Abstract

A sweetgum plantation was established in 1975 to evaluate the effects of N, P fertilizers on growth and biomass accumulation. Positive response to the N and, to a lesser degree, the N + P treatment were noted the first year after fertilization. At age 5, total biomass averaged 2.5 T/ha: 25% leaves, 25% branches and 49% stems. Biomass accumulation was 50% greater on N treated plots than control.
