Nature – Deng et al. (2023): The environmental controls on efficiency of enhanced rock weathering in soils

Here the authors explored the impacts of coupled biogeochemical and transport processes and a set of primary environmental and operational controls, using forsterite as a proxy mineral in soils and a multiphase multi-component reactive transport model considering microbe-mediated reactions. For a onetime forsterite application of ~ 16 kg/m², complete weathering within five years can be achieved, giving an equivalent carbon removal rate of ~ 2.3 kg CO₂/m²/yr.
