carbon soil capture - s trochou boostu. sice to jsou porad additiva a ne sustainable cesta, ale docasne to muze vytrhnout trn z paty :)
The Amazing Secret To Cutting 25% Of Carbon Could Be Under Your Feet

But what if one of the best weapons in our fight against global carbon emissions lies right beneath our feet? That’s the claim of a new generation of biotech firms, who say they can turn the world’s soil into a vast carbon sink, absorbing up to a quarter of annual emissions.

“We develop microbiological seed treatments comprised of microbial fungi and bacteria designed to provide plant benefits,” explains Guy Hudson, Soil Carbon Co. CEO. “As that plant grows it exudes sugars into the soil that are converted into stable soil carbon by the fungi.”
Once added to fields by farmers, Hudson says this solution enables the soil to quickly build significant quantities of stable carbon, stored in tiny balls of soil called microaggregates, preventing the carbon from being released back to the atmosphere.
...
“Results from our studies show a 7-17% soil carbon increase over a season. If you extrapolate out to the 1.8 billion hectares that we crop each year, you would be looking at about 8 gigatons of CO2 equivalent being drawn down,” Hudson claims. Going by IEA stats for 2019, that would equate to just under 25% of the 33 gigatons of CO2 emitted globally that year.
...
Soil carbon proponents say their solutions are comparatively easier to deploy, and relatively inexpensive: while some carbon capture methods can cost hundreds of dollars per ton of CO2 equivalent captured, Carbon Soil Co.
says its method costs between $20 and $50 per ton. What’s more, such firms are making it possible for farmers to be paid for using their soil to store carbon: one Boston start-up has claimed it wants to facilitate the storage of one trillion tons of CO2 in soil in this way, financed through a range of measures such as carbon offsets.
