  1. The numbers represent average values (n = 3 for density and n = 5 for the rest). Averages followed by the same letter in each line are not statistically different (5%) from each other according to the Kolmogorov-Smirnov test for Ca, Mg, Na, K, P and V; and according to the Tukey test for the rest. BD - Below the detection limit of the technique. 1Sum of bases (sums of the Ca, Mg, Na and K content in cmolc dm-3). 2Cation exchange capacity (sums of SB and H + Al). 3Percent base saturation (SB divided by CEC). Parameters units: Al, Ca, Mg, H + Al, P, SB, CEC (cmolc dm-3), Na, K (mg dm-3), V (%), Bulk density (g kg-1), δ13C, δ15N (‰). 4 Water filled pore space.
