Abstract

As part of efforts to reduce pressure on the Amazon and other biomes, one approach considered by Brazilian authorities and scientists is more intensive use of the soils of the interior of the northeast of the country, which are generally sandy, with low contents of organic matter and low water holding capacity and are frequently affected by severe droughts. In this work, biochars produced from waste biomasses were tested for the improvement of these soils. The highest BET (Brunauer-Emmett-Teller) specific surface areas were observed for all biochars. In the pH range studied, the water hyacinth plants (WH) sample showed the most negative zeta potentials, as well as the highest water holding capacity (WHC) values, while the zeta potentials of two quartzarenic neosol soils were consistent with their WHC values. The results suggested that despite the effect of porosity on water retention, the zeta potential could be associated with the presence of negative charges by which hydrated cationic counterions were absorbed and retained. The surface energy and its polar and dispersive components were associated with water retention, with sugar cane bagasse, orange peel, and water hyacinth biochars presenting higher SE values and larger polar components.

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

  • A high surface area, large average pore size, and high total pore volume make biochar suitable for soil amendment by capturing CO2 and other greenhouse gases, lowering soil bulk density, increasing soil moisture retention and aeration, and reducing leaching of plant nutrients from the rhizosphere.

    “The high surface area, high average pore size, and high total pore volume make biochar appropriate for soil amendment in capturing CO 2 and other GHGs, decreasing SBD, increasing soil moisture retention and aeration, and reducing leaching of plant nutrients from the rhizosphere (Wijitkosum and Jiwnok 2019; Batista et al. 2018).”

    Experimental — accuracy not yet measured

  • Biochar successfully captured CO2 through both surface adsorption and chemical reaction.

    “This is confirmed by Batista et al. (2018), noting that CO 2 was successfully captured by biochar related to both the surface adsorption and chemical reaction.”

    From Corn-cob Biochar Characterization and Application Effects to Carbon Dioxide (CO₂) Evolution in Acid Soil Added with Different Types of Fertilizers (2021) · cites this paper as Batista et al. (2018)

    The Methods section on specific surface area describes nitrogen adsorption to measure biochar properties, not CO2 capture. Results and Discussion mentions possible carbon sequestration in soil but does not say biochar captured CO2 through surface adsorption or chemical reaction. Searches for CO2 capture and those mechanisms found no supporting passage in our copy; page numbers were not available. (LLM, conf=0.77)

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.
