Abstract
Nutrient removal during stem harvest was evaluated in a one-year rotation willow bioenergy plantation. For the stem nutrient content, the stem biomass and stem nutrient concentration were collected in the winter of 1987-1993 from the established willow plantation at Tully, New York, U.S.A. in 1987. Five willow clones and one hybrid poplar clone were planted. Half of the plots were fertilized annually with
목재에너지 공급을 위해 1987년 미국 뉴욕주립대 연습림에 조성된 버드나무(Salix spp.) 조림지를 대상으로, 매년 벌채되는 지상부 biomass와 양분의 양을 측정하여 벌채에 의한 양분수탈을 평가하였다. 5개의 버드나무 clone과 1개의 잡종 포플러가 식재되었으며, 식재지의 시비구에 매년 N(
