The obtained results when we apply a CCA analysis show
the narrow relation between the two groups of variables in the
chestnut coppice stand, being significant the two first canonical
variables, showing that these two whole set of data were not
independents. The structure of correlation among the variables is
different in three plots. For soil microbiological and soil biochemical
parameters, the variables dehydrogenase and K contribute more
to the first pair of canonical variates
