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.

IYS Soil message

Heavier machinery and inappropriate soil management have led to an increase in soil compaction prompting increased global concern regarding the impact of soil compaction on crop production and soil quality in mechanized agriculture. Soil compaction affects crop yields through alteration of soil physical, chemical and biological properties. Worldwide, problems from compacted soil affect an estimated 68 million hectares from farm machinery traffic alone. Research showed that approximately 80% of soil compaction from wheel traffic occurs on the first pass of a tire.

From October to December 2015 IUSS Division 4 (The Role of Soils in Sustaining Society and the Environment) will illustrate its main topics through articles written by Division 4 officers or their colleagues. These will each be highlighted every week.
This week: Commission 4.5 – History, Philosophy, and Sociology of Soil Science / Part 4
