Soil Science Society of America

The Soil Science Society of America (SSSA), is the largest soil-specific society in the United States. It was formed in 1936 from the merger of the Soils Section of the American Society of Agronomy and the American Soil Survey Association. The Soils Section of ASA became the official Americas section of the International Union of Soil Sciences in 1934, a notable role which SSSA continues to fulfill. Provided by Wikipedia
