Innovation

Azoll lla, , a novel su

sustainable cr crop which can be grown in independent t of f Haber-Bosch fertil tilizer

PhD Thesis Paul Brouwer, 2017

Haber-Bosch Reaction

Erisman et al., 2018

Global Problems

• 80% of nitrogen in our body is Haber-Bosch nitrogen
• 2% of the world’s total energy production
• Environmental problems and threat to water life biodiversity

Dreschel, 2017

Bio-Utilization of Symbiont

Nostoc azolla llae fix fixes atm tmospheric nitr itrogen in into organic nitr itrogen Azolla pinnata 600 – 1000 kg nitrogen ha-1 y-1 Glycine max 60 – 200 kg nitrogen ha-1 y-1
