Abstract
Aim of the study was to prove the evidence of a direct influence of solute input pattern (induced by canopy throughfall) on the pattern of groundwater solute concentration at the water table even at sites with groundwater table of 4-5 m below surface. The test site was a weakly buffered sandy soil with groundwater table ca. 4.3 m below surface (Podzol soil with some features of former gley process) under a cultivated pine stand (age ca. 60 years). Groundwater at the water table was sampled in between two rows of trees along a 30 m transect at 0.5 m intervals. As example, the results for sulfate concentration (the key solute of soil and groundwater acidification) show rather high variation along the transect. But a thorough stochastic analysis of empirical data sets reveals cyclic oszillations occurring synchronous and with same period length for sulfate concentration at the water table and for canopy coverage of the ground (and therefore for solute input). An additional long-periodic oscillation is strongly superimposing in the case of sulfate concentration. Thus the results indicate a direct influence of the pattern of canopy throughfall on the pattern of sulfate concentration at the water table. However, this influence is rather weakly pronounced at this deep groundwater site compared to corresponding shallow groundwater sites.
