Abstract

The proportions of different carbon pools within artificial soils prepared by blending composts with dolerite and basalt quarry fines has changed over a period of 7 years, accumulating inorganic carbon as carbonate minerals newly formed within the soils. With no artificial energy inputs following construction, this is regarded as a passive mineral carbonation process. Carbon isotope data show that up to 40% of the carbon within the soil carbonate is derived from photosynthesis, mixed with carbon from geological sources (limestone present in the quarry fines). Organic matter within the soils shows very variable composition, with an apparent increase with time in the relative proportion of labile carbon relative to more stable forms, reflecting a change in the soil organic matter composition associated with the establishment of new plant communities. The rate of accumulation of inorganic carbon as carbonate minerals is estimated to be equivalent to 4.8 t C ha−1 annually to a depth of 0.3 m, consistent with rates observed for accumulations of carbonate carbon in urban soils containing demolition wastes (annually 3.0 t C ha−1 to 0.3 m). There appears to be substantial potential for artificial soils to be designed expressly for the purpose of carbon capture. The process is analogous to the use of reed beds for the removal of pollutants from contaminated waters.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Similar observations have been found at other sites, where the rate of CO2 removal has been estimated on the basis of the assumption that calcium carbonate content in soil was zero at the time of demolition or soil formation.

  • Calcite precipitation has also been observed in artificial soils prepared by blending natural calcium silicate rocks with compost.

    “Although reported here for urban soils with artificial mineral inputs, calcite precipitation has also been observed in artificial soils prepared by blending natural calcium silicate rocks with compost.14”

    From Rapid Removal of Atmospheric CO2 by Urban Soils (2015) · cites this paper as [14]

  • Carbonation appears to decrease with depth, likely due to isolation of materials from the atmosphere; therefore, management that increases atmospheric exposure is likely to increase carbonation rates throughout the site.

    “Carbonation appears to decrease with depth, likely due to the isolation of materials from the atmosphere; therefore, management that increases atmospheric exposure (e.g., through appropriate planting that takes CO 2 to depth via plant root systems and associated metabolism) is likely to increase carbonation rates throughout the site.14,45,46”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
