Chapter 5. Changes in Concentrations of Dissolved Solids in Precipitation and Discharged Water from Drained Pasture, Natural Wetland and Spruce Forest During 1999-2006 in Šumava Mountains, Czech Republic
Original language description
Changes in the chemistry of bulk precipitation and stream water between 1999 and 2006 are described for small drained, wetland and forest catchments located within Šumava Mountains (Bohemian Forest) in south-west of the Czech Republic. In bulk precipitation, the annual mean pH increased from 4.8 to 5.4, concentrations of base cations were relatively low and constant over time, nitrate moderately increased, conductivity and alkalinity decreased, while sulphate decreased (from 16.8 mg l?1 to 7.2 mg l?1) during the 7 year monitoring period. Catchments with wetland and forest appear to be more resistant to recovery in terms of water conductivity, alkalinity and base cations in comparison with the relatively fast response from the drained pasture. High nitrate, bicarbonate and base cations concentrations in the stream water discharged from the pasture indicate continuous acidification of the catchment, and they result most probably from fast mineralisation (oxidation) of soil organic matter

Kapitola 5. Změny chemismu srážek a povrchových vod ve třech různých malých povodích na Šumavě
Czech description
Změny v chemismu srážek a povrchových vod byly sledovány v letech 1999 až 2006. Výsledky ukazují nárůst pH, stabilní koncentrace basických kationtů, mírný pokles vodivosti a alkality a významný pokles koncentrace síranů. Tyto změny byly výraznější na odvodněné pastvině, zatímco lesní povodí a mokřady vykazovaly stabilnější úroveň sledovaných parametrů. Zvýšené koncentrace dusičnanů a alkality v potoce, který odvodňuje pastvinu, mohou svědčit pro rychlejší mineralizaci organických látek v odvodněném půdním horizontu.
