Effects of Sewage Sludge Application on Dry Biomass and Wood Volume of Eucalyptus Camaldulensis Plantation in Fedio (Lattakia)

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 ).

The Effect of Applying Sewage Sludge on Biomass Production and Wood Volume of Eucalyptus camaldulensis

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 pollution. 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.

Studying the growth and productivity of stone pine (Pinus pinea L.) Plantations in Daher khoraibat forest site -Snoubar Jableh – province Lattakia

The site was planted between 1960-1962 year with area size of 33 ha. The plots were systematically sampled with area size of 400 m2. The distance between plots was 100 m. Results showed that: trees number per hectare (N), stand average diameter (dbh) and height (H), basal area (G), productivity (V) and average annual growth (A.A.G) were: 237 tree/ha, 34.68 cm, 12 m, 21.91 m2/ha, 137.51 m3/ha and 2.64 m3/ha/year ; respectively. Stand height curve was developed with coefficient of determination of R2=0.50.

Estimating the wood Volume of Brutia Pine Stands (Pinus brutia Ten.) In Al- kadmous region- Tartous using satellite Images

The importance of this modern technology (remote sensing) follows from the fact that it allows estimating the wood stock by knowing the value of the NDVI index, which reduces the high cost and great effort needed by traditional forestry measurements.

Growth and Productivity of Maritime Pine and Brutia Pine at the Cool-Humid Bioclimate Zone in the Mid Altitudes of the Syrian Coastal Mountains

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. The 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.
