Sulphate leaching from diffuse agricultural and forest sources in a large central European catchment during 1900-2010

Popis výsledku v původním jazyce

Using dynamic, mass budget, and empirical models, we quantified sulphate-sulphur (S) leaching from soils in a large central European catchment (upper Vltava River, Czech Republic) over a 110-year period (1900?2010). S inputs to soils with synthetic fertilizers and atmospheric deposition increased in the 1950s?1980s, then rapidly decreased (80%), and remained low since the middle 1990s. The proportion of drained agricultural land rapidly increased from 4?43% between the 1950s and 1990s; then the drainingability of the system slowly decreased due to its aging. Sulphate concentrations in the Vltava exhibited similar trends as the external S inputs, suggesting that they could be explained by changes in atmospheric and fertiliser S inputs. The available data and modelling, however, showed that (i) internal S sources (mineralization of soil organic S in the drained agricultural land), (ii) a hysteresis in S leaching from forest soils (a net S retention at the high S inputs and then a net re
