Dieffenbach, A; Matzner, E: Spatial heterogeneity of soil solution chemistry in the rhizosphere of a mature Norway spruce stand, Mitteilungen der Deutschen Bodenkundlichen Gesellschaft, 85, 225-228 (1997)
Abstract:
A new approach for non-destructive monitoring of soil solution chemistry in high spatial and temporal resolution for rhizosphere studies is presented. In a 510mmgrid, 30micro suction cups (;1mm) were installed in a rhizotron with Norway spruce (Picea abies [L.] Karst.) growing in low pH B-horizon soil. Roots grew through the grid, closely passing the suction cups. Soil solution composition before, during and after root passage was determined. For K+ and Mg2+ a significant decrease of soil solution concentration near root tips and elongation zones was observed, indicating a marked uptake of these elements. Mg2+ concentration was also significantly lowered when the root system aged, suggesting that this ion might also be taken up in older parts of the root system. No influence of growing roots was found on Na+-concentrations.
