Magdalena Blanz, PhD Student at the University of the Highlands and Islands Archaeology Institute, is undertaking research into seaweed as fodder, food and fertiliser in the North Atlantic Islands: past, present and future opportunities.
Magdalena attended the AEA 2018 conference, hosted by the Association for Environmental Archaeology at Moesgaard Museum, near Aarhus, Denmark from 29th November to 1st December 2018.
Magdalena’s paper was entitled “Recreating past effects of seaweed-fertilisation on the isotopic and chemical composition of barley to further palaeodietary reconstructions” for which she was awarded the prize for best student presentation at the conference.
The research concerns how fertilisation with seaweed changes the chemical and isotopic composition of the barley, and what implications this may have for reconstructing past diets. In this study, barley was fertilised with seaweed, and found an elevation in δ15N values of the seaweed-fertilised crops. This indicates that when we study δ15N values in animal and human remains, the position of the consumers of these crops in the foodchain (i.e. trophic level) may be overestimated if seaweed-fertilisation is not taken into account.
