Acid Sulfate soils cover extensive areas particularly on the tropical coasts, South-East Asia, the Caribbean and Western Africa, and they are widespread on the coasts of Australia and around the Baltic Sea. When drained, metal sulfides that have accumulated in the subsoil are gradually oxidized, giving rise to the acidification of soil and drainage waters, often with detrimental ecological consequences. If reclaimed for agriculture, these soils are commonly used for growing rice in the tropics. In temperate areas they are often drained more intensively, exposing sulfides to oxidation also in deeper horizons. These soils are impacted by change in sea level and climate events.

The 8th International Acid Sulfate Soils conference was held July 17-23, 2016 in College Park, MD. This conference provided a forum for the exchange ideas regarding the origins, properties, management, classification and reclamation of Acid Sulfate Soils.  We also included components for the education of those less familiar with Acid Sulfate Soil issues and problems (including engineers, geologists, geographers, politicians/lawmakers, environmental control organizations and agencies and the general public). Three days were designated for oral and poster presentations (July 18,19 and 21). Additionally, three field tours were planned throughout the week (July 17, 20, and 22/23).
