Enhanced rock weathering (ERW) is increasingly considered to be a promising carbon dioxide reduction (CDR) strategy, but carbon removal can be is difficult to verify with field measurements. Reactive transport models (RTMs) have the potential to shed light on the soil dynamics affecting CDR, and to quantify the timescales involved. Here, the authors present a new 1-D RTM representing all major processes affecting the chemistry of soils. These processes include nitrogen cycling kinetics, sorption and the choice of open or closed systems with respect to gas diffusion. They demonstrate this model’s utility with a detailed investigation examining the impact of those key ERW and soil processes on CDR and topsoil pH at a site in the United States Corn Belt.
