Soil Physics and Soil Hydrology

Welcome to the Homepage of DBG-Kommission I - Soil Physics and Soil Hydrology Typical topics of interest for this commission are the movement of water and gas in the ground, the transport of dissolved and particulate matter between the soil surface and the groundwater, the exchange of energy, water and gases between soil and atmosphere, and the measurement and characterization of hydraulic, thermal, mechanical and electromagnetic properties of soils across a variety of scales. We see ourselves as "homeland" of all people within the DBG, who are interested in this topic. These pictures visualise exemplarily some topics that are investigated by soil physics and soil hydrology. Upper left: Structure formation during dehydration of shrinking soils; Upper right: Relationship between water content in soil and water suction; Lower left: Infiltration of water into soils via preferential flow paths; Lower right: Dye pattern in soil after infiltration of stained water, serving as a tracer for water movement in the soil.

Soil Mineralogy

Our goals: Commission VII is one of eight commissions of the Deutsche Bodenkundliche Gesellschaft (German Soil Science Society) and deals with mineralogy and micromorphology of soil. Our objective is to foster quality in science, cooperation in research and scientific communication in soil mineralogy, as well as to inspire students and young scientists with interest in our field of research. For this purpose the members of commission VII are periodically organizing conferences and workshops. These meetings are often held in collaboration with other commissions or scientific associations and welcome participants from science, government, and industry. Close collaborations exist with groups working on inorganic or organic soil chemistry, soil physics and soil pollution/protection. Your contribution: All memebers of commission VII are invited to contribute to our activities by · Organizing a meeting or a workshop · Proposing a session on our annual meeting · Submitting information to our homepage · Suggesting the next chairperson for commission VII Please discuss your ideas with the current chairperson.

Soil Fertility and Plant Nutrition

The Commission IV of the German Soil Science Society (DBG) investigates the soil as a site for agricultural, horticultural and silvicultural production. Specific focus is put on matter turnover in the rooting zone interactions with groundwater and atmosphere matter turnover and balances at different scales plant availability of nutrients and water nutrient accquisition by plant roots maintenance and increase of soil fertility, incl. fertilisation To address these interdisciplinary issues, a close cooperation exists with other commissions of the DBG and with the German Society for Plant Nutrition (DGP).

The working group ”Soils in Schleswig-Holstein” that offers lectures and excursions is a platform for a common exchange of experience. Additionally symposia and information events dealing with soil topics are organized.

German Soil Assessment and Soil Evaluation

Working group German soil assessment (Bodenschätzung) and soil evaluation Soil evaluation to address a wide variety of issues is a challenging interdisciplinary task. The German soil assessment (Bodenschätzung) has a long-standing tradition as an evaluation procedure for soils suitable for agricultural use. The data collected for soil assessment purposes is of great importance and becoming ever increasingly important, as can be seen for example in the evaluation of the soil functions. The working group German soil assessment (Bodenschätzung) and soil evaluation intends to promote the exchange of experience and the discussion of results between all those involved in soil evaluation and site assessment.

Paleopedology

The German Working Group Palaeopedology (AGPP) was founded at the 16th of May 1977 in Hannover being the first working group of the Soils Science Society of Germany. Our agenda is Interdisciplinary development of paleodeology as a special discipline in soil science and geosciences and support of cooperation and exchange of information, development of specific analyses and definition of palaeopedological terms. Encouragement of interdisciplinary und regional palaeopedological research Information and discussion of palaeopedological research Introduction of young soil scientists to palaeopedological research questions Meetings are annually at different places in Middle Europe. The working group meets also during the biannual conference of the German Soil Science Society Chair: Prof. Dr. Birgit Terhorst Institut für Geographie und Geologie Julius-Maximilians-Universität Würzburg Am Hubland D-97074 Würzburg Tel.: +49 (0)931 / 888-5585 Fax: +49 (0)931 / 888-5544 Vize-Chair: Prof. Dr. Heinrich Thiemeyer Institut für Physische Geographie Johann Wolfgang Goethe-Universität Altenhöfer Allee 1 60438 Frankfurt/M.

Forest Soils

About on third of Germany is covered with forest. Hence, forest soils contribute significantly to the area of Germany. With their particular soil functions (buffering, filtering, transformation of nutrient elements and hazardous compounds) they play a crucial role in the water and nutrient turnover of landscapes. Compared to German soils which are utilized by agriculture and particularly compared to soils that are used for settlement or transportation, anthropogenic impacts on forest soils are relatively small. These soils are pivotal compartments of near-natural biotopes and ecosystems. However, human settlement in Central Europe, which started several millennia ago, has resulted in significant changes of the forest soils, which in many cases are not visible at first glance. Fire clearing, forest pasture, litter raking, charcoal and potash production, and wood harvesting carried out over centuries (the latter was often associated with changes of tree species) have left their traces. More recently, long-range effects of the industrial revolution and modern agro-industry (air pollution with sulfur, nitrogen and acids) added effects to the legacy of the past. Current endangerments for the forest soils of Germany result from climate change and particular harvesting techniques of modern forestry (intensified harvest of other biomass compartments than bolewood as substitutes of fossil fuel; highly-mechanized wood harvest).

Soil Systematics

Haplic Gleysol (Eutric) / ©M. Dworschak, Gd NRW The Working Group on Soil Systematics of the German Soil Science Society is commissioned with the further development of the german soil classification. The classification is based on two systems: - soil genetics - grouping of soil forming parent material An additional mission is to interact the results with soil scientists, geoscientific education, geoscientific authorities and the public.

Humus Forms

The Aim of Working Group Humusforms is to refine the German systematic stratifcation of humusforms. A further task is the organisation of workshops´concerning the morphological, chemical und biological properties of humusforms for students and soil surveyors. The working group is part of Commission III - Soil Biology of the German Soil Science Society. Typical Moder (pine needles, moss, lichen)

Isotopes in Soil Science

Aims of the Working Group „ Stable Isotopes in Soil Science: Exchange of experiences concerning use and analysis of stable isotopes in soil research Establish and propagate new methods and study designs in soil research Serve as a starting point for information about application and analysis potential for newcomers in isotope based research in soil ecology Advance teaching on use and analysis of stable isotopes Activities of the Working Group: Organisation of the biennial Workshop “Stable Isotopes in Soil research” (the last one in Göttingen, September 2010) Organisation of teachings and seminars, participation in teachings “Use of stable isotopes in soil process research” organised by the DBG Active participation in symposia with a focus on isotope research in the annual meeting of the DBG Administration of the Working Group: Head of the Working Group „Stable Isotopes in Soil Science“ is Prof. H. Flessa (Johann Heinrich von Thünen-Institut,I Braunschweig). He is assisted by Dr. Jens Dyckmans, lab manager of the Centre for Stable Isotope Research and Analysis (Kompetenzzentrum Stabile Isotope, KOSI)“ of the University of Göttingen. Contact History of the Working Group: The working group was founded at the 1999 annual meeting of the DBG in Hannover initiated by Fritz Beese and Heiner Flessa (then both working at the Institute of Soil Science and Forest Nutrition, University of Göttingen). The working group is part of the Commision II (Soil Chemistry).
