Ein Verfahren zur Gewinnung der Gleichgewichts-Bodenporenlösung

A procedure for obtaining the equilibrium soil pore solution A percolation system for 100 cm³ soil cores is presented. Only filter materials with negligeable interferring properties are used, and during percolation an air filled porosity is maintained. Results from soil cores of a spruce site show, that conventional homogenization of soil samples may lead to a great loss of information about the variability of acidity parameters and to an underestimation of the real soil acidification in the rhizosphere.
