Abstract in another language

To evaluate ecosystem response to changing atmospheric deposition, element budgetswere established over the period from 1973 to 1991 for a Norway Spruce (Picea abies (L.) Karst.)site. Budgets for Na +, CI-, Ca 2+, Mg 2+, N, S and H + were based on total deposition and seepagewater fluxes. The deposition of Ca 2+, Mg 2+, particularly, of S and H + decreased with time, whilecalculated N deposition remained constant at a high level. The decrease in Ca 2+ deposition led to2+ a reduction of Ca 2+ fluxes with seepage water. The decrease of Mg depos1't1' on did not have aneffect on the output fluxes of Mg 2+. The reversibility of soil and seepage water acidification byreduced S deposition was delayed by the release of previously accumulated soil SO]-. The highestNOr fluxes were observed during the period of 1986 to 1988; NO~- fluxes in general demonstrateda considerable annual and periodic variation. Total N accumulation in the ecosystem amounted tonearly 590 kg ha-1 yr- 1 during the observation period. The major sink of N in the spruce site is theaggrading humus layer. The results emphasize the need for measurements over several years to makeconclusions regarding the function of ecosystems in response to atmospheric deposition.
