Abstract The ongoing climate crisis merits an urgent need to devise management approaches and new technologies reduce atmospheric greenhouse gas concentrations (GHG) in the near term. However, each year that GHG continue rise, pressure mounts develop deploy CO 2 removal pathways as a complement to, not replacement for, emissions reductions. Soil carbon sequestration (SCS) practices working lands provide low‐tech cost‐effective means for removing from atmosphere while also delivering...
Recent analysis by the IPCC suggests that, across an array of scenarios, both GHG emissions reductions and various degrees carbon removal will be required to achieve climate stabilization at a level that avoids most dangerous changes in future. Among large number options realm natural solutions, atmospheric dioxide (CDR) via enhanced silicate weathering (EW) global working lands could, theory, billions tons CO 2 each year. Despite such potential, however, scientific verification field...
Abstract Global‐scale models of rock‐derived nutrient availability often assume that physical erosion drives soils toward an approximate “steady state” over geologic timescales. By definition, steady‐state do not represent landscape age—that is, the time elapsed since soil formation is initiated by major erosional or depositional events. We hypothesize this assumption has large consequences on estimates fertility because age can mediate retention mobile elements in soil, particularly...
Models suggest that rock-derived nitrogen (N) inputs are of global importance to ecosystem N budgets; however, field studies demonstrating the significance rock rare. We examined fluxes in soils derived from sedimentary rocks along a catena formed under semi-arid climate. Our measurements demonstrate there distinct and traceable pools soil bedrock fraction declines downslope catena. used geochemical mass balance weathering flux estimate 0.145 0.896 kg ha –1 yr at ridgecrest. also developed...
