How biogas 1 m3 waste, at least, no

@ Did67.
No you do not speak in a vacuum, but to put it simply, I do my experiments and I see the change at ground level.
Now last year when I was told about sorghum, the general idea was that planting a sorghum seed, on arrival you had grains, and that if you left the cane, the soil would be say proportionally richer than before.
Whereas after that are carbon units of dry matter or whatever.
And that it was sorghum which always proportionally had the best yield.

Can you tell me what kind of cabbage you grow,
On the other hand I am against the GMOs of man, on the other hand those which nature makes or let us say the mutations which the plants have while adapting to their environment, do not bother me.
A specialist in this field said there is little that if we looked at the genome of the first humanoids, and those of now there is very little evolution.
And it was done in a very long time.

OKAY.

Let's take it back if you don't mind:

1) You sow your sorghum, you harvest the seeds, you incorporate the rest of the biomass.

From the point of view of mineral elements (other than carbon; therefore potassium, phosphorus, calcium, selenium, what do I know ...), your cycle is depleted exactly of the elements contained in your seeds. This is called "exports" (what goes out of the box).

From the point of view of C, the source is the CO² in the air. Indeed, the CO² captured by sorghum is only slightly exported in the seeds (it is in the starch of the grain, on which you feed, that is to say that you will finally re-decompose into CO² by extracting your energy). If you proceed as you say (you see that you have to agree: if you harvest your green sorghum to feed the cows, the deal will be quite different!) Most of it goes back to the ground. But a large part will decompose very quickly (most of it) and will be in the air again as CO². This part maintains the life of the soil in the process (all "bugs" including soil bacteria feed on it). So this has a very positive effect. But compared to your "for 1 unit, there are 7 units left", nothing to do;

Another part will turn into stable humus. A small part, but given the large biomass, this is not negligible at all.

You're right, if you do this, your soil will live (on the part of biomass that will decompose very quickly and return to the air for CO², to the soil for the other elements), it will enrich humus (the other part), will sequester CO².

The weak point of sorghum will be to exhaust the soil in N (nitrogen). After a few years, the exports of N in the vegetable proteins contained in the seeds (which are rich enough, for a cereal!) Will deplete your soil in this element.

And this is where a legume (bean, soy, alfalfa, pea, pea) would do a great job, because they are (alone) able to capture nitrogen gas from the air to incorporate it into their biomass . The share of biomass left in your plot will enrich it with nitrogen. Which is an important factor in the growth and in the efficiency of photosynthesis (nitrogen colors the leaves green, therefore photosynthesis read active, therefore more biomass produced all other things being equal) ...

I therefore strongly recommend a sorghum / legume rotation ...

I don't think that sorghum has the best yield (quantity of seeds recovered / quantity of biomass produced). I don't have the figures ... It is above all a large producer of biomass (more than corn, more than cereals; to be checked: maybe less than alfalfa).

2) Cabbage: as said, I participate in the management team, I do not manage directly. There are two varieties: one typically Alsatian sauerkraut, and a late Dutch variety ...

3) I did not want to abode the debate on GMOs. There are 50 forums on that.

I just allowed myself to note that if I had ever worked on GMOs, would everything that I have just written no longer have value [because if not, explain to me the meaning of your question?]

This way of categorizing people is unbearable to me. If you are a postman, you have no right to be crazy about Mozart and to express yourself ??? If you're a butcher, you know nothing about IT ???

In the same way, if I worked on GMOs, I would necessarily be suspect?

Bullshit for me. Excuse me for being sharp on this. The signature of a media company, where emotion dominates. It was also, before, the society of witches, that of the Inquisition ...

Re,
Good for GMOs, no worries, those who are for their reason and I respect those who are against it too. But as you say it is not the subject.

Otherwise well understood, and if by chance you find info on the biomass capacity of species, I'm interested.

Good for nitrogen, as I said earlier may not be on this subject.

