  1. Concentrations (mg kg-1) of macronutrients (organic carbon, phosphorus, nitrogen and organic matter), micronutrients (copper, zinc, iron and manganese) and trace elements (nickel, Ni) present in soil inhabited by A. wallichiana and P. appendiculatum under field conditions. Samples from five collection sites were individually taken. Sites with lower Ni concentrations (10.25 ± 0.79 mg kg-1) were referred as ‘control site’ (CS, n = 5) and sites with higher Ni concentrations (125 ± 5.16 mg kg-1) were referred as ‘Ni-excess site’ (NS, n = 5). Data presented are means ± standard errors. Different letters (a, b) within a row indicate significant differences from each other (Tukey’s test, P ≤ 0.05).
