تأثير الري بمستويات ملوحة مختلفة على إنتاجية صنفين من الشعير

أجريت التجربة في مزرعة كلية الزراعة خلال الموسم الزراعي (2003 – 2004) ف. بهدف دراسة تأثير الري بمستويات ملوحة مختلفة على إنتاجية صنفين من الشعير , فكانت مستويات ملوحة ماء الري ( 4 , 6 , 8 ) ds/m , بالإضافة إلى معاملة المقارنة 1.54 ds/m, وكانت الأصناف المختبرة هي صنفي أكساد 176 , ميمون ، كما تم الاعتماد على حسابات ملوحة التربة المتوقعة باستخدام النموذج الرياضي المقترح من Rhodes كمحاولة لتفسير النتائج بصورة علمية ومقارنتها بالنتائج الفعلية لملوحة التربة التي تعكس على الإنتاجية حيث أظهرت نتائج الحسابات تقارب قيم الملوحة المحسوبة مع القيم الفعلية عند نهاية الموسم الزراعي، كما أظهرت النتائج وجود تأثير معنوي إحصائيا لملوحة ماء الري على إنتاجية الصنفين من الحب و القش ووزن 1000 حبة (عند مستوى معنوية 5%) . حيث انخفضت الإنتاجية بزيادة ملوحة ماء الري، كما أدى الري بالمياه المالحة إلى زيادة محتوى الأوراق والسيقان من ايونات الصوديوم والبوتاسيوم والكالسيوم والماغنيسيوم والكلوريد، هذا ولم تختلف الأصناف فيما بينها معنويا (عند مستوى معنوية 5%) لكل الصفات المدروسة، كما أظهرت النتائج زيادة تدريجية لملوحة التربة بزيادة ملوحة ماء الري، بالإضافة إلى زيادة تركيز الايونات الذائبة في التربة. Abstract A field experiment was conducted in the farm of Faculty of Agriculture during the agricultural season of 2003-2004. The objective was to study the effect of different levels of salinity of water irrigation on the productivity of two varieties of barley: ACSAD 176, and Memon. The salinity levels of irrigation water were '' 4 ,6,8, '' ds/m in addition to control 1.54 ds/m.Rhodes model was used in an attempt to interpret the results scientifically , and to compare them with the actual results of soil salinity and its effect on yields .The results showed that calculated salinity values are close to those of actual salinity values at the end of the season.The results have been tested statistically on two types of seeds and straws. They showed a decrease in the yield caused by the increase of irrigation water salinity. Irrigation with salt water also led to increase of Na+, K+, mg++, CI- , Ions in leaves and stems, beside gradual increase in the salinity of soil as a result of the increase in irrigation water salinity, in addition to increase of soluble ions concentration in the soil.

Abstract This study targeted Shabiat Al-Jabal Al-Akhdhar which its area approximate (376857 Ha) and located between longitude 21َ 59ً 23.32 east to 21َ 18ً 58.28 west. Its northern border is the Mediterranean Sea and the southern border is latitude 21َ 30ً 00º. Geographical Information System (GIS) technique was applied to produce digital maps closely related to the agricultural activities. The study depended on collecting all the required data and information that achieve the goals of this study which were produced previously by various institutions. Data included the raster maps, pre-adapted databases in addition to the field survey works. All collected data were inputted into the computer with different methods the most important of was the scanner which used to input the maps of area geology, soil classification, soil salinity, soil erosion and the productive capacity of the land. Compact disks (CDs) and other methods of information transfer were used also for input into the pre-adapted databases. After input and save of all targeted data into the computer it was processed, digitalized (by Arc Map software) and these maps was converted from the raster to the digital form. Then, coding process was executed for every polygon; every character was given a specific code and separated using the specialized mapping software (Arc Map). The digital maps were produced for every one of the geological formations, microclimates, absolute levels, the slope, soil classification - at the levels of order and sub great group according to the modern American system of soil classification- soil depths, soil texture, soil salinity, stoniness and skeletal structure rates in addition to the maps of soil erosion and the productive capacity of the land. The overlay maps between the geological formations, soil formations, texture classes, microclimate and the land cover were produced too. This thesis was supported also by the maps of land cover distribution and the density of the natural vegetation cover as well as producing a map for the distribution of the service facilities of agricultural nature. These maps were prepared according to the scientific specifications as to map title, index identification and drawing scale using this technique to be easily used, saved and handled in addition to the capability to update and develop.

The Business Side of Ecosystem Services of Soil Systems

Current applications of the Ecosystems Services (ES) framework to soils are narrowly defined (e.g., soil-based, pedosphere-based, etc.), and focus on soil properties while treating soil as a closed system. Because soil is an open system, it receives and loses matter across its boundaries within Earth’s spheres (atmosphere, biosphere, hydrosphere, lithosphere, ecosphere, and anthroposphere), which also need to be accounted for in economic analysis. In market economies, the market transforms resources from the Earth’s pedosphere and related spheres into goods and services for societal welfare with non-market institutions mediating human and environmental interactions. These transformations and mediations can result not only in welfare but damages as well. The concept of soil ES and ecosystem disservices (ED) is a human-centered framework, which can be a useful tool in business decision-making. Soil ES (e.g., provisioning, regulation/ maintenance, and cultural) are used to produce goods and services, but the value of these ES and ED are not always accounted for as a part of business decision-making. The objective of this review is to illustrate the monetary valuation of ecosystem services of soil systems (SS) with examples based on the organizational hierarchy of soil systems. The organizational hierarchy of soil systems can be used in economic valuations of soil ES by scale (e.g., world, continent), time (e.g., soil, geologic), qualitative and quantitative degrees of computation (e.g., mental, verbal, descriptive, mathematical, deterministic, stochastic), and degree of complexity (e.g., mechanistic, empirical). Soil survey databases, soil analyses, Soil Data Systems (SDS), and Soil Business Systems (SBS) provide tools and a wide range of quantitative/qualitative data and information to evaluate goods and services for various business applications, but these sources of soil data may be limited in scope due to their static nature. Valuation of soil resources based on soil and non-soil science databases (e.g., National Atmospheric Deposition Program (NADP) databases, etc.) is critically needed to account for these ES/ED as part of business decision-making to provide more sustainable use of soil resources. Since most ecosystems on Earth have been modified by human activity, “soil systems goods and services” (SSGS) may be a more applicable term to describe soil contributions (benefits/damages) to economic activity, compared to a term such as “soil ecosystem goods and services.” arabic 8 English 47
