🪨❌ #EnhancedRockWeathering ist bisher keine zuverlässige Klimaschutz-Maßnahme. Es gibt zu viele Unbekannte, um die Methode sicher großflächig einzusetzen und klimarelevante Effekte zu erreichen.
Das zeigt ein Forschungsteam unter Federführung des Thünen-Instituts für #Agrarklimaschutz in einer neuen Studie.

Ann Leslie Davis: How powdered rock could help slow climate change: A method called enhanced rock weathering shows promise at capturing carbon dioxide from the air
"On a banana plantation in rural Australia, a second-generation farming family spreads crushed volcanic rock between rows of ripening fruit. Eight thousand kilometers away, two young men in central India dust the same type of rock powder onto their dry-season rice paddy, while across the ocean, a farmer in Kenya sprinkles the powder by hand onto his potato plants. Far to the north in foggy Scotland, a plot of potatoes gets the same treatment, as do cattle pastures on sunny slopes in southern Brazil.
And from Michigan to Mississippi, farmers are scattering volcanic rock dust on their wheat, soy and corn fields with ag spreaders typically reserved for dispersing crushed limestone to adjust soil acidity."

Ein Münchener Startup namens #InPlanet nutzt gemahlenes #Basaltgestein, um #Kohlendioxid zu binden und den Boden fruchtbarer zu machen. Diese Methode beschleunigt die natürliche #Verwitterung von #Gestein, was #CO2 aus der Luft in stabile Mineralien umwandelt. In Brasilien, wo das Einbringen von Gesteinsmehl in die Landwirtschaft erlaubt ist, hat InPlanet bereits 50.000 Tonnen Basalt auf 5000 Hektar verteilt.

Adding crushed volcanic rocks to agricultural fields can both improve the soil and suck down carbon dioxide. Doing so in the hot, humid tropics would be most efficient, a new study finds. Enhanced rock weathering makes use of a natural geologic process to store carbon long-term Applying 10 t

This is a fascinating article about enhanced rock weathering and carbon capture. Obviously it's not a single solution, but every part of the overall solution is important. I also appreciate that the company is supplying the basalt to farmers free of charge.

New research suggests that long-term storage of carbon from #EnhancedRockWeathering (ERW) is in the ocean, confirming our suspicion that ERW is in fact an ocean CO₂ removal (#CDR) technique.
