Abstract

The magnitude of future climate change could be moderated by immediately reducing the amount of CO 2 entering the atmosphere as a result of energy generation and by adopting strategies that actively remove CO 2 from it. Biogeochemical improvement of soils by adding crushed, fast-reacting silicate rocks to croplands is one such CO 2-removal strategy. This approach has the potential to improve crop production, increase protection from pests and diseases, and restore soil fertility and structure. Managed croplands worldwide are already equipped for frequent rock dust additions to soils, making rapid adoption at scale feasible, and the potential benefits could generate financial incentives for widespread adoption in the agricultural sector. However, there are still obstacles to be surmounted. Audited field-scale assessments of the efficacy of CO 2 capture are urgently required together with detailed environmental monitoring. A cost-effective way to meet the rock requirements for CO 2 removal must be found, possibly involving the recycling of silicate waste materials. Finally, issues of public perception, trust and acceptance must also be addressed.

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

  • Yield enhancement from enhanced weathering is unlikely to originate directly from increases in soil carbon, but from nutrient uptake facilitated by pH effects.

    “This yield enhancement is unlikely to originate directly from increases in soil carbon, but from nutrient uptake that is facilitated by pH effects 57 .”

    From The technological and economic prospects for CO2 utilization and removal (2019) · cites this paper as [57]

    In “Crop production and protection” (page unavailable), the paper says that reversing soil acidification improves nutrient uptake and crop yields, supporting the pH-related mechanism. But “Rocks for food and soil security” says increased soil organic carbon benefits yields and that the long-term carbon effects of applying silicate rocks remain unknown. It does not establish that soil-carbon increases are unlikely to contribute directly to the yield enhancement. (LLM, conf=0.87)

  • Co-deployment of ERW with feedstock crops for BECCS and biochar could enhance the feasibility and carbon sequestration potential of these strategies.

    “Co-deployment of ERW with feedstock crops for BECCS and biochar could enhance the feasibility and carbon sequestration potential of these strategies 4,26 .”
  • Targeted amendment of agricultural soils for CO2 removal may have a role in slowing rates of soil loss by up to 45%, with the accelerated weathering of added minerals replacing inorganic nutrients and resultant formation of clays and mineral organic aggregates increasing the cation exchange capacity and water storage capacity of rebuilt soils.

    “Targeted amendment of agricultural soils for CO2 removal may have a role in slowing rates of soil loss by up to 45%, with the accelerated weathering of added minerals replacing inorganic nutrients and resultant formation of clays and mineral organic aggregates increasing the cation exchange capacity and water storage capacity of rebuilt soils 4,20 .”
  • Requirement for mining may be further reduced by utilizing artificial silicate by-products from industrial processes, including calcium-rich silicates produced by iron and steel manufacturing (slags) with a long history of agricultural usage.

    “Requirement for mining may be further reduced by utilizing artificial silicate by-products from industrial processes 37,38 , including calcium-rich silicates produced by iron and steel manufacturing (slags) with a long history of agricultural usage 4,39 .”
  • A baseline application rate of 40 t ha−1 yr−1 falls within the range of basalt amendments shown to improve crop production in field trials.

    “Using this modelling framework, we analysed a baseline application rate of 40 t ha -1 yr -1 (equivalent to a <2 mm layer of rock powder distributed on croplands), which falls within the range of basalt amendments shown to improve crop production in field trials 4 .”

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.
