Intensification of agriculture in southwestern Germany between the Bronze Age and Medieval period, based on archaeobotanical data from Baden-Württemberg
A system of farming with an alternation of land use between being cultivated or left fallow as grassland (Feldgraswirtschaft) developed in southwestern Germany since the Bronze Age. It involved fallow periods, where the arable land is left without crops in order to let it recover its fertility for several years while becoming grassland. This led to regeneration of the topsoil humus, which could later be mobilized by cultivation. With later farming systems, the supply of nutrients needed for crops could also be provided by manuring, which allowed shorter fallow periods but required the production of manure. Such cultivation systems with short or even without fallow phases and with intensive manuring are known from the medieval period as one, two or three field systems of agriculture and their development was an important step towards the intensification of farming. The current study considers on-site plant macrofossil data from archaeological sites as well as the off-site pollen data from cores in Baden-Württemberg in order to recognize the main changes towards agricultural intensification through time from the Bronze Age up to medieval times. The various landscape types included in the study area also reveal their different agricultural histories of intensification. In lowlands with good soils, the intensification can be recognized earlier and more strongly than in uplands or other marginal areas. The main shift towards intensification took place in the Roman period, which is also confirmed by written sources of the time that mention manuring as well as a kind of two field system and alternation between grassland and arable land.publishedVersio

Ex Oriente seges: the arrival and establishment of broomcorn millet in Europe
Cultivation of broomcorn millet (Panicum miliaceum L.) was a widespread practice in later European prehistory. When and how this ‘crop from the East’ was introduced to the continent and spread across it has not been determined. So far, based on the relative chronology of millet finds and a small set of radiocarbon-dated caryopses, it has been suggested that millet did not arrive in Europe during the Neolithic and that this happened in the Mid-Late Bronze Age. It has not been clear why and how millet was integrated into the pre-existing crop spectrum and what effect this had on the crop husbandry routine. The economic and socio-cultural contexts of the adoption of millet have not been closely examined. The 'Millet Dating Programme' recently completed at Kiel University produced 100+ radiocarbon dates on charred grains of broomcorn millet recovered from Neolithic and Bronze Age layers of sites located in different parts of Europe. Collectively, the absolute dates suggest that millet reached most of SE, central and NW Europe in the period 15-13th century BC. Using these high-precision data, we can now build a link between the start of millet cultivation and the coeval changes in subsistence economy potentially resulting from the adoption of the new crop. We present the results of this research project and discuss possible mechanisms by which millet was distributed, as well as the potential agro-ecological causes-andeffects of the establishment of millet cultivation in Europe
New AMS 14C dates track the arrival and spread of broomcorn millet cultivation and agricultural change in prehistoric Europe
Broomcorn millet (Panicum miliaceum L.) is not one of the founder crops domesticated in Southwest Asia in the early Holocene, but was domesticated in northeast China by 6000 bc. In Europe, millet was reported in Early Neolithic contexts formed by 6000 bc, but recent radiocarbon dating of a dozen 'early' grains cast doubt on these claims. Archaeobotanical evidence reveals that millet was common in Europe from the 2nd millennium bc, when major societal and economic transformations took place in the Bronze Age. We conducted an extensive programme of AMS-dating of charred broomcorn millet grains from 75 prehistoric sites in Europe. Our Bayesian model reveals that millet cultivation began in Europe at the earliest during the sixteenth century bc, and spread rapidly during the fifteenth/fourteenth centuries bc. Broomcorn millet succeeds in exceptionally wide range of growing conditions and completes its lifecycle in less than three summer months. Offering an additional harvest and thus surplus food/fodder, it likely was a transformative innovation in European prehistoric agriculture previously based mainly on (winter) cropping of wheat and barley. We provide a new, high-resolution chronological framework for this key agricultural development that likely contributed to far-reaching changes in lifestyle in late 2nd millennium bc Europe
