Extending Maize Isotopic Evidence for Pre-contact Indigenous Agronomy to the Middle Connecticut River Valley, Connecticut, USA

Abstract

Little is known about pre-contact Indigenous agronomic practices in northeastern North America. While there is historical documentation from the early 20th century A.D. of field remnants, only a few have been subject to archaeological investigation. Recently obtained stable nitrogen isotope ratio measurements (15 N/ 14 N or δ 15 N) on charred maize (Zea mays ssp. mays) kernels have led to new insights on pre-contact Iroquoian agronomy. Here, we extend that analysis to the Burnham-Shepard and Morgan sites in Connecticut, two key late pre-contact Algonquian sites in the Connecticut River Valley. Results of δ 15 N on maize kernels recovered from these sites indicate nitrogen was not a limiting factor for maize in the sites' agricultural fields. New AMS dates on maize and other annual plant structures revise the occupational chronology of both sites. ARTICLE HISTORY

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.
