أجريت هذه الدراسة خلال عامي 2013 -2015, و قد هدفت إلى تقييم الآثار الناتجة عن تطبيق حمأة الصرف الصحي الجافة على إنتاجية الكتلة الحيوية الجافة و المخزون الخشبي في مشجر للأوكاليبتوس المنقاري تم إنشاؤه على تربة رملية في مزرعة فديو (اللاذقية) في نيسان 2013. قمنا بمقارنة أربع معاملات تجريبية عند عمر 22 شهراً و هي:SS1 (حمأة صرف صحي3 كغ/غرسة), SS2 (حمأة صرف صحي6 كغ/ غرسة), MF (سماد معدني), C (دون إضافة سماد أو حمأة). حيث بلغت إنتاجية الكتلة الحيوية الجافة فوق سطح الأرض و المخزون الخشبي في المعاملة SS1 حوالي107.60 طن/ الهكتار و 121.13 م3/ الهكتار على التوالي و معاملة السماد المعدني (87.52 طن/الهكتار و 96.98 م3/ الهكتار) و معاملة SS2(91.12 طن/الهكتار و 103.42 م3/ الهكتار), و كانت أعلى مقارنة مع معاملة الشاهد (43.89 طن/ الهكتار و 51.32 م3/ الهكتار).
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 ).

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.
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.
The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
This study dealt with the determination of hydrogen sulfide concentrations in the sediments and water of sewage points on the beach of Lattakia city - the southern Corniche region, which witnesses a clear flow of sewage water and the effect of bacter
ia on the emission of hydrogen sulfide (H2S) of high toxicity to the water medium and from it to the air and seasonal changes. These emissions and the role of hydrological factors such as salinity, acidity and temperature in this process.
This study aims to recognize some growth characteristics of
Eucalyptus camaldulensis and the effect of climate factors on trees
growth and development. Negative trends were detected in annual
rainfall according to meterological data taken from Homs station.
