Table 4. Concentrations (mg kg^-1) ± standard deviation of sequentially extracted phosphorus (P) fractions and proportions of total P (P_t) in parenthesis of the control without clear-cut, 10, and 24 month after clear-cut.

Different lowercase letters indicate significant (P<0.05, n = 3) differences with time for top- or subsoil samples, respectively, whereas different uppercase letters indicate significant differences of top- and subsoil samples at the respective sampling time.
