Metabolic Adaptation, a Specialized Leaf Organ Structure and Vascular Responses to Diurnal N₂ Fixation by Nostoc azollae Sustain the Astonishing Productivity of Azolla Ferns without Nitrogen Fertilizer.

ABSTRACT: Sustainable agriculture demands reduced input of man-made nitrogen (N) fertilizer, yet N₂ fixation limits the productivity of crops with heterotrophic diazotrophic bacterial symbionts. We investigated floating ferns from the genus Azolla that host phototrophic diazotrophic Nostoc azollae in leaf pockets and belong to the fastest growing plants. Experimental production reported here demonstrated N-fertilizer independent production of nitrogen-rich biomass with an annual yield potential per ha of 1200 kg^-1 N fixed and 35 t dry biomass. ¹⁵N₂ fixation peaked at noon, reaching 0.4 mg N g^-1 dry weight h^-1. Azolla ferns therefore merit consideration as protein crops in spite of the fact that little is known abo
