The research aims to study the effect of soil content of gypsum on the Engineering Characteristics and the usability of compression. The effect of increasing the proportion of gypsum in the soil on the Atrberg limits values was studied, and found that an increase in the proportion of gypsum in the soil reduces the Plasticity. The effect of the gypsum content on the Swelling Capability for soil was studied and found that the swelling ability reduces with increasing the proportion of gypsum and the swelling pressure value also decreases with increasing the soil content of gypsum. It was studied The effect of mixing gypsum soil - cement on the usability of compression, and found that the addition of cement to the soil reduces the usability of compression.

Research summary
تهدف هذه الدراسة إلى تحليل تأثير محتوى التربة من الجبس على خصائصها الهندسية وقابليتها للانضغاط. أظهرت النتائج أن زيادة نسبة الجبس في التربة تؤدي إلى تقليل لدونتها. كما أن زيادة الرطوبة الأولية تقلل من قيمة الهبوط الانحلالي، بينما زيادة محتوى التربة من الجبس تزيد من هذه القيمة. بالإضافة إلى ذلك، كلما زادت قيمة الإجهاد المطبق، تزداد قيمة الهبوط الانحلالي للتربة الجبسية. من جهة أخرى، تقل قابلية التربة للانتفاخ وضغط الانتفاخ بزيادة محتوى التربة من الجبس. وأخيراً، تبين أن خلط التربة الجبسية بالإسمنت يقلل من قابليتها للهبوط.
Critical review
دراسة نقدية: تعتبر هذه الدراسة شاملة ومفصلة في تحليل تأثير محتوى الجبس على خصائص التربة. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تكون بحاجة إلى تحسين. أولاً، كان من الممكن تضمين المزيد من المواقع الجغرافية المختلفة لجمع العينات، مما يعزز من شمولية النتائج. ثانياً، قد يكون من المفيد استخدام تقنيات تحليلية أكثر تطوراً مثل التصوير المجهري الإلكتروني لتحليل بنية التربة بشكل أدق. وأخيراً، يمكن أن تكون الدراسة أكثر فائدة إذا تضمنت تجارب ميدانية إضافية للتحقق من النتائج المخبرية.

The reasearch was carried out during 2009 – 2010 in Al – Hasaka – Amoda - to study the effect of cattle manure at the rat of 30 ton / ha , and four organic green manure ( Lentil, Vetch, Faba bean and Barely) on soil content of organic matter and so me mineral elements compared with chemical fertilizer 400 kg / ha urea , 83 kg / ha P2O5 and 25 kg / ha K2O . The manure significantly increased organic matter , phosphorus and potassium concentrations compared with other fertilizers ( chemical and green fertilizers ) . All green fertilizers ( Lentil , Vetch , Faba bean and Barely ) significantly increased organic matter , nitrogen and potassium concentration compared with the control without using any fertilizer , the tillage depth ( 0 – 10 ) cm significantly increased soil content of organic matter and nitrogen compared with deeper tillage ( 25 – 30 ) cm during the two seasons .
This paper aims at investigating the effect of organic matter content on the engineering properties of the soil. The effect of the organic matter on both the consistency limits and strength have been investigated. The results show that the organic matter increases both the plasticity and the strength of soil. Mathematical formula is presented in which the unconfined compression strength of the soil is related to the organic matter content. It was concluded that increasing the organic matter content increases the displacement corresponding to the maximum shear stress. In addition, the effect of the organic matter has been studied and the results show that the organic matter increases the compressibility of the soil. Stabilizing the soil with cement has been investigated as well. The results show that adding the cement to the soil improves the strength of the soil and decreases its swelling potential. Depending on the organic matter content, a mathematical formula is presented to determine the required cement ratio to treat the soil to decrease its swelling potential.
This research is done in an experiment by plaster in the circumstances of Homs. The aim of this paper to study the effect of adding four different levels of phosphogypsum as much as (0.00, 6.72, 13.44, 20.16)ton / hectare (three replicates for eac h treatment) on bulk density and structure stability for clay soil has taken from (Kattina). The results showed improvement in the stability of the structure of soil specially (0.25-1)mm, increasing in aggregation degree , increasing of the rate of total porosity ,air filled porosity in comparison to the control at the two levels(13.44, 20.16)ton/hectare and also by increasing the added level . Whereas the dispersion ratio , and Bulk density were decreased when increasing the level of phosphogypsum at the same two levels. The main achieved results in this study showed , a significant increase in aggregation degree in the soil when increasing the ratio of the added phosphogypsum at the levels( 6.72, 13.44, 20.16) in comparasion with control . In other way the dispersion ratio was decreased and had negative relationship when increasing the level of the added phosphogypsum in comparasion with control .
A research was carried out at Al-Sanouber research station in Lattakia in 2013/2014 season ,The research included six treatments with four replicates for each treatment. Six treatments used of OMWW (0 , 10 , 20 , 30 , 40 , 50) l/m2. The OMWW has b een added 40 days before planting. Samples of soil have been taken before adding OMWW, then after one and two months from planting, and at the end of the season in order to make some physical and chemical analysis and also to know the concentration of some micro elements .
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.
