4 per thousand, store carbon in global soils

[Moindreffor]

I give a lead. Are you paranoid or what? Molluscs transform Co2 into calcium carbonate (limestone) ...
You just have to see what it has given over millions of years... mountains, massifs, islands, etc ...

that's exactly why your idea, based on a reality is a bad idea, since we no longer have millions of years in front of us
between there is urgency and over millions of years there is like an incongruity

Uh ... have you seen the billions of tons of limestone spread across the globe ??? The mountain ranges, the islands? Look at the weight of an oyster and conclude what you like. I still believe this is a good solution.
Phytoplankton alone captures more than half of the terrestrial CO2!

I think that you have an apriori when you answer us, I did say that your idea was founded, except that the phenomena that you evoke took place as you say it over millions of years and as you add it with billion tons, so how could we compress the equivalent of over millions of years of production in 50 years and on a human scale produce billions of tons of oysters?

In 2010, world shellfish farming produced 14.2 million tons, it would therefore be necessary to multiply world production by 1000 to reach 14.2 billion tons therefore for 7 billion inhabitants, a consumption of one ton per person

otherwise produce, at a loss, that is to say produce and euthanize to deposit the shells at the bottom of the oceans or elsewhere

Everything is good to take to capture and fix the carbon. Unfortunately, there is no silver bullet.

you can see it like that ... but it's a bit like the last straw in the ocean
the solution is not in the capture of CO₂ but as always the best waste is the one that is not produced, so the solution lies in reducing the production of CO₂ except that it is not on the agenda, as long as we do not change the paradigm, climate change has a bright future ahead of it

Ps: Izy ... your "document" comes from the ministry. To compare forests and agriculture to explain that the existence of the first compensates for the exercise of the second, it was necessary to dare. Are you really gobbling? Not if ?

It is not false...
At the same time, carbon storage in soils is not counted in their outdated calculations. https://www.statistiques.developpement- ... es-liees-a, while ...

Under certain conditions, the soil can store more
that it does not emit. There is, in total, more carbon in the
soil than in the vegetation that covers it and
atmosphere combined, since it is a minimum
estimated at 1 billion tonnes of carbon in
organic matter in global soils, more than
twice the carbon of atmospheric CO2. https://agriculture.gouv.fr/stockage-du ... imentation

Finally something concrete for agriculture
Storing carbon means restoring organic matter https://www.terre-net.fr/observatoire-t ... 04012.html

The assessment of additional carbon storage involves models

"MY SOILS GAIN 0,2% OF OM PER YEAR"

Carbon neutrality without sacrificing yields: this is the goal of this farmer from the United Kingdom, who relies on biostimulants and cutlery to keep his soils in full health.

Parton grows milling wheat, winter rapeseed, malting barley, lupines and grass. The latter is an essential part of the rotation. It supplies haylage which he sells to horse owners. “Grass is great for sequestering carbon and improving the soil. »On a three-year rotation, 49 hectares are left in grass and 4 hectares are in permanent pasture.

Another aspect is the place given to the cutlery. “The more diversity there is on the surface, the more there is underground. In the end, for me it is about trying to fix as much carbon as possible. »The choice of intermediate crops meets specific objectives. "To decompact the soil? Improve your health? Prepare the biological medium for the next culture? It is by asking these questions that we can identify plants capable of fulfilling a specific mission. He introduced a great diversity of plant cover: vetch, beans, rye, oats, radish, buckwheat, phacelia, quinoa, sunflowers, kale, white and purple clovers and Alexandrian clovers.

A key element of its production method is the consistent use of microbiological products. “I had never heard of nitrogen fixing bacteria before I started using them in 2012. Everywhere I inoculated them I got 1 extra ton of wheat per hectare and reduced the amount of nitrogen by 40 kg per hectare. "

Biostimulants
Biostimulants are naturally occurring microbial strains derived from organic matter and microorganisms, which can be applied to plants to supplement soil biology, improve nutrient uptake, and control pests, diseases and weeds. They can also help restore soil health, improve water retention, and maintain soil microbial levels.

When he assessed the farm's carbon footprint using the “Farm Carbon Toolkit” - a tool allowing farmers to measure, understand and act on their greenhouse gas emissions and improve resilience of their activity - the results showed an excellent balance sheet, with a total of 10 tonnes of carbon in its soils.

By changing its farming methods, the cost of producing wheat has dropped from £ 120 (€ 140) per tonne 10 years ago to £ 55-65 (€ 64- 76) per tonne today, and the machine wear has also been reduced ...

