Název v původním jazyce

Mass balance of nutrients and major solutes in the Plešné watershed-lake ecosystem in the 2001 hydrological year.

Popis výsledku v původním jazyce

Fluxes of major ions and nutrients were evaluated in Plešné Lake and its watershed in the 2001 hydrological year. The net terrestrial proton production (15 keq/yr) resulted predominantly from net sulfate and nitrate release from soils, and ammonia assimilation. The net in-lake proton consumption (22 keq/yr) resulted mostly from reduction in nitrate (55%), organic acid anions (24%), and sulfate (13%). The external inputs of total organic C, total N, total P, and dissolved Si were 6520, 908, 19.9, and 3158 kg/yr and their net in-lake removals were 10%, 24%, 54%, and 28%, respectively. Sedimentation fluxes of C, N, and P from the epilimnion were 1990, 211, and 8.9 kg/yr, and their average accumulations in the sediments were 1585, 151, and 13.4 kg/yr respectively. The absence of nitrification due to long-lasting water acidification led to a situation in which the lake became a net source of ammonium-N (78 kg/yr).
