Subproject 7

Nutrient Fluxes

To what extent do nutrients that are not removed with harvest products circulate through the interconnected production units for plants, insects and fishes?
Which measures can be used to increase the nutrient flow (cycle closure), and thus the nutrient use efficiency?
Is it possible to control the circulation of the nutrients by regulating controllable production factors, such as temperature or light, in order to positively influence the yield and quality of the food?

The scientists from subproject 7 ― which is truly interdisciplinary comprising work with fish, insects and plants including their growth media ― aim to shine a light into these questions. In order to trace the nutrients labeled stable isotopes are used.

Geilfuss, Christoph-Martin.jpg

Prof. Dr. Christoph-Martin Geilfus has a focus on plant nutrition of agricultural and horticultural crops. Besides, he studies apoplastic stress signalling in the context of guard cell regulation. For this, he uses methods ranging from live cell imaging over proteomics/ionomics to GWAS.
As member of the CUBES project, Mr. Geilfus aims to study nutrient fluxes and nutrient use efficiencies in the combined productions units for fish, plants and insects.
