EW range of basalt amendment maize 2021 mesocosms Arthur Vienne https://doi.org/10.5281/zenodo.15129984
Short summary
Our study explores Enhanced Weathering (EW) using basalt rock dust to combat climate change. We treated maize-planted mesocosms with varying basalt amounts and monitored them for 101 d. Surprisingly, we found no significant realized inorganic CO2 removal. However, rock weathering was evident through increased exchangeable bases. While inorganic CO2 removal was not realized within this experiment, basalt amendment may enhance soil health and potentially long-term carbon sequestration.
