Hi, could you tell us how you realize this?
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.

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.

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.

It freezes physiologically from + 8°!!!
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....
