dc.description.abstractThe 87Sr/86Sr ratio of a produce is generally linked with the soil geological features of the growing areas. This study aimed at assessing to which extent the addition of external Sr by agricultural practices, like irrigation and mineral nutrient supply, influences this relationship. In a first experiment, oat plants in two soils reflected the 87Sr/86Sr of the soil. However, this link was significantly altered at increasing levels of external Sr soil supplies. In a second experiment, apple trees transplanted in pots modified their original 87Sr/86Sr, which became progressively closer to the soil Sr isotope ratio. The addition of tap water and fertilizers, with different Sr isotopic signatures, slightly affected plant 87Sr/86Sr. Results confirm the potential of 87Sr/86Sr ratio as geographical tracer of agricultural commodities, but whenever the range of 87Sr/86Sr variability among soils from different geographical areas is narrow, the influence of external Sr-sources may smooth over these diversities.en_US
