E. Matzner et Kj. Meiwes, LONG-TERM DEVELOPMENT OF ELEMENT FLUXES WITH BULK PRECIPITATION AND THROUGHFALL IN 2 GERMAN FORESTS, Journal of environmental quality, 23(1), 1994, pp. 162-166
Long-term monitoring of element fluxes with bulk precipitation and thr
oughfall in two forest ecosystems of the German Solling area revealed
substantial changes in the chemical climate of these ecosystems. From
1969 to 1990, fluxes of NO3 and NH3 in throughfall increased by 40 to
60%. In contrast, SO4, H+, and Ca fluxes decreased by 30 to 60%. The c
hanges of the element fluxes correspond to the development of emission
rates in Germany for dust, SO2, and NOx.
