The influence of cutting cycle and plant spacing on carbon accumulation in willow aboveground biomass and soil were studied at Tully, New York. Willow clone SV1 was planted in 6.0 X 6.0 m plots at three spacing, 0.3 X 0.3, 0.3 X 0.9 and 0.6 X 1.1 m and harvested annually, biennially and triennialy. All plots were fertilized and irrigated. Among all treatment combinations, the greatest average annual aboveground carbon accumulation (13.6t ha-1 yr -1) occured in plants harvested triennially grown at 0.3 X 0.9 m spacing. Aboveground C content in plots harvested triennially was significantly greater than in annually harvested plots (but there was no significant difference between annually and biennially harvested plots). Aboveground C accumulation was not effected by plant spacing probably caused by competition among the plants at these dense spacings. Soil C content was not effected by harvest cycle or plant spacing.
