As a member of the Helmholtz Association, Forschungszentrum Jülich makes an effective contribution to solving major challenges facing society in the fields of information, energy,bioeconomy. It focuses on varied tasks in the area of research managementutilizes large, often unique, scientific infrastructure. Comework with around 6,100 colleagues across a range of topicsdisciplines at one of Europe's largest research centres.
The Institute of Bio-Geosciences – Agrosphere (IBG-3) conducts research to improve our understanding of biogeochemicalhydrological processes in terrestrial systems. Specific studies focus on environmental controls on biogeochemical cycling of elements, the analysis of exchange processesnutrient dynamics in the soil-plant-atmosphere continuum. A combination of experiments, modellinginnovative observation technologies is used to bridge the gapmodel, processmanagement scale. Its research contributes to the sustainableresource-conserving use of soilswaterto the quantification of the effect of climateland use change on terrestrial ecosystems.
We are offering a
PhD position on microplastic effects in the rhizosphere of cropsThe work will be conducted in the project “µPlasticUnderstandingmitigating microplastic effects on rhizosphere processesinteractions in agricultural soils”, which is part of the program of the German Federal Ministry of EducationResearch (BMBF) “Plant rootssoil ecosystems: Importance of the rhizosphere for the bioeconomy” in the framework of the “National Research Strategy Bioeconomy 2030”. The µPlastic project aims at elucidatingquantifying key physical, microbiologicalbiogeochemical processes associated with microplastic pollution of the soiltheir effect on crop growth, water uptake as well as carbonnitrogen turnover in the rhizosphere. We will conduct a series of experiments in potsnewly developed rhizotron systems to study the effects of microplastic particles on root developmentperformance as well as on microbial abundanceactitivity. You will be responsible for conducting potrhizotron experiments using non-destructivedestructive techniques, such as microdialysis, magnetic resonance imaging,infrared laser absorption spectroscopy in combination with stable isotope labelling to quantify root waternutrient uptake, root exudationrhizosphere soil carbonnitrogen turnover as a function of microplastic materialload, crop speciesroot developmental stage. Furthermore, also the fate of the microplastic particles (degradation) will be followed with electron microscopyother techniques.
Your tasks in detail:
