Abstract
Long-term changes in weathering rates in mineral soil horizons from the Alltcailleach Forest, north-east Scotland, were estimated from a 3-month leaching experiment conducted using archived soils sampled in 1949/50 and 1987. Data on changes in surface exchange chemistry, total element composition and mineralogy are also presented. The most sensitive Group 1 sites were characterized by a decrease in weathering rate and exchangeable Ca and Mg with time. Sodium increased in the total, exchangeable and the weatherable pools. The more base-rich Group 2 sites exhibited a slight increase in weathering rate between 1949/50 and 1987. The results have implications for the use of weathering rates in the modelling of long-term acidification of soils and water, and in the use of Na in weathering calculations as an element which is assumed not to accumulate in the soil-plant system.
