أجريت التجربة في بساتين أبي جرش بدمـشق خـلال الموسـمين (2011-2012 ،2012-2013) بهدف دراسة تأثير المحسنات العضوية الآتية: حمأة، و سماد بلـدي، و كمبوسـت فـي بعـض الخـواص الفيزيائية للتربة و في إنتاجية محصول القمح. و بينت النتائج أن الأنواع الثلاثة من المحـسنات العـضوية المستخدمة قد خفضت من كثافتة التربة الظاهرية و زادت من مساميتها الكلية و من قدرتها على الاحتفـاظ بالرطوبة عند السعة الحقلية. كما تبين أن كومبوست قمامة المـدن كـان المحـسن الأفـضل للخـواص الفيزيائية للتربة من بين الأنواع المستخدمة، و أن المحسنات العضوية الثلاثـة المـضافة قـد زادت مـن الإنتاجية الكلية لمحصول القمح (شام3) المدروس مقارنة بالشاهد، و كانت حمأة الـصرف الـصحي هـي الأفضل في زيادة إنتاجية المحصول.
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 wheat 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).

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.
The study was carried out at Soil Research Center in the province of Daraa
during 2011 in order to study some physical and moisture characteristics for
cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the
Syrian Arab Rep
ublic and represents the cultivation of growing field crops
with a rainfall ranges between 150- 300 mm. The results showed that the
mechanical analysis for soil referred that its texture is clay with a good ability
to retain water, the field capacity rated between (30-38.85)%. The studied soil
has high value of available water (38.93mm) and useful water (25.69mm) in the
surface layer. The highest value of permanent wilting point and hygroscopic
moisture was reached in the final depth in studied profile soil, It was also
distinguished a high total porosity ranged between 51.78 and 55.59% with
a good air porosity amounted to 9.38 - 15.47 % in different depths and with the
decline to 5.51 % in the depth 30 - 45cm.
The effect of clay soil treatment with two levels of tobacco west compost and
organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three
replicates of each treatment on some physical properties (Aggregate size di
stribution, main
weight diameter, bulk density and porosity) and chemical properties (Organic carbon,
humic and volvic acid and humification index for big and small soil aggregates was
studied.
The results showed that tobacco west compost and organic fertilizer were effective in
increment of soil content of organic carbon, which reached (20 and 26%) for organic
fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate
soil physical properties, where The main weight diameter, stable aggregate rate and soil
porosity were increased. Whereas, bulk density decreased significantly in both treatments
compared to the control. Compost treatment affect soil physical properties more than
organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to
the control.
Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in
the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile,
volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and
3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates.
Humification index values were less than 2 in macro aggregates, while it was bigger than 2
in small aggregates.
this search has studied to know the effect of addition of three
resources (cows, sheep and poultry) and five levels (0, 7.5, 15.0,
22.5, 30.0) T/h, in some physical properties of soil, and some
characteristics of wheat, class Sham- 4. soil was sel
ected from (0-
30) cm of Ayash village in Dier AZ zour - sandy soil texture. The
experiment carried out in a pot capacity (9) kg using a (RCD) with
three replications.
This paper presents an experimental study to determine the physical and
some other important properties of certain waste materials, in order to
identify the appropriate field of their recycling. The experiments have
been carried out using five proposed materials, namely: corn cob, peanut
peel, straw, pine cone, and sticks of the stem Thistle Syrian plants.
