Possible Depletion in 14C in Trees Growing in Calcareous Soils
Open accessAbstract
14 C activities of decadal samples from beech trees growing under extreme calcareous conditions were compared to 14 C activities of decadal samples of the same age from a beech tree growing in a normal mold soil in order to see whether part of the carbon assimilated during photosynthesis might originate from 14 C-deficient carbonates in the soil. The calcareous soils contained from 18 to 52% calcium carbonate, and this carbonate had a mean 14 C age of 10,200 to 17,600 years BP. A comparison was also made with the 14 C activity of contemporaneous samples from Douglas Fir from the US North Pacific (Stuiver, 1982). No significant depletion in 14 C activity in beech trees growing in the highly calcareous soils was detected. The measured mean difference in 14 C activity in beech trees from calcareous and non-calcareous sites corresponds to an uptake of 0.12 ± 0.3% carbon from soil carbonates in the calcareous sites.

A general contribution of the hardwater effect has either not been observed or is very small.
“A general contribution of the so-called hardwater effect, i.e. the incorporation of carbon depleted in 14 C from water into plants through the roots, has either not been observed (Tauber 1983) or is very small (Ford et al. 2007).”

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.
