Abstract in another language
Growing roots, soil structure and soil horizons may induce microscale heterogeneities of soilsolution chemistry and soil water content. To investigate heterogeneities on the centimeter scale,micro ceramic cells suitable for high resolution tensiometry and lysimetry have been developed, theconstruction of which is described in detail.The cells consist of a ceramic capillary with 1 mm diameter, connected to 1 / 16" ( 1.59 mm) PEEKtubing. When combined with a pressure transducer the micro ceramic cells act as tensiometer, whencoupled to a vacuum collecting device they can be used as micro suction cups. Also a combinedtensio-lysimeter was constructed, but this application is limited to lower soil matrix potentials.The micro suction cups showed a quick response to changes in the outer solution (breakthroughvolume < 80 izl). In initial field studies, the pH of the soil solution of an acid forest soil was measuredin high spatial resolution using a matrix of micro-lysimeters.
