The role of hydrology on enhanced weathering for carbon sequestration I. Modeling rock-dissolution reactions coupled to plant, soil moisture, and carbon dynamics - ScienceDirect

• A novel dynamic model connecting biogeochemical and ecohydrological dynamics to enhanced weathering is presented. • Hydrological fluctuations lead to hysteretic patterns of weathering rates with soil moisture. • Plants contribution to pH reduction and increased weathering rates during wet periods is quantified. A novel dynamic model connecting biogeochemical and ecohydrological dynamics to enhanced weathering is presented. Hydrological fluctuations lead to hysteretic patterns of weathering rates with soil moisture. Plants contribution to pH reduction and increased weathering rates during wet periods is quantified. Enhanced Weathering (EW) resulting from soil amendment with highly reactive silicate minerals is regarded as one of the most effective techniques for carbon sequestration. While in laboratory conditions silicate minerals dissolution rates are well characterized, in field conditions the rate of the dissolution reaction is more difficult to predict, not least because it
