Correlations between soil biochemical and soil microbiological variables showed that the three different
forest management practices had also a strong effect on soil function conditions. In a discriminate analysis,
CC and Oak were discriminated clearly, while CO was in the middle of the biplot sharing some properties
with each of the two different groups. Thus, we proposed a soil property transition from the best soil
structure and function properties at one chestnut management properties with low tree densities (CC
and CO) to other with the worst ones at highest tree density conditions (Oak). According to natural soil
conditions in Oak, we assumed that most of the enzyme activities reached their highest levels at highest
C and N soil contents but at lowest soil base saturation percentage while they were not at all associated
with P soil availability.
