Project background ## The position is embedded in «*PhenoMix*: Multidimensional field phenotyping of crop mixtures», a project of the ETH Zürich, the Swiss Data Science Centers and Agroscope. As part of *PhenoMix*, we are investigating mixtures of different pea and lentil varieties with wheat, oats and barley, which are grown on an experimental phenotyping platform and a neighboring field. In our work package, we collect the microclimate of the stand, plant characteristics and ecosystem services of pure cultures and mixtures. We use stable isotopes of carbon, nitrogen and water to capture light, nitrogen and water use and determine the complementarity of mixtures during three vegetation periods. Job description ## • You support the project team, in particular the two doctoral students in our group, in setting up, maintaining and caring for the field experiments. • You help with sampling in the field (plant and soil samples), with the investigation of nitrogen leaching and litter decomposition, as well as with microclimatic and ecophysiological measurements. • In addition to working in the field, you are responsible for preparing the samples in the laboratory, in particular for mass spectrometric analysis. • You also help the two doctoral students with data collection, quality control and evaluation of the collected data. • The position is limited to 3 years and will be filled as soon as possible from December 2026 as a full-time or part-time position (at least 60%).
