Abstract

Soils Vary in terms of the characteristics,properties and composition. So, the research has taken the study of physical and chemical properties of soils with analysis, highlighting the spatial relationships of these characteristics in Al-Mansuriyya district ( Delly Abbas ) which is located 95 km northeast of Baghdad in Diyala province, and mediates between theDiyala River and the Khalis Channel about an area ( 331969 ) acres . It turns out that the study area is a sediment modern dating back to the Quaternary and it is a part of the of alluvial plain deposits ,its surface heights range in between ( 44-175 m) above sea level , while the laboratory analysis and field observations to describe morphological phenomena, physical and chemical properties of the soils in the study area, included on the bulk density values that varied spatially in the study area and the three depths ranged between ( 1.26 -1.78 ) g / cm 3 in the first zone of Sherwin section X the Northern of MountainMansurriyya, and the real density values ranged between( 2.47 -2.71 ) g / cm 3 in the first area of Sherwin and section VI the MountainMansurriyya for the three depths, and the values of porosity vary in the soil of the study area from one place to another , and even at the one- level depth, and ranged according to the three depths between ( 31.80 % - 51.91 % ) in the tenth section in the area of MountainMansurriyya and theeight section of the Northern MountainMansurriyya, and the proportion of salt range between( 0.93 -17.24 ) Desmenz / m in the sixth section of the Mountain Mansurriyya and the ninth section for Altjiddari , and it was according to the American classification of salinity(S3-S0) , while the organic object in the study area is generally suffering from a lack of organic object and varied spatially in the sections of the study area and ranged by depths between ( 0.24 % - 2.66 %) in the fourth section in Shohani and the ninth section for AltjiddariIn order to achieve the geographical objectives in distribution of soils in the study area , depending on the classification of Iraq for the year 1975 for production ability , soils has classified in the study area within the first five classes .

تتباين الترب من حيث خصائصها وصفاتها وتكوينها ومن هذا المنطلق فقد تناول البحث دراسة الخصائص الفيزيائية والكيميائية للترب وتحليلها وإبراز العلاقات المكانية لهذه الخصائص في ناحية المنصورية (دلي عباس) التي تقع على بعد (95)كم شمال شرق بغداد في قضاء الخالص وتتوسط مابين نهر ديالى وقناة الخالص وبمساحة(331969)دونماً.وتبين انمنطقة الدراسة هي عبارة عن ترسبات حديثة تعود الى العصر الرباعي وهي جزء من ترسبات السهل الرسوبي , وتتراوح ارتفاعات سطحها بين (42- 175)م فوق مستوى سطح البحر , اما التحليلات المختبرية والمشاهدات الحقلية في وصف الظواهر المورفولوجية والخصائص الفيزيائية والكيميائية لترب منطقة الدراسة فقد شملت الكثافة الظاهرية التي تباينت قيمها مكانياً في مقاطع منطقة الدراسةوللأعماق الثلاثة وتراوحت بين (1,26- 1,78) غرام/سم3 في المقطع الاول منطقة شروين والمقطع العاشر منصورية الجبل الشمالي, وتراوحت قيم الكثافة الحقيقية بين (2,47-
