Pascal Boivin explains in this conference that this rate also depends on the amount of clay in the soil and has been increasing in Switzerland since the 2000s and that the target has even been exceeded since 2012.
Largely above the following years

In France we must be in the same progression, since the directive CIPAN is European.


Unfortunately, without help and with a public opinion that wants organic and remove a herbicide that facilitates conservation agriculture, the trend is likely to reverse in the coming years.

And there you have it ... pure green bashing and pro industrial lobbying. Can't help yourself, can you? It's stronger than you ... Too bad.

You draw faster than your shadow.
Organic, because of the tillage much used to fight against weeds. Pascal Boivin also says this in the video and we can clearly see that they are generally poorly placed to store carbon in the soil.

Rare are those who make organic in ACS, the climate must be suitable.

We look forward to seeing you!
Small table corner calculation:
He says that in Switzerland, between 2006 and 2020, agricultural land stored 1% of carbon in 20 cm of soil, this corresponds to 2000 cubic meters / hectare
Suddenly with 1kg per m250 of soil weight. If we take + 3% of C stored over 1 years, that makes 14 kg per m12,5 of soil, 3T of carbon per ha. When we add the 25 oxygen atoms, this represents an equivalent of 2T of CO90 stored per hectare.
The French UAA represents around 29 million hectares https://fr.wikipedia.org/wiki/Surface_agricole_utilisée.
In the video, even permanent grasslands are counted, taking the same basis:
90 X 29/14 X 10e12 = Unless I'm mistaken, in France, an average of 186.4 Gt of CO2 stored per year.

Avalis writes:
a hectare of wheat or corn captures 4 to 8 times more CO2 than it is emitted to produce it.

At harvest, this process made it possible to manufacture 15 to 20 tonnes of biomass per hectare (50% in the form of grains, 50% in the form of straw and roots).

After harvesting, the straws that are incorporated into the soil decompose into humus, a guarantee of soil fertility and a carbon reservoir.

For example, 7,5 to 10 tons of straw and roots produce 1,1 to 1,5 tons of stable humus in the soil. This represents a stock of 450 to 600 kg of carbon, or 1 to 650 kg eq CO2 per hectare. We thus speak of “carbon sinks”.

Guy does honor to your signature and finds a real way to store the carbon instead of being in the positive or negative criticism, but sterile, in addition Elon Musk offers 100 million dollars to the key : Mrgreen:
that should motivate you right?

It dates from 2015, I think there is a good chance that he is at the origin of the initiative.
On a world scale, stocks trapped by soil and biomass weigh 2 billion tonnes, or two to three more than the mass of atmospheric carbon. A figure to be compared to the 400 billion tonnes emitted per year by human activities. So if we could increase the storage of organic carbon to four per thousand (2) on a world scale, humanity could cancel its emissions.

If you want to fix carbon ad vitam æternam, make shellfish, mussel, oyster, snail. It is thanks to them that the atmosphere has become breathable ... biomass is good, but it ends up releasing everything.
