Seven plantation-grown bottomland hardwoods, sweetgum (Liquidambar stryaciflua L.), green ash (Fraxinus pennsylvanica Marsh.), American sycamore (Platanus occidentalis L.), water oak (Quercus nigra L.), Nuttall oak (Q. nuttallii Palmer), cherrybark oak (Q. falcata var. pagodifolia Ell.), and swamp chestnut oak (Q. michauxii Nutt.), were sampled after the seventh growing season to determine foliar nutrient concentrations. Foliage samples were collected from the upper, middle, and lower crown positions and from the entire crown. Determinations were made for levels of nitrogen, phosphorus, potassium, calcium, and magnesium. Spacing had no effect on nutrient concentrations. Nutrient levels differed by crown position for some nutrients in most species. Most of the differences were in the nitrogen, calcium, and magnesium levels.
