Description
Summary:The effects of acidic precipitation on agricultural and forest systems in southern Scandinavia, southwestern Scotland, southwestern Canada and northeastern U.S.A. are discussed. Nitrate and sulphate are the principal anions accounting for the hydrogen ion concentration and the nutrition benefits of these ions are considered. It is indicated that a maximum permissible level for the volume weighted annual hydrogen ion concentration of 25 ueq per litre would protect fresh waters from acidification, and, possibly, other systems.
