Micro lysimetry as a tool for studying soil solution chemistry in the vicinity of growing roots
BITÖK-N 8
From 01/1995 to 12/1997Principal Investigator: Egbert Matzner
Staff: Antje Dieffenbach, Axel Göttlein
Grant: 0339476 B Vorhersage und Erklärung des Verhaltens und der Belastbarkeit von Ökosystemen unter veränderten Umweltbedingungen
The aim of our project was to investigate microscale variabilities of soil solution chemistry which are caused by soil structure, soil horizons and the activity of growing roots. We used micro suction cups as sampling device and capillary electrophoresis for ion analysis.
Within a soil profile gradients of soil solution chemistry an of as soil solid phase characteristics could be observed on very short distances (<2 cm). Steep concentration gradients at visible soil horizon borders could not be observed. At this scale it was also not possible to identify regulation mechanisms between soil solid phase and soil solution chemistry. We observed distinct differences in solution concentrations of Al
Micro suction cups and capillary electrophoresis proved to be a powerful tool for investigating spatial and temporal variations of soil solution chemistry, with the essential advantage that Al
