  • a Measurements at D0 were performed on the initial homogenized soil partitioned into 4 subsamples.

  • b Asterisks indicate significant differences at the 0.05 (*) or 0.01 (**) level between D0 and the subsequent time points within each transplantation set, calculated with the Tukey test for pairwise comparisons. NA, not available.
