تقييم هذه الدراسة أشكال المنغنيز الكيميائية و توزعها في ترب مختارة من مختارة من محافظة حمص. استخدمت مخططات الاستخلاص التسلسلي لتجزئة المنغنيز إلى الشكل المتبادل المرتبط بالكربونات, المرتبط بأكاسيد الحديد و المنغنيز, المرتبط بالمادة العضوية, و الشكل المتبقي.
This study was undertaken to evaluate the chemical speciation and distribution of Mn in soils of Homs Governorate. Sequential extraction scheme was used to fractionate Mn into exchangeable, bound to carbonate, bound to manganese (Mn) and iron (Fe) oxide, organically bound, and residual forms.

The bacterial case of groundwater samples from Homs
Governorate was studied to determine the bacterial load,
Twenty-eight groundwater samples were collected from
various areas (including areas of the western, northern and
eastern governorates of
the governorate) between March and
July 2017. Where they were collected in sterile glass
containers after opening and running the water for 5 minutes
to avoid any external contamination.
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.
A field experiment was carried out to investigate the effects of organic
fertilizers (mushroom substrate residues, poultry manure and city compost)
and mineral fertilizers (NPK) on some properties and productivity of a
calcareous soil using chard
(Beta vulgaris) as a test crop. The plant was
cultivated at spring season 2009. The first cut was after 60 days of swing. The
results of experiment were: The NPK fertilizer significantly affected dry weight
of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was
50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50%
poultry manure gave the highest yeld compare to other treatments. However
the organic treatments did not differ significantly among them. Concentrations
of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50%
poultry manure > poultry manure > 50% NPK + 50% mushroom substrate >
mushroom substrate > 50% NPK + 50% city compost > city compost. The
organic fertilizers decreased the NPK in plant and soil compare with NPK
fertilizer treatment. However there was no significant differences between NPK
treatment yield and 50% NPK + 50 % poultry manure treatment. It was
concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry
manure) was important to get best result.
The type of tillage methods is considered to be as an important
factor for seed bed preparation, consequently, this will be reflected
in the quantity and quality of production, in comparison to control
(minimum tillage) different types of tillage
methods were used such
as turning plough, standard disk plough etc, for Anise Pimpinella
anisum seed bed preparation, the experiment was conducted in the
western area of Homs province.
This research study we adopted economic and social realities of the
two villages of Homs, village of Kattina and the village of Alkima
village and to identify the most important crops in the village and
on the animal species reared by parents.
