Corner of Zezschwitz

Corner of Zezschwitz (born April 23, 1922 in Wünschendorf ; † March 1, 2003 in Coburg ) was a German soil scientist , agricultural chemist and geologist .

Life

Corner of Zezschwitz comes from the Meissnian nobility family Zezschwitz . Born in Wünschendorf in the Ore Mountains, he grew up on the family manor Deutschbaselitz near Kamenz in Saxony . After the end of World War II and the expropriation of his family in 1945 as part of the land reform , he stayed in West Germany .

After studying and doing his doctorate at the Hohenheim Agricultural University with a dissertation on the question of the evaluation of soil tests taking into account the conditions in Württemberg (1950/51), von Zezschwitz initially worked as an agricultural chemist at various research institutes and institutes. He worked at the agricultural research institute of Thomas phosphate producers in Essen-Bredeney , which was headed by Siegfried Gericke . There he mainly dealt with the behavior of phosphoric acid in the soil and the possibilities of phosphoric acid fertilization .

In 1958, Ecke von Zezschwitz moved to the Geological State Office in Krefeld , where he headed the “Special Mapping for Forestry ” department from 1959, first as a scientific employee and then from 1964 as a regional geologist until he retired in 1981. During this time, almost all of the state forests in North Rhine-Westphalia were mapped on a scale of 1: 10,000 . This large-scale forest soil mapping was one of his most important achievements.

His soil science work also influenced the practice of the entire Federal Republic in this area. Von Zezschwitz played a key role in both the first two editions of the Soil Science Mapping Guide and the third and fourth editions of the forest site survey. He also played a key role in developing the so-called “ grain size triangle”, which is part of the tool of the trade in soil science , a diagram with which the respective soil type can be determined very easily .

Von Zezschwitz has also shaped the humus forms of the forest and their determination. A series of his work on humus morphology between 1965 and 1968 led to the classification of typical forest humus forms in the north-west German low mountain range . He systematically worked out the criteria for addressing this. They were then included in the pedological mapping instructions as identification keys . Since then, they have been the basis for addressing humus forms in Germany and are taught at universities. From 1976 to 1994, Dr. Corner of Zezschwitz the working group forest humus forms of the German Soil Science Society , of which he was a member.

His findings were reflected in 85 scientific publications, mainly in the Geological Yearbook , but also in forest-related organs. At an early age, Ecke von Zezschwitz also took on teaching assignments and internships, including at the Forestry Faculty of the Georg-August University in Göttingen in Hann. Münden and later Göttingen . During excursions and in colloquia , he familiarized students and up-and-coming soil scientists with the determination of humus forms and their mapping.

Even in retirement, von Zezschwitz remained very active and published another 22 works, including the extensive presentation The soils of the Hardehausener Forest (forest district Neuenheerse ) (1988). In the course of the debate about the so-called " forest dieback " in the 1980s and 1990s, however, his focus of interest lay on the investigation of soil changes caused by the effects of immission .

The regional geologist Dr. Corner of Zezschwitz died on March 1, 2003 in Coburg, Upper Franconia.
