|701-1695-00L||Soil Science Seminar||0 credits||1S||R. Kretzschmar, E. Frossard, D. Or, J. Six|
|Abstract||Invited external speakers present their research on current issues in the field of soil science and discuss their results with the participants.|
|Objective||Master and PhD students are introduced to current areas of research in soil sciences and get first-hand experience in scientific discussion.|
|751-3401-00L||Plant Nutrition I||2 credits||2V||E. Frossard|
|Abstract||The aim of these lecture is to present the processes controlling the uptake and transport of nutrients and water by the plant, the assimilation of nutrients in the plant, the effect of nutrients on crop yield and quality, the role of the soil as a source of nutrients for crops, and the basic principles of fertilization of different crop types using mineral and organic fertilizers.|
|Objective||At the end of the lecture, students know how mineral nutrients and water are taken up through roots and circulate in the plants and what their roles in plants are. They understand the importance of nutrients for yield formation and for crop product quality. They are able to propose fertilization plans adapted for field crops growing under Swiss conditions.|
|Content||A general introduction explains the needs of appropriately managing nutrients in plant production. Afterwards, we will study the physiology of plant nutrition (nutrient uptake by roots; water and nutrient transports in the plant; physiological roles of nutrients in the plant). Then the role of nutrients for yield formation and their effects on crop quality is dealt with. Finally, the bases of crop fertilization are taught (availability of nutrient in soil; N, P and K fertilization; different types of fertilizers).|
|Lecture notes||We will distribute a script for the part dealing with the physiology of plant nutrition. For the part on fertilization we will use the booklet of ACW and ART presenting the recommendations for the fertilization of crops and grassland in Switzerland (GRUDAF/DBF).|

|751-3405-00L||Chemical Nature of Nutrients and their Availability to Plants: The Case of Phosphorus |
Number of participants limited to 18.
|4 credits||4G||E. Frossard, T. I. McLaren, L. P. Schönholzer|
|Abstract||The course will present the principles underlying the use of radioisotopes in soil/plant systems. It will present how the introduction of an isotope into a system can be done to get some information on the structure of the system. Case studies will be presented to determine element availability. Finally, published studies from other groups will be analyzed and presented by the students.|
|Objective||At the end of this course the students are familiar with the principles on which radioisotope works are based and they have learned from case studies how radioisotopes can be used to obtain meaningful data. They are aware of the advantages of using radioisotopes in element cycling studies, but also of the risks and open questions related to isotope work.|
|Content||Radio-isotopes are extensively used at the soil/plant or ecosystem level to quantify the fluxes of elements (phosphorus (P), heavy metals, radionuclides) within a given system and to assess the importance of processes controlling these fluxes (e.g. exchange reactions between the soil solution and the soil solid phase, element turnover through the microbial biomass, organic matter mineralization etc.).|
The course will first present the principles, the basic assumptions and the theoretical framework that underlay the work with radioisotopes. It will present how the introduction of an isotope into a system can be done so as to get information on the structure of the system (e.g. number and size of compartments). Secondly, case studies on isotopic dilution and tracer work will be presented for instance on the isotopic exchange kinetics method to determine nutrients or pollutants availability. The case studies will be adapted to the ongoing research of the group of plant nutrition and will thus give an insight into our current research. In addition, published studies will be analyzed and presented by the students. Finally, the advantages and disadvantages of work with radioisotopes will be analyzed and discussed critically.
|Lecture notes||Documents will be distributed during the lecture|

|751-5115-00L||Current Aspects of Nutrient Cycle in Agro-Ecosystems|
Does not take place this semester.
This lecture will take place next year in autumn 2018.
|2 credits||1S||E. Frossard|
|Abstract||The seminar concerns current aspects and research related to nutrient cycles in agro-ecosystems. It offers to deepen the knowledge on a specific theme related to nutrients. It is composed by presentations of national and international speakers and by an excursion. The students write a report where they compile the obtained information, relate it to their own knowledge and include literature.|
|Objective||Listen and understand expert's presentations. Ask questions and contribute to the discussion during the talk sessions and the excursion. Link the information obtained during the seminar with knowledge from previous lessons and with literature searched to complement the matter. Expand the knowledge on nutrient cycles and nutrient management in the agro-ecosystem.|
