The International Union of Soil Sciences (IUSS) is the global union of soil scientists. The objectives of the IUSS are to promote all branches of soil science, and to support all soil scientists across the world in the pursuit of their activities. This website provides information for IUSS members and those interested in soil science.

Internat. Decade of Soils

At the conference ‘Celebration of International Year of Soils 2015 – Achievements and Future Challenges’ IUSS President Rainer Horn proclaimed the International Decade of Soils 2015-2024!
The IDS shall be a continuation of the efforts made during the International Year of the Soils 2015. It will be marked by a number of activities on the national and international levels.

    SOMmic - Microbial Contribution and Impact on Soil Organic Matter, Structure and Genesis

    Helmholtz Centre for Environmental Research – UFZ, Leipzig, Germany

    Contents and aims:
    There is increasing evidence that microbial bio- and necromass are significant parts of SOM, interacting with soil minerals. The control of SOM forming processes via microbial activity and community dynamics in dependence on biodiversity and functional redundancy is largely unknown. Omics technologies and chemical analysis of complex mixtures, multi-isotope approaches and imaging techniques offer new research opportunities. Also latest modelling approaches, e.g. in systems ecology and environmental thermodynamics, open up new vistas to study the outlined topic. We invite presentations on recent findings, methodological challenges, and innovative concepts to the workshop and expect inspiring discussion.
    Workshop structure and invited speaker
    From Wednesday, Nov. 9, 1 pm until Friday, Nov. 11, 12 am, we will have five sessions and five keynote speakers:
    • Significant boundary conditions, micro-habitats and micro-habitat properties, processes of succession, and systems fluctuations – what can we learn from the marine microbial pump concept?
    • Who are the relevant actors and drivers and in which micro-habitats or „hot spots“ do they appear?
    • Molecular processes and components interacting with SOM and soil minerals – turnover steady state or residual `inert´ material?
    • What is the contribution of methods and modelling approaches from systems biology/ecology to understanding SOM in the soil system?
    • Modelling approaches for the integration of process components.
    Keynote speakers:
    Teri Balser, Curtin University, Perth; Markus Kleber, Oregon State University; Joshua P. Schimel, Univ. of Santa Barbara; Mary Firestone, Univ. of California, Berkeley; Claire Chenu, Centre AgroParisTech, Paris/Grignon

    Deadline for abstract submission: 31st August
