Resumen:
In the present work, we have applied Mössbauer spectroscopy as well as the traditional chemical analyses to assess the contents of different states of Fe in oxides and hydroxides in an Entisol soil from the Argentine coastal plain of the Rio de La Plata. Tentative assignments for the different Fe ion sites are proposed. Our findings show that the isomer shift and quadrupole splitting are sensitive to the changes detected in the Fe2+ contents of the soluble phase while others remain constant within the experimental uncertainties.2+ contents of the soluble phase while others remain constant within the experimental uncertainties.
