This study examined the effects of various levels of acidity, nitrogen, and phosphorus on the survival and growth of Paulownia tomentosa seedlings. The seedlings grew within a pH range of 7.0 to 4.0, but little or no growth occurred at pH 3.0. The seedlings grew well with nitrogen at 50 to 200 ppm and phosphorus at 5 ppm, but growth was greatly reduced below 10 ppm nitrogen. Higher levels of phosphorus need to be investigated.Abstract
