In the citing paper
“However, when the hydrochar is mixed in the soil, over a period, it becomes oxidized by interacting with atmospheric oxygen and creates a more hydrophilic nature by creating phenolic and carboxylic functional groups on the surface of the hydrochar [83].”
From Hydrochar: A Review on Its Production Technologies and Applications (2021) · cites this paper as [83]
In the citing paper
“As biochar ages, biotic and abiotic oxidation results in increased surface carboxyl groups, and subsequently increases the soils ability for cation adsorption (Cheng et al., 2008).”
From Biochar implications for sustainable agriculture and environment: A review (2019) · cites this paper as Cheng et al., 2008

“Biochar’s porous structure, large surface area, and negative surface charge (Bird et al., 2008; Cheng et al., 2008; Downie et al., 2009; Novak et al., 2009a) increase the soil’s cation exchange capacity and allow for the retention of nutrients, such as K (Liang et al., 2006; Major et al., 2011).”

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.
