Table 3.

Mean values (± standard deviation) of nutritional and physical-chemical characteristics of the soil in restinga and forest. SB – sum of bases; T – potential cation exchange capacity; t – effective cation exchange capacity; m – aluminum saturation percent; V – bases saturation percent at pH 7.0. Asterisks indicate significant differences between sites (T-test, p≤0.05).
