Soil
sampling was performed before planting and after
two
vegetation periods as indicated in the soil
sampling scheme.
Similarly
as in the initial soil analyses, a high variation in the final soil extraction results
was found.
In
general, a strong decrease of soil contamination was observable, which however, also
occurs in the non-planted variants.
Dendroremediation
effects, found for growth-bioindication and time course of
soil
leaching,
could not be confirmed by soil core analyses.
Thus,
soil core analyses are not suited for (short-term!) dendroremediation control in
situ.
