Abstract

AGRICULTUREI, AS, B-- In the past few years, a small but growing group of researchers has been investigating preta, a rich, black soil that is believed to have sustained large settlements in Amazonia for 2 millennia. By understanding how indigenous groups created these so-called Amazonian dark earths, these researchers hope, today's scientists might be able to transform some of the region's nutrient-poor soils into new preta. Indeed, experimental programs to produce terra preta nova have already begun.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Terra preta formation has been estimated to occur in as much as 10% of the forests.

    “Terra preta formation has been estimated to occur in as much as 10% of the forests [6,7], but a prediction derived from empirical data and modelling is lacking.”

  • The overall extent to which lowland Amazonia was actively transformed into a modified landscape or cultural parkland by native people remains unknown and debated.

    “However, the overall extent to which lowland Amazonia was actively transformed into a modified landscape or cultural parkland by native people remains unknown and debated [6-10].”

  • Our estimates of potential terra preta sites were significantly less than the previous estimates of 10%.

    “Our estimates of potential terra preta sites were significantly less than the previous estimates of 10% [6,7] and did not support the assertion that most of Amazonia was a transformed landscape or cultural parkland before European arrival.”

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.
