Cover Story: Phragmites australis, Typha latifolia, T. angustifolia and Arundo donax are tall wetland plants that can replace fossil fuels under sustainable cultivation conditions. We investigated the biomethane production of these four species, including four different genotypes of P. australis, representing the species’ high intraspecific diversity. All plants were grown under three different nutrient supplies (no nutrients, equivalent of 75 kg N ha−1 year−1, equivalent of 500 kg N ha−1 year−1) in the white tanks seen in the photograph. Across all experiments, fertilization had little effect on biomethane yield (on average 222 ± 31 L kg−1 volatile solids (VS)). The genotypes of P. australis had similar biomethane production (226 ± 19 L kgVS−1). View this paper.
