Abstract

Abstract

Fertilization tests with small sawlog-size yellow-poplar (Liriodendron tulipifera L.) and red oak (Quercus rubra L.) were begun in the northern mountain section of West Virginia in the spring of 1970. Treatments were made with N, P, N-P, and N-P-K. During the first year, N was broadcast at 336 kg/ha, P at 97 kg/ha, and K at 93 kg/ha. Second season application included 112 kg/ha of N and 97 kg/ha of P. Basal-area response to N over a 3-year period amounted to a 47% increase for yellow-poplar and a 29% increase for red oak. There was no response to P, either alone or in combination with N. Negative effects on basal-area growth were observed where KCl was applied. Foliar response in leaf weight and color was attributed mostly to N, although P in combination with N produced slightly heavier and darker green leaves than N only. Foliar N in yellow-poplar corresponding to the best basal-area growth was about 3.0% N.
