The 7th International Acid Sulfate Soil Conference 2012
From : 26.08.2012 Till : 01.09.2012 Location : Vaasa, Finland
Acid Sulfate (AS) soils cover extensive areas, particularly on 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 accumulated in the subsoil are oxidized, giving rise to 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. Methods to use AS soils in an ecologically sustainable manner are constantly sought around the world. The conference will focus on recent advances in AS soil research, particularly in methods combating the adverse effects of these soils, which are often subject to intensive societal development. The conference offers a forum for all participants to exchange ideas also on the chemical and physical processes of these soils and, of course, classification. The earlier conferences on AS soils have been held in Wageningen, the Netherlands 1972; Bangkok, Thailand 1981; Dakar, Senegal 1986; Ho Chi Minh City, Vietnam 1992; Tweed Heads, Australia 2002; Guangzhou, China 2008. The 7th Conference will be held in the coastal city of Vaasa in western Finland in the middle of the largest AS soil area of Europe.
