| Integration of Turkish Soil Database into European Soil Database (5.7 MB) | The presentation outlines the major issues in updating the Turkish component of Soil Geographical Database of Eurasia which currently only contains WRB Reference Soil Group Names. Detailed information cab be found about: 1.An investigation of the development of an ESDB-based SMU/STU structure for Turkish soil data; 2.The creation of an inventory of Turkish soil data resources, in particular with reference to the SMU/STU structure; 3.Updating to the new database structure based on inputs from currently available information at ESDAC (Turkish soil data delivered for the elaboration of the Soil Atlas of Europe) and new information that needs to be retrieved from Turkish sources. | soil Geographical Database, Turkey, Soil Typological Unit | Ece Aksoy | 22-Dec-08 |
| The usefulness of isotopes in soil studies (5 MB) | The purpose of the presentation is to show the added value brought by isotopes in soil studies. After explaining what isotopes are, the differences between stable and unstable (radionuclides) isotopes and some of their properties, we will see through different research projects how useful they are to investigate salinization, nitrate leaching and water use efficiency. Fallout radionuclides (FNR) such as 137Cs have been used to assess soil erosion. Isotopes of water (18O and 2H) can be used to follow the percolation of individual precipitations or the separation of the evapotranspiration flux. Nitrogen 15 has been used to follow it infiltration through soil and the nitrogen fertilizer uptake by the plant. Three studies are presented where isotopes have been successfully used to investigate 1. A problem of salt patches in paddy fields (North-East Thailand); 2. Nitrate leaching in potato fields (Québec, Canada) and 3. Enhancing water use efficiency (Vienne, Autriche). Isotopes are high precision tools that can be used to investigate problems when associated to conventional methods of investigations. | Isotopes, soil, water, radionuclides, nitrates | Peggy Macaigne | 02-Dec-08 |
| Frontiers of Hydropedology Research and Applications - Pedologic, Architecture and Hydrologic Functions of the Earth’s Skin (15 MB) | Soil is at the critical junction of all spheres in the earth system, and water is a major driving force and transport agent in the earth’s Critical Zone (i.e., that part of the earth from the top of the vegetation down to the bottom of the aquifer, upon which nearly every life-sustaining resource and all human activities depend). Integrated studies of soil and water are imperative in order to understand, forecast, and manage natural resources and the environment to ensure human safety, human health, economic development, and sustainable development. Thus, soil and water are vital to the overall well being of society, serving as the two critical components of the Critical Zone. Soil and water contribute to the origin and evolution of life on the earth, the rise and decline of human civilizations, and the sustainability or deterioration of global ecosystems. Six of the eight Grant Environmental Challenges are directly germane to soil and water resources, i.e., land-use dynamics, hydrologic forecasting, biogeochemical cycles, climate variability, ecosystem functions, and environmentally influenced disease | Hydropedology, Critical Zone, Earth, soil | Dr. Henry LIN | 25-Nov-08 |

Karki, BinodMani Dahal | 02-Sep-08 |
| Analyse satellitaire sous système d’informations géographiques appliquée à l’érosion hydrique des sols et à d’autres risques naturels – Exemples au Liban (10 MB) | Heavy metal contamination of the environment has been and continuous to be a worldwide phenomenon that has attracted a great deal of attention from governmental and regulatory bodies. In such context, this study proposes a regression-tree model to predict the distribution and concentration level of zinc in soils of northern Lebanon under a GIS environment. Twelve terrain parameters (lithology, land cover/use, slope gradient, slope length, distance to the drainage line, proximity to roads, soil type, pH, conductivity, organic matter, stoniness ratio, and soil depth) were generated to statistically explain zinc concentration field/laboratory measurements within the study area. The built tree-model explained 88% of variance in zinc concentration selecting only ten parameters [pH (100% in relative importance), proximity to roads (80%), distance to the drainage (25%), lithology (24%), land cover/use (14%), slope gradient (10%), conductivity (7%), soil type (7%), organic matter (5%) and soil depth (5%)]. The overall accuracy of the produced quantitative zinc map (at 1:50,000 scale) was estimated to be 85%. The proposed tree model is relatively simple, and may also be applied to other areas. It is particularly useful for land-use planning and environmental decision-making. | Heavy metals; decision-tree model; soil contamination; GIS; zinc concentration; Lebanon | Rania BOU KHEIR | 10-Jun-08 |
| Soil carbon storage by digital soil mapping techniques (3.5 MB) | This presentation will discuss two methodologies in digital soil mapping: prediction of soil class and soil profile properties. An example is given in the Edgeroi Area, NSW, Australia. Current methodology for mapping soil class treats soil classes as attributes with no consideration of their taxonomic similarity. Soil classes are only treated as labels, and their prediction using data mining tools only consider minimizing the misclassification. This presentation considers utilizing the soil taxonomic distance as a criteria for prediction of soil classes. The second part of the presentation examines the use of a negative exponential profile depth function to describe the soil carbon data at different depths, and its integral to represent the carbon storage. Then we developed a method for mapping the soil profile carbon storage. | digital soil mapping, Organic Carbon, Pedometrics, Pedotransfer functions | Budiman Minasny | 09-Oct-06 |
| Self-organization of Soil Systems, Time Scales an Ecological. Significance of Pedogenic Processes (2.2 MB) | As a self-organized system, soil has its own specific structure described by a vertical pedological anisotropy resulting from the depth of action in situ of the soil-forming factors and processes of soil formation. Having a polyphase nature, each soil is a system constituting specific features in any given moment of time and space. According to the functional and structural peculiarities soil systems have their own specific spatial and temporal resolution and limitations to change. These considerations allow better understanding of the pedogenetic processes related to the ecosystem ecology. | Soil Systems, Time Scales and Ecological Significance of Pedogenic Processes | Victor Targulian | 22-Sep-06 |
