Enhanced rock weathering (EW) is gaining attention as a promising carbon dioxide removal strategy, primarily due to its potential to sequester inorganic carbon through mineral dissolution. However, the broader biogeochemical implications of EW, particularly its effects on soil organic carbon (SOC) dynamics, as well as the role played by agriculturally relevant biota such as plants and earthworms, remain poorly understood. In a 15-month mesocosm experiment with Zea mays, the authors investigated how EW with basalt influences soil COâ‚‚ efflux (SCE; normalized for soil water content and temperature) and how this is modulated by plant and earthworm presence.
