Abstract
The mean above-ground biomass of reed,Phragmites australis, in closed South Swedish stands was found to be 1 kg dry weight. m−2 in August. Leaves, which are shed in the autumn in contrast to culms that remain standing, represent 26% of the total shoot weight. Because part of the culm will be covered by water, ice and snow 0.5 kg dry weight. m−2 is available for winter harvest. Nutrient concentrations in shoots decrease throughout summer and winter. Although part of the maximal summer standing stock of N, P and K is lost in shed leaves, 55%, 75% and 80%, respectively, can potentially be recycled to rhizomes. Nitrogen fertilization and removal of standing litter in winter can increase above-ground biomass production in reed stands. Reed culms, cut in winter with agricultural machinery or amphibious harvesters, have been tested as a fuel for heating purposes in Sweden
