Plots in seven eastern white pine sawlog stands were treated with nitrogen at rates of 0, 56, 112, and 224 kg/ha. After four years the largest increase in basal area growth, 0.31 dm2 /tree, and volume growth, 13.0 m3 /ha, occurred in plots that received 112 kg/ha. It appears that an application rate of 112 kg/ha may provide a real return of 15% or more in some stands.
