This study was carried out during 2013 – 2015 and aimed to assess the effects of
applying dry sewage sludge on dry biomass production and wood volume of Eucalyptus
camaldulensis plantation established on sandy soil in Fedio plantation-Lattakia at A
pril -
2013.
Four experimental treatments were compared at age 22 months: SS1 (sewage sludge
3 kg/tree), SS2 (sewage sludge 6 kg/tree), MF (mineral fertilizer), and C (no fertilizer
applications). Aboveground dry biomass production and wood volume in the SS1
treatment were about 107.60 t/ ha and 121.13 m3/harespectively, MF treatment (87.52 t/ha,
96.98 m3/ha) and SS2 treatment (91.12 t/ha, 103.42 m3/ha)and higher than in the control
treatment (43.89 t/ha, 51.32 m3/ha ).
Generally, sewage sludge is dumped into sanitary landfills, even
though its use in forest stands as a fertilizer and soil conditioner
might be an interesting option. However, sewage sludge must be
applied with care to avoid soil and water pollutio
n. The aim of this
study was to assess the effects of applying dry sewage sludge on
wet biomass production and wood volume of short rotation
Eucalyptus camaldulensis plantation established on sandy soil in
Fedio plantation.
This research was aimed at evaluation of growth and productivity of two
pine species; namely, Maritime Pine Pinus pinaster Sol. and Brutia Pine P.
brutia Ten. at the Cool-Humid Bioclimate Zone in the Mid Altitudes of the
Coastal Mountain Ranges. T
he study revealed that, height growth was not
significant between the two species. Although average diameter at breast
height was significantly superior in Brutia pine to that of Maritime pine, this
was not reflected on productivity of trees, wood volume, or the annual growth
rate due to great differences in growth forms of the two species.
