BAM Fungus Cellar

 

Facility Information

Organization: Bundesanstalt für Materialforschung und -prüfung BAM
Contact person: Dr Ina Stepan / Christian Reger
Who uses it or can use it?: BAM scientists for research & testing
Is it a contract testing site? Yes
Location: Unter den Eichen 87, 12205 Berlin, Germany
Coordinates: 52.44293564994835, 13.28800496337979
Floor area approx. (m2): 230 m2 (Soil area 87 m2)
Moisture application: Waterdrops from above (“gentle rain”)
Moisture Control system: The moisture content of the soils is adjusted by an electronically controlled sprinkler installation to produce and maintain a moisture range in the stakes that promotes fungal attack of the wood.
Soil moisture measurement: Tensiometer for measuring the soil matric potential
