Small scale camelid husbandry on the north coast of Peru (Virú Valley): Insight from stable isotope analysis (2014, methodology): “…example, wild plants (leaves) sampled from coastal sites in the Moche River Valley had d15N values as high as +17‰ (Szpak et al., 2013b), while the highest d15N value observed for unfertilized maize leaves grown under irrigation agriculture in the nearby Virú Valley was +6.4‰ (Szpak et al., 2012b).”
