Název v původním jazyce

A mass-balance study on chloride fluxes in a large central European catchment during 1900?2010

Popis výsledku v původním jazyce

Using data on long-term monitoring of water quality, mass budgets, and empirical models, we quantified chloride (Cl) leaching from diffuse and point sources in upper Vltava river (Czech Republic) during 1900?2010, with the major aim to evaluate the influence of historical changes in land use and management practices on Cl leaching from agricultural land. The Cl input to farmland in synthetic fertilizers, livestock feed, and atmospheric deposition tripled in the 1950s?1980s (from 23 to 64 kg/ha/yr on average), and then abruptly decreased to 14 kg/ha/yr during 1990?2010. The proportion of drained agricultural land rapidly increased from 4% in the 1950s to its maximum of 43% in the 1990s. Until the 1950s, the Cl leaching from agricultural land followed asimple dose-response function. Then, agricultural soils retained on average 16 kg/ha/yr of Cl during 1959?1985, when the most important changes in land use and management practices occurred, and subsequently became a net Cl source of 11 k
