Table 3
Absolute soil enzymatic activities (i.e. per dry soil mass) throughout profiles of undisturbed (n = 4) and disturbed (n = 9) soils. Coefficient of variation (%), for each soil layer or
genetic horizon, is reported in parenthesis. Different uppercase letters indicate significant differences (P < 0.05) between layers of disturbed soils and genetic horizons of
undisturbed soils at similar depth; lowercase letters indicate significant differences between soil layers or genetic horizons within the same soil profile.
