“…Pedoarchaeological research documents predictable changes in soil properties, including elemental concentrations, caused by human activities, even those occurring over a relatively short time (Barba and Ortiz, 1992;Beck, 2007;Cook and Heizer, 1965;Kern and Kämpf, 1989;Knudson et al, 2004;Middleton and Price, 1996). In particular, nutrients that are abundant in living organisms, i.e., Ca, Cu, K, Mg, Mn, N, P, Sr, and Zn, are enriched in soils and sediments from the remains of organic materials (Bowen, 1966).…”
