Economie végétale et pratiques agricoles au Bronze final et au premier âge du Fer, de la côte de l'Île-de-France à la côte de Champagne

Abstract : Late Bronze Age and Early Iron Age are for the Champagne area an expansion phase of human facilities. It is also during Late Bronze age that generalizes, at European level, adoption of new crops, millets, spelt, bitter vetch, field bean and gold of pleasure.The archaeobotanical study of 21 sites located in the plain of Troyes, the area of Reims and the Upper Seine Valley provides information on agriculture, which accompanies this expansion, and how it incorporates the changes observed in Europe. From the beginning of Late Bronze Age, diversified agriculture is in place. It includes the new plants, which take an important part in regional productions based on hulled barley, broomcorn millet, hulled wheats, including spelt and the "new" glume wheat, previously unknown in France. Lens, bitter vetch and go Id of pleasure play a significant role, complementary to that of cereals. Agriculture is stable during the 9 centuries investigated. Plots are cultivated permanently and rather intensively, without loss of soil fertility. An expansion of pasture areas is likely during early Iron Age, perhaps as fallows. Ability to produce surpluses seems low, but production systems are able to meet subsistence needs, and perpetuate. Mobilizing surplus in social practices of collective feasting is also likely. Crops show differences between geographical areas, in part related to the characteristics of the environment, but perhaps also due to some cultural affinities.
