V obdobi vysokeho poklesu kysele depozice se depozice Mn prilis nezmenila z cehoz vyplyva ze zdrojem atmosfericke depozice Mn nebyly emise ze spalovani fosilnich paliv. Dalsim vstupem do lesniho ekosystemu bylo zvetravani, ktere podobne jako depozice dosahovalo 13 mg.m-2.rok-1 (celkem tedy vstupy byly 26 mg.m-2.yr-1), export Mn z povodi prostrednictvim povrchove a podzemni vody vsak cinil 43 mg.m-2.rok-1. Vnitrni latkove toky v ekosystemu dosahovaly vyznamne vyssich hodnot nez vstupy a vystupy. Latkovy tok v podkorunovych srazkach dosahoval 70 mg.m-2.rok-1, latkovy tok opadem 103 mg.m-2.rok-1 a rocni propad Mn prostrednictvim vegetace cinil 62 mg.m-2.rok-1. Vysoke obsahy a zasoby Mn byly nalezeny jak v biomase tak v pudnim pokryvu. Disproporce mezi vstupy a vystupy tedy muze znamenat ubytek Mn z techto zasob."@cs . .

"Manganese Biogeochemistry in a Central Czech Republic Catchment" . "Mn biogeochemistry was studied from 1994 to 2003 in a small forested catchment in the central Czech Republic using the watershed mass balance approach together with measurements of internal stores and fluxes. Mn inputs in bulk deposition were relatively constant during a period of sharply decreasing acidic deposition, suggesting that the Mn source was terrestrial, and not from fossil fuel combustion. Mn inputs in bulk deposition and Mn supplied by weathering each averaged 13 mg.m-2.yr-1 (26 mg.m-2.yr-1 total input), whereas Mn export in streamwater and groundwater averaged 43 mg.m-2.yr-1. Internal fluxes and pools of Mn were significantly greater than annual inputs and outputs. Throughfall Mn flux was 70 mg.m-2.yr-1, litterfall Mn flux was 103 mg.m-2.yr-1, and Mn net uptake by vegetation was 62 mg.m-2.yr-1. Large pools of labile or potentially labile Mn were present in biomass and surficial soil horizons."@en . . . . . "Navr\u00E1til, Tom\u00E1\u0161" .
