Mean storage of N, S, exchangeable Ca, and exchangeable Mg in the uppermost 0.3-m layer under Cerrado (CE), degraded (DP) and productive (PP) pastures in January 1998. The error bars represent standard deviations (n = 3), different letters indicate significant differences according to Tukey's honest significant difference (HSD) test (P < 0.05). The S, Ca, and Mg concentrations are tenfold magnified.
