Abstract

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.
