هدف هذا البحث إلى دراسة إمكانية استخدام الكاميرا الرقمية في تقدير لون التربة مع المقارنة بجدول مانسل و دراسة علاقة اللون كصفة تصنيفية هامة للتربة مع محتوى التربة من المادة العضوية و التركيب الميكانيكي و الكربونات الكلية.
This research aimed to study the possibility of using a digital camera in estimating soil color and compare it with Munsell soil color chart, and then study the correlation between soil color as important classification properties and soil content of organic matter, soil content of total carbonate and soil Texture.

The research was performed by isolating some species of soil- fungi from agricultural soils
handling with different pesticides and fungicides. Where the following fungi were isolated:
Aspergillus niger (The isolates A1 and A2), Fusarium oxysporum (
The isolate F),
Trichoderma harzianum (The isolate T). Also F. solani (The isolate F7) and T. viride (The
isolate T.v) were used, whereas they were taken from high studies laboratory- Science
Faculty- Tishreen University at a previous search.
The research was conducted to assay the ability of the previous fungi to degradation a
number of pesticides, the insecticide "Dolan", the insecticide "Plantocide", the nematicide
"Vydate" and the fungicide "Bayfidan", through the effect of double dose of each
pesticides in the biomass of the studied fungi on PDB medium. In addition to analysis the
results residues of pesticides using Spectrophotometer, and evaluation the pH values.
In order to evaluate the important role of climate on soil formation, three
different locations (Nawa, Dael and Nasib) in southern part of Syria,
representing the North West, Middle and Southern parts of Hauran Plateau
were selected and differ mai
nly in the amount of annual precipitation and
relatively with other factors. Three profiles, replicated three times, were
prepared one profile for each area.
The aim of this research is to simplify the methodof getting Evapotranspiration
Potentielle (ETP) which forms the limit of water needs for crops . This was using done
some experimental Equation like Turc formula and Thornthwaite formula
(Thornthwa
ite, 1948) compared with the modified Blaney_ Criddle formula
( BlaneyCriddle , 1950) which is considered the basic formula in this research . Also , this
research aims to find a formula enables us to use (Pans evaporation) method (class A) as a
relative evidence to the need of watering in Lattakia by comparing it with the results of
Evapotranspiration Potentielle which are calculated by the modified Blaney _Criddle
method depending on climate data from Lattakia for fifteen years (2001 – 2015) .
The results of studying the correlation coefficient and how the experimental points
spread around the linear regression curve show that Turc gave the best approximaltion
result to the developed Blaney – Criddle formula with correlation coefficient (R=0.907).
After Turc formula there is Thornthwaite formula with correlation coefficient (R=0.846) .
On the other hand Pan class A method gave approximal results to the developed Blaney–
Criddle formula with correlation coefficient (R=0.925) and with good distribution of the
experimental points around the linear regressions straight.
So, in this study experimental conditions it could beased on Turc formula and Pan
class A method as the best approximation to the developed Blaney- Criddle formula to
define the water requirement of the agriculture crops in Lattakia.
This experiment was conducted during ١٩٩٦-١٩٩٨ to ivestigate study the
effect of using different types of irrigation water on some soil properties and its
cotton, corn and wheat productivity under the agroclimatic conditions of Deir
Ezzor.
The study was carried out to comparison between of of three controlling treetments,
of soil-borne fungi in greenhouses. The treetments were as follows: An treeted control,
Formalin 3%, soil Solarization + animal manur and solarization for 50 days, and 0 , 5, 10
,15 and 20 cm depth.
