Abstract: The purpose of this study was to confirm a hypothesis that the cause of dying of pine trees in Shikishima-park at Maebashi-city was due to acidity of the soul.The pH level was lower at the area of pine tree dying than that of good grow.There was no marked decrease in the pH level at the points of stump where the saw chips were sprinkled.The changes in conditions of pine tress at 1997 and 2014 were also related to the changes in the pH levels of soil.The acidity rain and basement water were considered to be main causes of the fall and the recovery of pH, respectively, of the soil.The present results suggest that, because of the effects on environment, the recovery of pH level of soil may be much more important than the chemical treatment for Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle (MATSUNOZAI-SENTYU) and Monochamus alternatus Hope (MATSUNOMADARA-KAMIKIRI) to protect the dying of pine trees.
