ResumoA C T Fluxes of CO 2 were measured in a 75-ha short-rotation willow plantation at Enköping, central Sweden.The plantation was irrigated with wastewater for fertilization and water-filtering purposes.The harvested biomass was used locally for combined heat and power production.The plantation was a sink of ca. 8 tonnes C ha -1 during 2003, of which ca. 50% was estimated to be attributed to fertilization.Biomass increment by shoot growth was 5 tonnes C ha -1 during the same year.Belowground carbon allocation was estimated to 3 tonnes C ha -1 yr -1 by a model that relates carbon allocation to shoot growth.Thus, the ecosystem carbon balance was closed by these estimations.The carbon uptake by the willow plantation was 5.5 times as high compared to a normally managed spruce forest, but only half as high as from an experimental, well-managed willow plantation in the same region.This illustrates the vast potential of short-rotation willow plantations for CO 2 uptake from the atmosphere.
