treatment plant. The earth was loaded with heavy metals. Sorghum feeds on copper, mercury, lead and nickel. The plant could therefore depollute the soil in depth and sorghum could become the new miracle plant. To be continued....

As far as I am concerned, this is an old black amber cane species, so the stems go up not far from 3 meters, and of which it is said that we can make molasses ?.
