Postdoc in Characterization of P forms in soils and societal P resources (28 months)

Copenhagen University

Denmark

February 27, 2022

Description

Do you want to contribute to the development of solutions for recovery and recycling of phosphorus that are more sustainable?

We are looking for a dedicated, well-organized, communicative and highly qualified post doc, to carry out the project described below, in the Soil Fertility group at the Department of Plant and Environmental Sciences, University of Copenhagen.

The post doc project will unfold within the framework of PROCESSOR – Phosphorus recycling from complex scarcely soluble societal resources – letting the soil do the work

The project will be executed in collaboration with partners from ETH (Emmanuel Frossard and Astrid Oberson), University of Rostock (Peter Leinweber) and Department of Geosciences and Natural Resource Management, Copenhagen University (Carsten Müller).

Background:

Recycling of societal resources of phosphorus (P) defined as sewage sludge, meat and bone meal and their corresponding ashes is an essential step towards a circular green economy. We propose that the resources can be used ‘as they are' without further treatment, since potentially toxic element (PTE) content in sewage sludge (and its ashes) has decreased in many European countries, in some cases close to background levels, while other contaminants in sewage sludge are of low concern. Bonemeal has a very low content of PTE's.

However, the longer-term phosphorus fertilizer value of these resources and their intricate interactions with a suite of soil characteristics is very sparsely understood. In this project, we will for the first time address this issue across a range of agronomically important European soils, using relevant complex societal resources. By doing so, we will be able to formulate a strategy for efficient use of these resources in Europe to decrease the import of phosphate, which has been identified by the EU as non-substitutable and of high economic importance.

The work of the postdoc project will be mainly centered on characterization of soils and P-containing products with solid state methodologies, supplemented with analyses of P availability with isotope exchange kinetics or ion sink assays, and complemented by routine wet chemical methods. The work on P speciation in soils and societal P resources will be carried out in close collaboration with another post doc working on long-term phosphate dynamics in soil.

Further information on the Department is linked at https: // www. science.ku.dk/english/about-the-faculty/organisation/. Inquiries about the position can be made to Jakob Magid (jma@plen.ku.dk).

The position is open from 1 April 2022 or as soon as possible thereafter.

The University wishes our staff to reflect the diversity of society and thus welcomes applications from all qualified candidates regardless of personal background.

Qualifications

The candidate should possess the following qualifications

  • A Ph.D. and background as an environmental scientist or equivalent
  • Good understanding of Phosphorus geochemistry/biogeochemistry
  • Practical experience with solid state methodologies – e.g. XRD, XANES, SEM-EDX, 31P MAS SS NMR to characterize mineral P forms and e.g. 31P liquid state NMR to characterize organic P forms.
  • Practical experience with wet chemical analyses of phosphorus in soils and residues
  • Good interpersonal skills
  • Excellence in writing and speaking English
