| 751-5101-00L | Biogeochemistry and Sustainable Management | W+ | 3 credits | 2G | I. Feigenwinter, N. Buchmann, K.‑M. Kohonen | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | This course focuses on the interactions between ecology, biogeochemistry and management of agro- and forest ecosystems, thus, coupled human-environmental systems. Students learn how human impacts on ecosystems via management or global change are mainly driven by effects on biogeochemical cycles and thus ecosystem functioning, but also about feedback mechanisms of terrestrial ecosystems. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | Students will analyse and understand the complex and interacting processes of ecology, biogeochemistry and management of agroecosystems. They will use their theoretical knowledge in two flipped classroom exercises, but also set up a small weather station and program a data logger to collect meteorological variables, analyze large meteorological and flux data sets, and evaluate the impacts of weather events and management practices on the ecosystem greenhouse gas exchange. Thus, students will expand their computational competences. Moreover, students will be able to coordinate and work successfully in small (interdisciplinary) teams. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | Agroecosystems play a major role in all landscapes, either for production purposes, ecological areas or for recreation. The human impact of any management on the environment is mainly driven by effects on biogeochemical cycles. Effects of global change impacts will also act via biogeochemistry at the soil-biosphere-atmosphere-interface. Thus, ecosystem functioning, i.e., the interactions between ecology, biogeochemistry and management of terrestrial systems, is the science topic for this course. Students will gain profound knowledge about biogeochemical cycles and greenhouse gas fluxes in managed grassland and/or cropland ecosystems as well as expand their computational competences. Responses of agroecosystems to the environment, i.e., to climate and weather events, but also to management will be studied. Two flipped class-room exercises include the assessment of an ecosystem disturbance and the experimental design of an own study. Dataloggers will be programmed, and a small weather station will be set up. Different meteorological and greenhouse gas flux data will be analysed (using R) and assessed in terms of production, greenhouse gas budgets, and carbon sequestration. Thus, students will learn how to collect, analyse and interpret data about the complex interactions of a coupled human-environmental system. Students will work in groups (3-4 persons per group) with data from a small weather station (dedicated to the course), as well as data from the long-term measurement network Swiss FluxNet and from global databases. Data from the intensively managed grassland site Chamau will be used to investigate the biosphere-atmosphere exchange of CO2, H2O, N2O and CH4. Functional relationships will be identified, greenhouse gas budgets will be calculated for different time periods and in relation to management over the course of a year. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 751-3405-00L | Chemical Nature of Nutrients and their Availability to Plants: The Case of Phosphorus | W+ | 4 credits | 4G | E. Frossard | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | The CNNAP course discusses the mechanistic relationships between nutrient speciation in fertilizer and nutrient uptake by plants using phosphorus as an example. The course involves theoretical aspects of nutrient cycling, laboratory work, data analysis and presentation, and the use of advanced methods in plant nutrition studies. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | At the end of the CNNAP course, participants will obtain a mechanistic understanding of why and how the speciation of phosphorus in fertilizer can affect its release to the soil solution and subsequent uptake by plants. Students will be able to use this information for the development of fertilization schemes that maximize the nutrient uptake and fertilizer efficiency of crops or pastures. During the course, participants will become familiar with the use of radioisotopes and nuclear magnetic resonance as approaches to measure nutrient availability and forms, respectively and they will know the limits of these techniques. Students will also have the opportunity to improve their laboratory, presentation, discussion and writing skills. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Prerequisites / Notice | The CNNAP lecture will take place at the ETH experimental station in Eschikon Lindau every second year. The next course will be organized in autumn 2024. The CNNAP course will take place if and only if 8 or more students are registered one week before the start. See the location of the station at: http://www.plantnutrition.ethz.ch/the-group/how-to-find-us.html We strongly advise students who are planning to be absent for more than one week during the semester NOT to visit this course. Students should have visited the plant nutrition lectures in the 3rd and 6th semesters and the lecture pedosphere in the 3rd semester of the agricultural study program of the ETH. If students do not have visited these courses they will have to acquire the necessary information by themselves as this knowledge is indispensable for the CNNAP course. As the CNNAP course does not take place in autumn 2023, we recommend students interested in integrated assessment of nutrient cycling in soil plant systems to visit the 8th semester lecture 751-3404-00L (Nutrient Fluxes in Soil-Plant Systems: The Case of Nitrogen) organized in spring 2024 by Oberson et al. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