At 52 min she talks about root exudates which allow the association of carbon molecules with a clay particle, storing it for a long time. Carbon fixation is 2.5 times higher from the roots than from the mulch if I understood correctly. There was no question of the carbon / clay ratio dear to Pascal Boivin

"Regeneration Mission": a documentary on the power of soils to reverse the curve of global warming

It's a simple idea, but with great potential. Regenerating the soil to better capture CO2 is the solution presented by the documentary "Mission Regeneration", which was released in theaters on Wednesday 9 November. In the midst of COP27, he recalls that all solutions must be implemented together to reverse the curve of global warming. A resolutely positive film that explains the impact of agriculture on climate change and presents numerous initiatives all over the world.

"In 2013, we were about to have a child, and as lifelong environmentalists, we had serious fears about what the future world might hold for our unborn child," the couple share. film directors, Josh and Rebecca Tickell. It was then that they heard about the "power of the soil to reduce the carbon that humanity emits into the atmosphere", a subject carried by a community of scientists, NGOs and committed farmers, which is at the heart of their documentary. "Mission Regeneration", released in theaters on November 9, in the middle of COP27.

The first part of the film is a real kickstarter, showing the impasse in which the world food system is engaged. From plowing, which releases the CO2 buried in the soil, to pesticides, which destroy precious ecosystems to store carbon, through the desertification which threatens many areas of the world, the excesses of industrial agriculture are scrutinized. But solutions exist, and it is on this point that the documentary insists.
Regenerative agriculture vs agroecology

Thus, during the COP21 in 2015, the Minister of Agriculture Stéphane Le Foll supported the 4 per 1000 initiative, which aims to encourage the sequestration of carbon in the soil by agriculture. "This international research program makes it possible to reconcile the objectives of food security and the fight against global warming" explained the Minister. From China to Zimbabwe via the United States and France, many experiences of working the land to restore ecosystems have proven their worth.

The documentary follows the lives of several people committed to developing agriculture that respects the soil, such as Ray Archuleta, an agronomist who has made it his mission to train American farmers or Gabe Brown, a farmer who has bet on the diversification of its production after experiencing several years of crop destruction due to droughts and storms.

Regenerative agriculture is close to agroecology, but it is this second term that the IPES Food "Smoke and mirrors" report favors, warning of the risks of ambiguity. According to this panel of independent experts, agroecology benefits from a greater number of scientific researches. It also takes into account the dimensions of governance and social justice. Regeneration, however, remains a more precise term than that of "nature-based solutions", which could mask ultimately conventional practices.

In reality, man will as always favor his comfort and the production of energy with biomass, rather than the storage of carbon in the soil, which is destined to remain marginal.

In any case, it's off to a good start with the take-off of biofuels, biogas, wood energy, generalization of peeling stoves...

[izentrop]

Beware of the excesses of "regenerative agriculture" which made me think of this...

Regenerative Agriculture, what is it in reality?

The theoretical conceptual synthesis of AB and ACS is the now very noisy Agriculture Régénérative Bio = "Organic Regenerative Agriculture", supported by IFOAM, Regeneration International, Kiss the Ground, SaveSoil, Conscious Planet, Pour une Agriculture du Living, and an impressive and growing number of NGOs and institutions which all have in common that they communicate their "story telling" a lot (the communicators speak of "narration") to the general public, media, politicians, institutions, and to be remunerate for their media, ideological and political influence, whether by government institutions, large private agri-food groups, billionaires or "green" financiers, without however providing the least practical technical solution to farmers.

In summary, Regenerative Agriculture, like Agroecology in its time, is Organic, adorned with the attributes of ACS.

Whether it is Rudolf Steiner, Miguel Altieri or Sadhguru, the background is the same, political, ideological, quasi-religious. And a blatant denial of reality for those who know the terrain, the technique, and Nature...

It is as dangerous as the sectarian phenomenon that all "magical thinking" is in reality, close to Biodynamics, Anthroposophy, New Age, etc.

Nature does not forgive the fragile who deviate from material reality...

INRA has carried out ACS trials without herbicide in Grignon and Versailles. Wheat crops were invaded by undestroyed cover crops and weeds. Maize only passed the first stages for a third of the plants, as the undestroyed cover competed with it. It was perfectly predictable by any farmer or agronomist.

What should warn us is the dramatic case of the conversion of Sri Lanka by the influence of a few people from the organizations mentioned above, on a dictator president "converted" overnight to Organic Agriculture (called Regenerative), forcing all farmers to do without fertilizers and chemicals, reducing food production and the export of tea (a source of currency) to almost nothing in a few months...
