Eucalyptus harvest residues are attractive energy
production resources for the forestry industry. However,
their removal can have adverse impacts on soil quality and
forest productivity, especially in sandy soils. In this study,
we assessed the effects of Eucalyptus harvest residue managements
with variable intensity on forest productivity and
on physical, chemical, and biological indicators of the soil
quality. The experiment was conducted in a Quartzipsamment
(33 g kg−
1 clay) planted with Eucalyptus saligna in
Barra do Ribeiro in southern Brazil. Before the Eucalyptus
was planted, residues from the previous rotation were subjected
to five different management treatments: (1) FRM, in
which all forest residues (bark, branches, leaves, and litter)
were allowed to remain on the soil and only trunk wood was
removed; (2) FRMB, in which was identical to FRM except that bark was also removed; (3) FRMBr, in which only trunk
wood and branches were removed; (4) FRR, which involved
removing all types of residues (bark, branches, leaves, and
litter); and, (5) FRRs, in which all forest residues from the
previous rotation were removed, and leaves and branches
from the new plantation were prevented from falling onto
the soil surface using a shade net. Six years after planting,
soil samples were collected at four different depths (0–2.5,
2.5–5, 5–10, and 10–20 cm) to determine 17 soil chemical,
physical, and biological indicators. The results were
combined into a soil quality index (SQI) using the principal
component analysis approach. The SQI reduced by 30%, in
the 0–20 cm layer, due to removal of harvest residues from
the previous rotation, and collection of litter before it falls
on the ground. The main drivers of SQI reduction were the
principal components associated with soil organic matter
and biological activity. Furthermore, the SQI was positively
linearly related to tree height at P < 0.01 and to tree diameter
at breast height at P = 0.07. The adverse impact on soil quality
and forest productivity in our study indicates that removal
of Eucalyptus harvest residues from sandy soils should be
avoided. MenosEucalyptus harvest residues are attractive energy
