The effect of seaweed fertilisation on sulfur isotope ratios (δ³⁴S) and grain size in barley: Implications for agronomy and archaeological research (2024)
Journal Article
Blanz, M., Gröcke, D. R., Martin, P., & Church, M. J. (in press). The effect of seaweed fertilisation on sulfur isotope ratios (δ³⁴S) and grain size in barley: Implications for agronomy and archaeological research. Frontiers in Environmental Archaeology, 3, https://doi.org/10.3389/fearc.2024.1465082

Stable sulfur isotope ratios (δ³⁴S) in bone collagen are often employed to study the consumption of marine and freshwater fish, wetland grazing, marine foraging patterns, and the possible geographic origins of food sources. However, a recent small-sc... Read More about The effect of seaweed fertilisation on sulfur isotope ratios (δ³⁴S) and grain size in barley: Implications for agronomy and archaeological research.

Further investigation into the impact of manuring on stable carbon (δ13C) and nitrogen isotope (δ15N) values in pulses: a four-year experiment examining Celtic bean (Vicia faba) (2024)
Journal Article
Treasure, E. R., Gröcke, D. R., Lester, J. J., Bishop, R. R., Jackson, S. E., & Church, M. J. (2024). Further investigation into the impact of manuring on stable carbon (δ13C) and nitrogen isotope (δ15N) values in pulses: a four-year experiment examining Celtic bean (Vicia faba). Archaeological and Anthropological Sciences, 16(8), Article 130. https://doi.org/10.1007/s12520-024-02045-x

Plant stable carbon (δ13C) and nitrogen (δ15N) isotope values can be used to directly investigate crop husbandry practices such as manuring; a key variable in understanding the scale and intensity of past farming practices. We present new results fro...

Effects of marine biofertilisation on Celtic bean carbon, nitrogen and sulphur isotopes: implications for reconstructing past diet and farming practices (2021)
Journal Article
Gröcke, D. R., Treasure, E. R., Lester, J. J., Gron, K. J., & Church, M. J. (2021). Effects of marine biofertilisation on Celtic bean carbon, nitrogen and sulphur isotopes: implications for reconstructing past diet and farming practices. Rapid Communications in Mass Spectrometry, 35(5), Article e8985. https://doi.org/10.1002/rcm.8985

Rationale: The application of fertilisers to crops can be monitored and assessed using stable isotope ratios. However, the application of marine biofertilisers (e.g. fish, macroalgae/seaweed) on crop stable isotope ratios has been rarely studied, des...

Archaeological cereals as an isotope record of long-term soil health and anthropogenic amendment in southern Scandinavia (2021)
Journal Article
Gron, K., Larsson, M., Gröcke, D., Andersen, N., Andreasen, M., Bech, J., …Church, M. (2021). Archaeological cereals as an isotope record of long-term soil health and anthropogenic amendment in southern Scandinavia. Quaternary Science Reviews, 253, Article 106762. https://doi.org/10.1016/j.quascirev.2020.106762

Maintaining soil health is integral to agricultural production, and the archaeological record contains multiple lines of palaeoclimatic and palaeoenvironmental proxy evidence that can contribute to the understanding and analysis of long-term trajecto...

Nitrogen isotope evidence for manuring of Early Neolithic Funnel Beaker Culture cereals from Stensborg, Sweden (2017)
Journal Article
Gron, K., Gröcke, D., Larsson, M., Sørensen, L., Larsson, L., Rowley-Conwy, P., & Church, M. (2017). Nitrogen isotope evidence for manuring of Early Neolithic Funnel Beaker Culture cereals from Stensborg, Sweden. Journal of Archaeological Science: Reports, 14, 575-579. https://doi.org/10.1016/j.jasrep.2017.06.042

Little is known about arable agriculture in the Early Neolithic (4000–3300 cal BC, Funnel Beaker Culture) of Southern Scandinavia. Archaeobotanical material is rare and few archaeological sites have yielded more than a small number of charred cereal...

The influence of manuring on stable isotopes (δ13C and δ15N) in Celtic bean (Vicia faba L.): archaeobotanical and palaeodietary implications (2015)
Journal Article
Treasure, E., Church, M., & Gröcke, D. (2016). The influence of manuring on stable isotopes (δ13C and δ15N) in Celtic bean (Vicia faba L.): archaeobotanical and palaeodietary implications. Archaeological and Anthropological Sciences, 8(3), 555-562. https://doi.org/10.1007/s12520-015-0243-6

This paper examines the impact of animal manure on δ15N and δ13C values in a legume, Celtic Black broad bean (Vicia faba). In a field experiment, V. faba was cultivated in plots treated with farmyard manure and pure sheep manure. The results indicate...
