Poultry litter is an organic waste in Syria which can be a source of clean
energy if treated anaerobically. This research aimed to investigate the effect of
mechanical pretreatment of poultry litter in producing biogas and methane.
Experiments wer
e performed in units of fermentation laboratory on samples
ground spread over parts diameters 1 mm, 3 mm, and 10 mm at at 37°C
temperature, for a period of 42 days and compared with untreated samples
mechanically.
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 ).

This research is a continuation of previous studies on the biodiversity of the algae fuchsias to know with the aim of observing the changes that occur in the marine flora such as the emergence of new species or the disappearance of some of them in addition to studying them in terms of quantitative and biochemical terms and the changes they show according to geographical location.