I think some people call it the three sisters, I call it my thing.
But in my garden all is mixed, that is to say there is corn but sorghum but between the feet I put beans, spinach, there is of course cucumber and all the other species, I just try to manage so that the whole can have access to the sun.
An example that makes one scream with laughter or shame or what he wants.
But I have a border where there are strawberries, but I sowed a kind of old wheat and spinach in it.
After it grows I harvest if not I do with it, good for me all the predators are together and while they are at war, it takes care a little less of what I planted.
Is the performance is optimum, I don't know what is about it that I have no apparent disease, and I'm only there to watch the film of the life that goes on there.

GMO = Monsanto and the contemptuous industry laughs at the risks with herbicides and pesticides everywhere on the planet !!
Exactly as a Subprim bank = Goldman Sachs and pumping up a lot of money by creating a collection of crashes and planetary recessions !!

GMOs make drugs, but they have been misused, even we call natural flavoring on food put everywhere odors aromas made by GMO molds !!
GMO = unfortunately lies !!

In addition we allow ourselves to make GMOs too quickly, because we know almost nothing in life, like epigenetics and trash DNA (junk DNA), considered useless when it is essential (most of the genetic code) with codes in the genetic code that remain to be discovered !!!
So GMO = huge risks hidden in multicellular living beings given the unknowns to discover !!

Cancer remains a mystery of life to understand, which multiplies with our industrial junk everywhere !!

1) Nitrogen is a major element (along with phosphorus and potassium). It is a specific constituent of proteins.

So without nitrogen, no growth.

So if you export your crops, you necessarily export nitrogen ...

If you want your environment not to become impoverished, you must use legumes, in the absence of fertilizers: beans, soybeans, peas, alfalfa, clover, broad bean, faba bean ...

So it is in your interest to "promote" these plants so that your system remains sustainable.

Have you noticed that in natural meadows (it becomes rare!), There is always clover that settles ??? As soon as the grass (what is called grass!) Regresses, the clover appears and corrects the nitrogen deficiency which has weakened the cereal.

Sorghum is a cereal.

So "take care of your legumes" (in rotation or in a mixture).

3) The fact of mixing obviously makes it possible to optimize the system: better use of air space, better use of the soil (not all plants have the same root system) ...

Either you spin; it's called rotation ... So over 10 years, you finally had everything in one place ...

Either you mix ...

No importance (the mixture just opposing mechanization) ... On a small square worked by hand, no importance ...

@clasou

1) the varieties of sauerkraut are Sepdor and Mandy respectively [I don't think they are commercially available; these are selections for specialized producers - the second is Dutch]

Yield: about 70 t of cabbage per hectare (weight of cabbage, not dry matter, cabbage is mainly from the fleet!)

2) At the same time, I found the following data:

this year, in Alsace, alfalfa produced 25 tonnes of dry matter / ha in 4 cuts

a sorghum and a mixture of moha-pea-clover produced 4 tonnes of dry matter per ha (1 single cut, of course).

Thank you for the info,
Well, I'll see, I had to try alfafa (alfalfa) for a year,
To harvest the seeds that I germinate rather than to buy them.
But another species had to take over, unless I did something else instead.
good i will see.

Alfalfa is ideal in case of bio digester, you can manage the cut according to the needs of the latter, a bit like zero grazing for dairy.

Hello,
Still with the same idea, Having read a report on the brief, he spoke among other things of what he called nitrogen hunger.
Apparently following the carbon intake.
An idea that I tried but that momentarily, a vermicompostor, what would be the disadvantages advantages, of principle, say to make them digested 100 kg of straw.
Well, humidity is certainly better, I also saw that it was necessary to bring them from time to time fine sand which apparently maintains their digestive system.
And what would be good on the qualitative result of luer droppings.

Alas, no, I do not agree: the nitrogen content is too high; however nitrogen is not transformed (unlike carbohydrates, which are the basis of CH4 = methane).

It is therefore necessary to follow very closely the nitrogen content of the digester ...

[for those who know agriculture well, this is similar to the phenomenon of weathering cows]
