| Sumario: | Fertilization with biosolid is an option for beneficial use of waste generated from
wastewater treatment plant. At this point of view, it is necessary know its effect
in forest plantations. The study was established in two sectors with plantations of
Eucalyptus globulus (blue gum), in the Región Metropolitana de Santiago: 1) 12 years
old plantation, without silvicultural interventions; 2) coppice 2 years old, with
multiple sprouts by stump. Were evaluated three amounts of biosolids applications: T0
(addition of 0 Mgha-1), T30 (30 Mgha-1), T50 (50 Mgha-1). In each plantation diameter
growth, predawn water potential and relative water content during four years and leaf
nutritional status of the trees during two years were measured. The main results showed
the improvement in the predawn water potential of trees fertilized with biosolids in the
12 years old plantations. The sector of coppice showed no significant differences in the
variables evaluated, as this comes from shoots of harvested stools, taking lots of root
mass which provides water and nutritional requirements for the trees. |
