Further phosphorus increases of more than 0.06 up to 0.12 ppm in the medium had no impact on the growth of Azolla. Eleven Azolla strains, including A. pinnata, A. mexicana, A. caroliniana, and A. filiculoides, were compared at the limiting concentration of phosphorus (0.03 ppm) in continuous-flow culture. Substantial differences among the species and strains were noted. For healthy growth, different species required widely differing phosphorus concentrations in the water medium. A. pinnata from Bangkok produced maximum yield and maximum frond area, and exhibited the better nitrogen-fixing capacity in the phosphorus limiting condition than limited condition than the New World Azolla species.
