Comparison among habitat types (C = center, FE = forest edge, P = pine plots) with regard to soil concentrations of macro- and micronutrients obtained from soil samples from plots. Values are expressed as ±1 SE. Means sharing the same letter do not differ significantly according to𝛼=0.05 to Tukey’s HSD.
