Silvia Hildegard Haneklaus
Silvia Hildegard Haneklaus (* October 17, 1959 in Rheine, North Rhine-Westphalia) is a German agricultural scientist and researcher specialised in Plant nutrition and Soil science. Life and Education 
Haneklaus was born in Rheine, the third child of the engineer Karl Haneklaus and his wife Erna, née Geburzky and was baptised a Catholic. Haneklaus attended from 1966 the catholic primary school in Rheine-Eschendorf. and from 1970 on the Emsland-Gymnasium in Rheine. She studied agriculture with specialization in plant production nutrition  at Christian-Albrechts-Universität zu Kiel (CAU)  and received her diploma 1985 in the discipline plant nutrition with a thesis about the essentiality of chlorine for plant life. In 1989 she completed her doctorate and received the title  “Dr. sc. agr.” at the Faculty of Agriculture in Kiel with a thesis about fertilizer strategies to combat uptake of radionuclides  by food plants in the aftermath of the reactor disaster in Chernobyl. Scientific career 
From 1990 to 1991 Haneklaus was principal investigator of a technology-transfer project for Precision agriculture (PA) at the Institute of Plant Nutrition and Soil Science at CAU in Kiel. 1991-1992 she worked as freelancer in PA for the Danish Agricultural Advisory Service, and on Remote sensing at the ‘Institute for Agricultural And Agroecological Innovations and Technologies”  (ILLIT) Ltd. in Kiel. 1992 Haneklaus became a senior scientist at the Institute of Plant Nutrition and Soil Science Bundesforschungsanstalt für Landwirtschaft in Braunschweig (FAL) where she implemented with Ewald Schnug international recognized competence centres for research on sulphur nutrition of crop plants and Precision agriculture. Fom 1997-1998 she was member of a governmental working group drafting government regulations to prevent radiation exposition of the public after nuclear accidents. In 2002 Haneklaus was appointed Director & Professor at the Federal Agricultural Research Institute (FAL), since 2008 Julius Kühn-Institut (JKI) in Braunschweig. Since 2010 she is acting as Secretary General for the International Scientific Centre of Fertilizers (CIEC) in Shenyang, China which was founded in 1933 in Rome. End of October 2022 she retired regularly at JKI. Awards 
In 2008, Haneklaus, was awarded the Diploma of Excellency of the Romanian Academy of Agricultural and Forestry Sciences ‘Gheorghe Ionescu-Şişeşti’. Research highlights 
Haneklaus contributed essentially to the development of the X-ray fluorescence method for the determination of the Glucosinolate-(GSL) content of rapeseed, which was employed already in 1987 nationwide during the harvest period of oilseed rape in order to differentiate old (high glucosinolate containing) (0-oilseed rape) cultivars from new (low glucosinolate containing (00-oilseed rape) varieties. Issues of sulfur nutrition of crop plants, with focus on resistance to abiotic and biotic stress were later one of her main research subjects. In 2001 Haneklaus coined with Ewald Schnug the term ‘Sulphur-Induced Resistance’ (SIR) which will become a major focus in the research portfolio of FAL/JKI. Later in her career she dedicated her research nutrinional and medical issues of uranium in food and water
