This research was conducted in 2016c, at the Zahid Western
Research Station in Akkar Plain region of Tartous Governorate, the
objective of this research is study the effect of non-conventional
organic waste (compost of garbage, sewage sludge) and
cow
manure on the physical properties of clay soil in the region. Wastes
was added to the soil at a rate of (0 - 10 - 20 – 30) t/ha, in order to
determine the effect of the difference in the quantity added on
physical properties of the soil and peanut productivity.
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

أجريت التجارب الخاصة بهذه الدراسة في منطقتين من غوطة دمشق الأولى في منطقة أبي جرش - مزرعة كلية الزراعة والثاني في منطقة خرابو - مزرعة كلية الزراعة
الحمأة في مخلفات حيوية صلبة Biosolids سوداء اللون تنتج عن محطات معالجة مياه الصرف الصحي وتستعمل في الزراعة لما تحتويه من مواد عضوية وعناصر معدنية مغذية تزيد من خصوبة التربة وتحسن من مواصفاتها
This study was conducted during the 2011-2012 and 2012-2013 seasons in
Abu-Jarash orchards area in Damascus to identify the effect of improved
organic materials as sludge, manure and compost in improving some soil
physical characteristics and whea
t productivity. Results showed that the three
types of organic material affected the physical characteristics of the studied
soil. They decreased its bulk density, increased its total porosity and increased
its ability of holding water at field capacity. Results also showed that the
compost of city wastes was the best in improving soil physical properties. The
three organic materials, particularly the sludge increased the total productivity
of wheat (Sham3).
