Compost and biochar can increase carbon sequestration by crushed rocks

Grasslands like these are located in the hilly areas of Browns Valley, California, and may be suitable for enhancing rock weathering applications to isolate atmospheric carbon. Credit: Tyler Anthony Enhanced Rock Weathering (ERW) is a proposed method of carbon dioxide sequestration, which involves spreading crushed silicate minerals into the soil to promote chemical reactions that form carbonate minerals. Essentially, the…
