“…Concentrations of Olsen P, N-NO 3 and exchangeable Ca were much lower than those characterizing agricultural soils (Barker and Bryson, 2007;Morari et al, 2008) and, generally, lower than the concentrations in soils developed on waste produced by the coal industry (Dutta and Agrawal, 2001;Juwarkar and Jambhulkar, 2008;Woch et al, 2013) or in soils affected by metal ore mining and smelting (Álvarez et al, 2003;Lorenc-Pluci nska et al, 2013;Stefanowicz et al, 2012). Only amounts of exchangeable K and N-NH 4 were similar, or higher, compared with the values recorded for soils of other industrial sites Dutta and Agrawal, 2001;LorencPluci nska et al, 2013;Mummey et al, 2002;Stefanowicz et al, 2012;Woch et al, 2013).…”
