Research summary
تناولت الدراسة تأثير إضافة كمبوست مخلفات التبغ والسماد البلدي على بعض الخصائص الفيزيائية والكيميائية للتربة الطينية. تم استخدام مستويين من الكمبوست والسماد البلدي (15 و30 طن/هكتار) بالإضافة إلى معاملة السماد المعدني، مع ثلاث مكررات لكل معاملة. أظهرت النتائج أن الكمبوست والسماد البلدي زادا من محتوى التربة من الكربون العضوي، حيث بلغت نسبة الزيادة في معاملات السماد البلدي 20% و26%، بينما بلغت في معاملات الكمبوست 39% و45% مقارنة بالشاهد. هذا التحسن في محتوى الكربون العضوي أدى إلى تحسين الخصائص الفيزيائية للتربة، مثل زيادة متوسط قطر التجمعات الموزونة وزيادة نسبة التجمعات الثابتة والمسامية، وانخفاض الكثافة الظاهرية. كما أظهرت النتائج تفوق الكمبوست على السماد البلدي في تحسين هذه الخصائص. من ناحية أخرى، أدى استخدام السماد المعدني إلى انخفاض محتوى التربة من الكربون العضوي مقارنة بالشاهد. تراوحت قيم حمض الهيوميك بين 2.12 و74.3 مغ/كغ في معاملة الشاهد ومعاملة الكمبوست (30 طن/هكتار) على التوالي في التجمعات الكبيرة (>2مم)، بينما تراوحت قيم حمض الفولفيك بين 0.93 مغ/كغ في معاملة الشاهد في التجمعات الصغيرة (<0.25مم) و3.17 مغ/كغ في معاملة السماد المعدني في التجمعات ذات القطر (0.25-2مم). كانت قيم مؤشر التنبل أقل من 2 في التجمعات الكبيرة، بينما كانت أكبر من 2 في التجمعات الصغيرة. خلصت الدراسة إلى أن استخدام كمبوست مخلفات التبغ والسماد البلدي يمكن أن يكون وسيلة فعالة لتحسين الخصائص الفيزيائية والكيميائية للتربة الطينية، ويمكن استخدامه كبديل للسماد البلدي الغالي الثمن.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين خصائص التربة الطينية باستخدام مواد طبيعية مثل كمبوست مخلفات التبغ والسماد البلدي. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين مجموعة أوسع من الترب والنباتات لاختبار فعالية الكمبوست والسماد البلدي في ظروف مختلفة. ثانياً، لم تتناول الدراسة تأثير هذه المعاملات على الإنتاجية الزراعية بشكل مفصل، وهو جانب مهم يجب مراعاته في الأبحاث المستقبلية. ثالثاً، يمكن أن تكون هناك حاجة لدراسة تأثير هذه المعاملات على المدى الطويل لضمان استدامة التحسينات في خصائص التربة. بشكل عام، توفر الدراسة قاعدة جيدة لمزيد من الأبحاث في هذا المجال، ولكن هناك حاجة لمزيد من العمل لتأكيد النتائج وتوسيع نطاقها.

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 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).
The chisel plough is the most important soil preparation machinery for planting and its direct effect on the physical properties of the soil is reflected in the cultivated yield. The purpose of this research is to evaluate the performance of the lo cal chisel plough through its positive effects on the physical properties of soil so as to tillage heavy clay soil, the most difficult types of soils, and then determine the time period for the disappearance of these effects and the return of the soil as it was prior to tillage and planting in terms of these physical properties. When planting the wheat crop under Syrian conditions. The actual field capacity of the plough was (1.01 hec/h) and field efficiency (79.53%), and consumed fuel (13.97 l/h). There was a positive change in the physical properties of the soil due to the use of the chisel plough and two perpendicular faces, where the bulk density of the soil decreased (23.8%) and moisture content from (30.85%) to (28.33%). While increasing the total soil porosity (13.26%) and air porosity (56.76% ) and void ratio (45.71%). It was found that the positive effects of the chisel disappear during one agricultural season. The process of tillage cannot be dispensed with the tillage to cultivate the wheat crop under the Syrian conditions (the Algab area). It must be done the traditional tillage (two faces), Where it was found that the soil return to its status before tillage and planting after (180) days, before the end of the planting season and before harvesting the wheat crop by about a month. It was found that some of the physical properties of the soil contributed to determining the time period for the return of the soil properties as they were prior to tillage. These include the bulk density of the soil, the total porosity of the soil and the void ratio that are directly affected by tillage. Some of the physical properties did not contribute to determining the time period for the return of soil properties as they were prior to tillage. They include both soil moisture content and air porosity, which are affected by tillage, but are more affected by climatic conditions such as temperature and rainfall.
The recent synthesis of the new polymers has been profoundly affected by the unique characteristics of Dimer Acid. These polymers were made up following the condensation with triethanolamine when was treated in melted phase. We performed identifi cation of the physical characteristics of the polymers such as the molecular weight, in addition to the acid value and hydroxyl value. Infrared spectroscopy have been used in identification of this polymer. Also, the rheological behavior has been assessed thermally and shearing stress by using capillary viscometer. Our results revealed a reduction in the viscosity with increase of the shearing stress as will as with rise in the temperature.
The main aim of this study was to determine the effect of slope position on some soil physico-chemical properties .The study was conducted on a pine forest soil , Tartous. Soil samples were collected from top , mid and bottom slope positions at hor izon- A and C of top and mid slope positions and at horizon A,(B)and C of bottom slope positions . Results showed a significant difference among the physico-chemical properties of top , mid and bottom slope soils . Bulk density of the top - slope (1.34 gcm-3) was the highest followed by mid ( 1.31 gcm-3) and bottom slopes (1.27 g cm-3) .Conversely ,Organic matter content (2.86%) ,electrical conductivity EC(0.20mmos/cm) , calcium(28.3 meq/100g) , magnesium(6.80 meq/100g) , Potassium (0.21 meq/100g), Soil pH ( 7.95) , clay content (38.43 %) and silt content (34.70%) were the highest at bottom slope followed by mid and top- slopes , respectively . Soil A and C horizon of top and mid slope positions and A ,(B)and C horizons of bottom slope positions were also significantly different in their physical and chemical properties . Horizon A had the highest organic matter ,electrical conductivity , calcium , magnesium , silt contents and lower bulk density,CaCO3, sand contents than both the (B) and C horizons of bottom slope and the C horizon of top and mid slope .The deterioration in physico-chemical properties of top slope as compared to mid and bottom slopes and that of A horizon as compared to C horizons were presumed to be due to past soil erosion effect that removed the finer soil particles including soil organic matter and other plant nutrient.
