discussing grassland humusforms
In 1976 the working group was founded by the German Soil Science Society at the request of Prof. Dr. Mückenhausen. The working group was authorized to stratify the humusforms systematically und to train students and soil surveyors. The first chairman was Ecke von Zezschwitz. At present the group is leaded by Christine Wachendorf (University of Kassel).
