dcterms:description

In the 2000 hydrological year, the watershed of Plešné Lake was a net source of acidity (H⁺ production of 29 meq m^-2 yr^-1), dominated by SO₄^2- release from soils (85 meq m^-2 yr^-1), NH₄⁺ retention in soils (40 meq m^-2 yr^-1), and NO₃^- release from soils N (22 meq m^-2 yr^-1). The release of Ca²⁺, Mg²⁺, and Na⁺ (85 meq m^-2 yr^-1) and ionic Al forms (56 meq m^-2 yr^-1) were major terrestrial H⁺ sinks. Ionic composition of tributaries showed seasonal variations mainly in NO₃^-, base cations, and Al concentrations. In-lake alkalinity generation (assimilation and denitrification of NO₃^-, SO₄^2- reduction, and photochemical/microbial decomposition of allochthonous organic matter) neutralized 58% of the In the 2000 hydrological year, the watershed of Plešné Lake was a net source of acidity (H⁺ production of 29 meq m^-2 yr^-1), dominated by SO₄^2- release from soils (85 meq m^-2 yr^-1), NH₄⁺ retention in soils (40 meq m^-2 yr^-1), and NO₃^- release from soils N (22 meq m^-2 yr^-1).
