Laboratory

The soil lab provides broad spectrum of analytical options for research and teaching. Soil and sediment analysis as well as environmental chemistry are in the focus.

Directions to "Standort West".

Equipment

Druckplatten-Extraktoren

AAS

Pressure plate extractors for the determination of correlations between moisture content and soil-moisture tension (pF value)
