CUBES Circle (SP 07)

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 07 ― 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 labelled stable isotopes are used.
