Nutrient Content in Irish rainfall water

Abstract: Emissions of gases from industrial activities and even from agriculture activities and from soil as releasing of nitrogen from soils to atmosphere have been increasing steadily therefore, acid rain is the concern throughout the world. The hill field at the UCD research farm was chosen as the representative of good versatile, on which moderate to intensive farming is practised in the drier rainfall areas of Ireland. Nutrient contents in rainfall water samples were measurable, although the site of rainfall sample collection is located in the east of the country far away from the Atlantic Ocean. TDP (total dissolve phosphorus) concentrations in rainwater samples were very low. While DRP (dissolve reactive phosphorus) is the main component in some samples, the DUP (dissolve unreactive phosphorus) is dominant in others. DRP values accounted for less than 50% of dissolved phosphorus in rainfall. Sodium (Na) and Chloride (Cl) ions had the highest concentration value, because most of Irish rain originates from the Atlantic Ocean. Nitrate (NO3) had the highest value 15.2 μg·mL-1 but it associated only with mineral fertiliser spreading time. Key words: Irish rain, acid rain, nutrient content. arabic 6 English 35

Assessment of spatial and temporal variations of soil salinity using remote sensing and geographic information system in Libya

Soil salinity is one of the most important issues in arid and semi arid regions, which is directly linked to desertification and land degradation. Several studies related to soil and water salinity assessment, and mapping were conducted in Libya using traditional methods. However, they covered only the time of measurements and did not address the dynamic nature of salinity process. In addition, they lack cost and time effectiveness. Therefore, there is pressing need to use a high tech method that is cost, time and labor effective to assess the change in soil salinity in north- west of Libya. The aim of this paper is to identify the change in saline soils (Sehbkha) using Remote Sensing (RS) and geographic information system (GIS) techniques. Land Sat Satellite images data were acquired for 29 years (1972-1987-2001) to assess the pattern of change. The result revealed that there was a decrease saline soils area ( Sbehbka). Keywords: Libya, GIS, Remote Sensing, Soil, Soil Salinity, Sebkha. arabic 17 English 109

حفظ وصيانة التربة أثناء العهد الروماني بمنطقة تارسين - شمال غرب ليبيا

أجريت الدراسة لتقييم مختلف عمليات مقاومة الانجراف المائي، بمنطقة تارسين الملاصقة لمنطقة العربان من الناحية الجنوبية، و الواقعة جنوب شرق منطقة غريان، والتى تتضمنت اقامة المدرجات التعويقية الحجرية بالمجارى المائية الصغيرة وبسفوح الوديان، وإقامة المدرجات الترابية ببعض المواقع القابلة للزراعة والمتأثرة بالانجراف. بينت النتائج ايجابيات عمليات مقاومة الإنجراف المائي وحفظ التربة والمياه. إن تلك الانشاءات قد تعرضت للترسيب عبر السنين،الأمر الذي يتطلب تنظيف المدرجات بمعدل (129.88- 519.4) سنة، من أقل إلى أعلى ارتفاع لتلك المدرجات (50-200) سم، بعدد مرات تنظيف (16.4-4.16) منذ بداية اقامة المدرجات حتى عام 2020م، وأن التربة قد تتعرض للانجراف بصورة أسوأ إذا لم يتم الاهتمام بالمدرجات الحاجزة لمياه الأمطار. أظهرت الدراسة أيضاً أن تربة المنطقة تتعرض للتعرية الريحية بإزالة الغطاء النباتي الطبيعي عن طريق الرعي الجائر والاحتطاب، وعدم تعويضه بنباتات أخرى ملائمة للبيئة، الأمر الذي يوثر سلبياً على التوازن البيئي بين مكونات البيئة في منطقة الدراسة. arabic 126 English 0
