Suppl. Table 1. Elemental concentrations in soils that were subjected to prescribed thinning, burning, or both treatments combined. Data presented are mean ± SE for n = 12. Soil samples were collected in 2008. * (P 0.05) denotes significant differences between treatments and ¶ (P 0.05) denote significant differences between B and BU or B and BO. Letters a and b denote significant differences between topsoil and subsoil (P < 0.05).
