Resumen:
Our study area is the early agricultural archaeological site named “El Tolar” (1st to 9th century AD), located in Tafí Valley (Tucumán, Northwest Argentina). The objective of this research is to identify geochemical signatures generated by the sustained agrarian use of soils. Chemical and pedological studies were made in different archaeological contexts. Physical and chemical features, such as bulk density, pH, organic and inorganic phosphorus, and available copper, manganese and iron, were taken into account. The obtained results suggested that the buried paleosol identified was contemporary with the occupation of the site. It also showed characteristics for pre-Hispanic agrarian production. The concentrations of organic phosphorus and iron in agricultural soils reflect the probable use of fertilizers. The application of the geoscience techniques allowed us to obtain important information on their behaviour and socio-economic development. This paper constitutes the first pedo-geochemical approach to the study of Argentinean pre-Hispanic agricultural soils.
