Effects of thinning and fertilization on growth and foliar nutrients were studied in pole-size sugar maple (Acersaccharum Marsh.). Thinning plus fertilization resulted in significantly lower concentrations of foliar N, P, K, Mg, Cu, Zn, B, and Al in the first growing season, and of Mg, Cu, Zn, and Al in the 2nd year. Foliar nutrients in released, but nonfertilized, trees exhibited similar trends. The decreased foliar nutrient concentrations are attributed to dilution effects as a result of increased growth.Fertilization with N, P, and K significantly increased foliar concentrations of those nutrients but did not stimulate radial growth. Thinning resulted in highly significant increase in diameter growth both years.
