Soil quality of first rotation Eucalyptus stands growing on an Andisol using soil microbial indicators

The potential soil biological change due to the establishment of Eucalyptus plantations in volcanic soils has not been reported. The objective of this research was to assess the soil quality of Eucalyptus stands growing on a volcanic ash derived soil, compared with a natural forest (Nat-forest, cont...
