7th ISCC

Background and Aims of Congress

The IUSS International Soil Classification Congress (ISCC) began in 2001 (Hungary), followed by 2004 (Russia), 2008 (Chile), 2012 (USA), 2016 (South Africa), and 2022 (Mexico). At these international congress, we have discussed the current status and problems of soil classification, observing the soil profile of agricultural, uncultivated land and urban soils.

The 7th ISCC will be held in Hokkaido, which is a representative agricultural area in Japan, and attractive as the place of pre-tour, 2day’s meeting and 3day’s excursion. We would like to discuss the various types of Andosols, dynamic soil genesis of Andosols, toposequence of soils, such as Histosols, Fluvisols, and Andosols, and impact of agriculture on soil profiles and their soil classification.

The 7th ISCC is the official conference of Commission 1.4 (Soil Classification) of the IUSS. The official classification systems of the IUSS are the World Reference Base (WRB) and USDA Soil Taxonomy. The contributions on national soil classification systems are invited and welcome. The 7th ISCC will be held in Asia for the first time, we hope you can enjoy “soil diversity” and “Omotenashi-mind” in Hokkaido, Japan. We look forward to your participation.
