Hans-Werner Olfs

Prof. Dr. Hans-Werner Olfs is a Professor of Plant Nutrition at the University of Applied Sciences Osnabrück, affiliated with the Faculty of Agricultural Sciences and Landscape Architecture. He holds a PhD from the University of Bonn (1992) and has extensive experience in agricultural research, including roles at Yara International and the University of Bonn. His expertise spans sustainable agricultural systems, nutrient management, and precision agriculture. He currently serves as Studiendekan and leads research projects funded by DBU and BLE, focusing on nitrogen efficiency, manure management, and environmental impact reduction.

• Educations: PhD in Agricultural Sciences (Plant Production) from University of Bonn (1992), studies at Universität Bonn (1980–1986).

Research interests include optimizing nutrient use efficiency, environmental impacts of fertilization, and sustainable farming practices. He has authored/co-authored over 50 publications and reviews for journals like Journal of Plant Nutrition and Soil Science and Crop Science.

Recent articles highlight innovations in manure analysis using NIR spectroscopy, nitrogen inhibitor efficacy, and ammonia emission mitigation. His projects address practical challenges like nutrient recycling and precision agriculture.

• Grants: Projects include 'NitriKlim' (Klimaschutzmaßnahmen) and 'Gülle2Laub' (manure-leaf compost optimization), funded by DBU and BLE.

Labs: Involved in plant nutrition and field experiments at the University's facilities. Collaborates with industry partners like Yara and agricultural associations.
