Biological enhancement of mineral weathering by Pinus sylvestris seedlings – effects of plants, ectomycorrhizal fungi, and elevated CO₂ [PDF]

Biogeosciences, 2019
Better understanding and quantifying the relative influence of plants, associated mycorrhizal fungi, and abiotic factors such as elevated CO2 on biotic weathering is essential to constraining weathering estimates. We employed a column microcosm system to

Alive and dead earthworms capture carbon during mineral weathering through different pathways

Communications Earth & Environment
Enhanced rock weathering aims at capturing atmospheric carbon dioxide as inorganic carbon, while potentially stabilizing soil organic carbon. However, the role of soil biota in this process remains underexplored. Earthworms, being key soil engineers, may

Microbial Colonization of Bare Rocks: Laboratory Biofilm Enhances Mineral Weathering

Procedia Earth and Planetary Science, 2014
AbstractA laboratory biofilm consisting of the phototrophic cyanobacterium Nostoc punctiforme ATCC 29133 and the rock-inhabiting ascomycete Knufia petricola CBS 726.95 was tested for its mineral weathering potential. Minerals with different grain sizes and mineralogy were incubated with and without biofilm in batch and in flow-through column ...

The circular nutrient economy of terrestrial ecosystems and the consequences for rock weathering

Frontiers in Environmental Science, 2023
Earth’s biosphere is thought to exert a substantial influence on regolith evolution and chemical weathering rates. However, ecosystems are also highly efficient at retaining and recycling nutrients.

Impacts of dissolved phosphorus and soil-mineral-fluid interactions on CO2 removal through enhanced weathering of wollastonite in soils [PDF]

, 2022
International audienceThe weathering of silicate minerals removes carbon dioxide (CO2) from the atmosphere over geologic timescales and is also investigated as an engineered strategy to mitigate climate change on decadal timescales.

Design and Construction of an Experimental Setup to Enhance Mineral Weathering through the Activity of Soil Organisms

Journal of Visualized Experiments, 2023
Enhanced weathering (EW) is an emerging carbon dioxide (CO2) removal technology that can contribute to climate change mitigation. This technology relies on accelerating the natural process of mineral weathering in soils by manipulating the abiotic variables that govern this process, in particular mineral grain size and exposure to acids dissolved in ...
