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

As one of the outreach activities during the International Decade of Soils (2015-2024) the IUSS has launched a book series.
These books are not only addressed to soil scientists, but also to academic students of other sciences. These books shall shed light on important soil issues related to other disciplines and global challenges.
The newest book is titled Soils within cities – Global approaches to their sustainable management

Viewpoints and fact sheets

In the Newsroom of this website Prof. Rattan Lal, President of the International Union of Soil Sciences regularly provides viewpoints on soil issues mainly addressed to soil science community. In addition the IUSS has started to provide fact sheets on soil in relation to issues of high importance for society. The fact sheets are written by well-known experts and are addressed not only to scientists, but also to decision makers and opinion leaders.

    IsoCycles 2017

    Conference Centre Monte Verità, Ascona, Switzerland

    The improvement of analytical techniques and the substantial increase in the number of laboratories with the instrumentation required to perform isotopic measurements have boosted the number of studies using stable isotopes.

    Stable isotopes of C, N, and S, and recently of O bound to P in phosphate, are powerful tools to trace sources, track transfers, and understand abiotic and biological processes and transformations of nutrients in the environment. However, although the biogeochemical cycles of individual nutrients are closely coupled, only a limited number of studies has attempted to combine stable isotope analyses of multiple nutrient elements.

    This combination of stable isotope analyses offers new opportunities to better understand the drivers and consequences of changes in nutrient stoichiometry across ecosystems. Advancing a coupled stable isotope research agenda in the important area of nutrient biogeochemistry is the opportunity we seek to exploit through the proposed conference.

    Submission of abstracts is open till July, 15th
