Ewald Schnug, 2014

Ewald Schnug (born September 7, 1954 in Hachenburg , Westerwald ) is a German agricultural scientist, university professor and researcher specializing in plant nutrition and soil science .

Life

Schnug grew up as the first son of the gardener Ewald Schnug and his wife Marianne, née. Haas, on his parents' business in Altenkirchen in the Westerwald. He was married from 1975 to 2005 and has three grown daughters.

Education and academic background

Schnug first attended the Catholic elementary school in Altenkirchen and graduated from high school in 1974 in the natural science branch of the Westerwaldgymnasium in Altenkirchen. In 1978 he received his diploma in plant production from the Christian Albrechts University in Kiel . In 1982 he received his doctorate. sc. agr. at the agricultural faculty there, where he also completed his habilitation in 1989. In 1992 he received the title of Dr. rer. nat. habil. at the natural science faculty of the Technical University Carolo Wilhelmina in Braunschweig .

job

From 1979 to 1992 he worked at the Institute for Plant Nutrition and Soil Science at Christian Albrechts University in Kiel. First as a research assistant until 1983, then as a university assistant until 1989 and finally as a junior professor until 1992. Between 1982 and 1990 he also taught applied chemistry at the University of Applied Sciences for Agriculture in Rendsburg. In 1984 he founded the Institute for Agricultural and Rural Ecological Innovations and Technologies (ILLIT) GmbH in Kiel, which he headed until 1994 as partner and director R&D, CEO. As a scholarship holder of the Heisenberg Foundation, he completed teaching and research stays in Newcastle upon Tyne and Aberdeen between 1990 and 1992 . From 1992 he headed the Institute for Plant Nutrition and Soil Science of the Federal Research Center for Agriculture in Braunschweig (FAL) and since 2008 the Institute for Plant Production and Soil Science of the Federal Research Institute for Cultivated Plants, Julius Kühn Institute in Braunschweig / Quedlinburg. Since 1996 he has also worked for the International Scientific Center for Fertilizers and Fertilization (CIEC), founded in Rome in 1933. From June 1996 to September 2010 he was Vice President for Research and Strategic Planning, subsequently the first German President of the Society and since September 2019 its second Honorary President.
