Note(s): Freshwater weed crops are capable of simultaneously providing advanced treatment (nutrient removal) of wastewater passed through them and producing biomass that may be converted to fuel by anaerobic digestion. Performance of both functions depends upon the rate of primary organic production of the plant species in question. Annual yields of the floating species Lemna minor (duckweed) and Eichhornia crassipes (water hyacinth) and of the submerged species Hydrilla verticillata were determined in central Florida. Yields of duckweed and Hydrilla, 13.5 and 15.3 m tons/ha.year respectively, are comparable to many temperate terrestrial food and grass crops. The yield of water hyacinths, 88.3 m tons/ha.year, is among the highest documented for any plant species on earth.Florida Atlantic University.
