Inst. für Pflanzenwissenschaften, Gruppe Pflanzenernährung, ETH Zürich - The Group of Plant Nutrition is a multidisciplinary team consisting of soil scientists, agronomists, biologists and administrative / technical staff. - Our research and teaching focus on element cycling in agro-ecosystems; in research we place emphasis on the processes and mechanisms that control the transfer of elements from the soil to the roots. - Our aim is to propose concepts to ensure adequate mineral nutrient supply to crops while maintaining the natural resource base and minimizing negative impacts on the environment. - As a partner of several national and international institutes, we contribute to a general research effort aimed at improving agricultural systems towards sustainable production.
