Five rates of nitrogen,phosphorus and potassium fertilizers and agricultural limestone were applied to single tree plots of tuliptree Liriodendron tulipifera L., using a central, composite, rotatable design with 3 replications. Trees were old-field plantings of tuliptree and white pine Pinus strobus L. growing on Loudonville silt loam, a fine-loamy, mixed mesic Ultic Hapludalf that developed in Ohio in a thin layer of Wisconsin glacial till and locally disturbed sandstone and siltstone. Liming increased pH of the A horizon from 4.5 with no lime to 6 at the highest rate. The increase in soil pH was gradual and persisited for 33 years. After 33 years, sampling of lower soil horizons showed that the increase in pH extended into the B horizon. Liming also decreased the amount of extractable Fe, Mn, and Al. Sampling after 33 years showed that these decreases also extended into the B horizon. Liming increased calcium concentration and content in leaves, but had no effect on content or concentration of Fe or Mn. Foliage samples taken 17 and 31 years after liming had increased Ca/Al ratios with increasing rates of lime. We measured tree diameters and heights from permanent stations, using a Barr and Stroud dendrometer. Nitrogen was the only fertilizer that resulted in an increase in volume growth. Liming was without effect on tree volume increment or height growth so we conclude that pre-fertilization calcium supply in the soil was adequate for tuliptree.
