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 April - 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 ).
