Title: Wetland energy crops. [Marshes and swamps]

Conference ·
OSTI ID:5286962

The use of wetlands to produce biomass crops has been the focus of several research programs at the University of Minnesota. There are over 14 million acres of peatlands in the northern lakes states, Minnesota, Michigan, and Wisconsin. Currently only 2.7% of Minnesota peatlands are utilized for crop production. Typha spp. (cattails), Phragmites communis (reed grass), Carex spp. (sedges), Phalaris arundinacea (reed-canary grass), Alnus spp. (alder) and Salix spp. (willow) are some species being considered as possible wetland energy crops. Typha looks particularly promising; it grows naturally in monocultures, is easily propagated from seed or rhizomes, and is very productive. The total biomass of natural Typha stands often exceeds 40 dry tons/hectare; annual yields from stands established from rhizome pieces range from 25-30 tons/hectare while stands established with seed yield 8-12 t/ha the first season and 15-20 t/ha by the second season. Studies of harvesting methods, land use considerations, possible environmental constraints, and the overall economics of wetland energy crop production are currently under way.
