The fertlization of fields in Gaul (500 BCE-500 CE), approached by the biogeochemistry of cereal remains.

Résumé

The dynamic demography and economy of Gallic societies in the Second Iron Age and the Roman period is based on the efficiency of the agricultural system. One of the parameters that increased the potential of crops, and which was studied in a recently defended thesis, was the management of soil fertility. Archaeologists have often dealt with this issue from disparate sources (Latin agronomists, stall and latrine studies, offsite furniture, weed ecology), but which often only attest to the capacity to produce manure. Recent methodological developments in biogeochemistry applied to archaeobotany have made it possible to renew our knowledge of a territory that has been little studied. These isotope analyses (δ15N), applied to cereal remains from 68 archaeological sites, have shown that the use of manure was widespread throughout the northern half of France throughout the Second Iron Age and the Roman period. In some areas, it was shown that farmers used less fertiliser, probably due to geological constraints limiting agriculture. A second contribution of this study was to highlight the specific treatment of certain cereal species, in particular bare wheat, which benefited from fertilisation in a greater number of cases.
